Fast, Simple Noise Triage That Saves Us Time **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Philanthropy | Mid-Market (51-1000 emp.) **Reviewed Date:** March 03, 2026 **What do you like best about GreyNoise?** What I love about GreyNoise is how quickly and easily the search tells us, that the traffic is just background internet noise or something we should forward to the team. That alone has saved us so many unnecessary tickets and saved us a lot of time. The interface is simple to use and lookups and the context area for each origin gives us exactly what we need to understand. **What do you dislike about GreyNoise?** GreyNoise is a great tool, no question about it but there has to a better onboarding and documentation. The first couple of weeks were a little overwhelming but apart from that it is a well built security platform. **What problems is GreyNoise solving and how is that benefiting you?** The biggest problem we had before GreyNoise was alerts. Before we started using GreyNoise, we didn’t realize how much time we were wasting on simple scanners. As a nonprofit even with few alerts the team is helping up. After GreyNoise, we are now able to filter out known safe hits and focus only on traffic that was actually suspicious. ### 12. The best available tool for IP scanning and strongest firewall tuning **Rating:** 5.0/5.0 stars **Reviewed by:** Gharib T. | Security Analyst II, Small-Business (50 or fewer emp.) **Reviewed Date:** December 05, 2025 **What do you like best about GreyNoise?** The tool gives me a clear analysis of malicious IPs scanning the internet and shows when the activity was first and last observed, what kinds of scanning behavior were detected, and points us toward the next steps on how to protect our devices that connect to the internet regularly and ensures our firewall is active. **What do you dislike about GreyNoise?** Providing more support documentation could be very helpful when we get an error and make it quicker to get to the correct answer. **What problems is GreyNoise solving and how is that benefiting you?** Makes it very easy and secure to check each IP reputation before connecting to the internet and it managed our firewall effectively. This gives us the ability to block compromised URLs and domains so that devices cannot connect to them. ### 13. GreyNoise Saves Me Hours Each Week by Filtering Out Junk Alerts. **Rating:** 4.0/5.0 stars **Reviewed by:** Ivan K. | CTO, Mid-Market (51-1000 emp.) **Reviewed Date:** September 23, 2025 **What do you like best about GreyNoise?** I use GreyNoise to prescreen alert noise to get to relevant content. On a typical day, I use it with my SIEM alerts to see if an IP that is incoming is a mass scanner and nothing more. It is very useful in reducing false positives and as a result I no longer spend hours chasing noise. The context that it provides almost immediately is swift enough to make a decision. I can decide whether to escalate or if I can simply walk away. **What do you dislike about GreyNoise?** I sometimes feel that there are unnecessary streamlining interfaces. I have to navigate more than I want to and spend more time than required. I do wish that temporal lookups were faster when I need to go more than two weeks deep in my logs and I also still have to spend time investigating myself. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise greatly diminishes the alert fatigue I experience by tagging noise that will not compromise my time and will rather protect my focus on the alerts which matter. It saves a lot of time every week and honestly, helps to lessen the stress on the time I spend on investigations. I no longer have to second guess every random IP that pops up. ### 14. Effortless Threat Detection and Valuable Context for Network Security **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer & Network Security | Mid-Market (51-1000 emp.) **Reviewed Date:** December 04, 2025 **What do you like best about GreyNoise?** It’s one of the easiest tools to check for opportunistic scanning activity for suspicious IP addresses observed in our network logs. **What do you dislike about GreyNoise?** It’s difficult to think of anything specific off the top of my head, but I think it may be useful for community users to be able to flag IP addresses that have yet to be observed by GreyNoise’s tooling as being potential scanners in some manner, in a similar manner to things like the community tab on VirusTotal. **What problems is GreyNoise solving and how is that benefiting you?** It helps to provide a lot of context for our monitoring and has helped us to identify assets that were unintentionally internet facing - in finding a suspicious IP address being already identified by their honeypot services as opportunistically scanning and the ports matching the connections we’ve seen, we have been able to pivot across to tools like Shodan and verify the exposure of the assets we have seen those IP addresses attempt to interact with. It’s enabling us to manage and monitor our estate more effectively. ### 15. GreyNoise Makes Unusual Traffic Easy to Understand and Act On **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Research | Mid-Market (51-1000 emp.) **Reviewed Date:** February 26, 2026 **What do you like best about GreyNoise?** Because we host open access scientific data, we naturally see a lot of unusual, automated traffic every day. It helps us very much in understanding what is safe traffic and what something we should look into. GreyNoise gives us very simple informing on what we should do and provides status when something looks suspicious. **What do you dislike about GreyNoise?** It’s a great tool for non profits who are in need of security tool about traffics but the interface could be made better. Some commonly used features require a few extra clicks for us to use and feels a bit full when we review IPs by file upload. **What problems is GreyNoise solving and how is that benefiting you?** Like many non-profits, we don’t have a full time security operations inside our team. GreyNoise solved that problem and help us avoid accidentally blocking normal visitors. It proves the scan data where anyone can understand and this allowed us to protect us better. ### 16. Excellent Tool With Advanced Threat Detection Capabilities. **Rating:** 4.5/5.0 stars **Reviewed by:** Nguto C. | Network Security Architect, Mid-Market (51-1000 emp.) **Reviewed Date:** February 02, 2026 **What do you like best about GreyNoise?** What I like most about GreyNoise is how it helps me understand the kind of activities happening against our systems. I love how it checks for network vulnerabilities and helps to track remediation more effectively and more clearly. GreyNoise is the market leader in cyber security management. **What do you dislike about GreyNoise?** I haven't yet found any limitations with GreyNoise as it meets our expectations. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise provides quick analysis for newly released CVEs which is very helpful for quickly taking action on zero day vulnerabilities. ### 17. The Most Efficient Way I Have Found to Determine If an Alert Is as Important as It Claims to Be. **Rating:** 5.0/5.0 stars **Reviewed by:** Nathan H. | President, Small-Business (50 or fewer emp.) **Reviewed Date:** September 10, 2025 **What do you like best about GreyNoise?** I utilize GreyNoise as an invaluable time saving tool and its very helpful in determining if an IP logging to my systems is worth my time or is just noise. Instead of spending time pursuing a false positive, I can initiate a cross-check of any suspicious activity, and in a moment, distinguish a mass of scanners that is visible to a few, and something that is unique to me. This helps me streamline my investigations and focus toward legitimate threats rather than sifting through a ton of irrelevant data. **What do you dislike about GreyNoise?** Once in a while, I wish that the information around specific IPs was a bit richer. I sometimes need more context around what specific steps the scanner was executing. I find the web tool somewhat of a pain, especially when I want to execute a number of queries in quick succession. I find myself having to rely on their API for bulk checks. It works well, although it takes more time to automate the surrounding steps. It’s not a dealbreaker, but it could be a bit more efficient. **What problems is GreyNoise solving and how is that benefiting you?** Because of GreyNoise, I no longer spend time pursuing activities that are irrelevant, which, in turn, helps me instantaneously focus on the legitimate threats. It allows me to streamline my work, and is of great help when I need to determine the focus of my attention in the work environment. ### 18. GreyNoise: Speeds Up Threat Detection While Cutting Down SOC Noise. **Rating:** 4.5/5.0 stars **Reviewed by:** Armaghan S. | Digital Marketing Executive, Small-Business (50 or fewer emp.) **Reviewed Date:** September 02, 2025 **What do you like best about GreyNoise?** I learn to love GreyNoise for the same reason I truly hate modal cybersecurity noises false positives namely that when an alert does sound it will actually get noticed. A clear and easily adaptable interface along with strong integration makes this an easy product to get started with for my team. Be it, automatic EDR SOAR or any of the existing tools rich in alerts gives a boast to an over 90% faster incident response workflow. **What do you dislike about GreyNoise?** Some of the UI seems a little outdated, and the ridiculously small characters can make for tiring eyeball sessions in the long run. Once in a while, it doesn’t automatically load the data from our EDR; I have to cross-verify it myself, which breaks the flow. Ones that immediately come to mind would be AI-driven to increase the speed of identifying newly emerged threats-something Recorded Future is already dipping its toes into. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise is like having the ability to very quickly filter out or distinguish between the background noise that is irrelevant or automated from the internet and what’s not, allowing the drowning free flow of useless alerts to be focused on real incidents. This has been a game-changer with large clients where daily event volumes used to overwhelm our SOC team. ### 19. Flexible internet firewall offering a solid protection layer against network attack **Rating:** 5.0/5.0 stars **Reviewed by:** Barosio R. | SOC Team Lead, Mid-Market (51-1000 emp.) **Reviewed Date:** December 03, 2025 **What do you like best about GreyNoise?** GreyNoise offers complete network protection especially for our company that requires strict data compliance. The real time scanning of the internet is very effective and its great at analyzing possible domain infection enabling us to stop access to such unwanted domains. The program is able to block IP address that indicate they are infected with malware. **What do you dislike about GreyNoise?** A con would be that the management console is not the quickest one I’ve seen. **What problems is GreyNoise solving and how is that benefiting you?** It provides multiple levels of security to our organization’s network providing the ability to do URL access exclusions and blocking IP addresses attempting to exploit NoSQL command injection in Cockpit CMS. ### 20. GreyNoise: Cutting Through Internet Clutter for Identifying Real Threats **Rating:** 4.0/5.0 stars **Reviewed by:** Praneeth V. | Senior Project Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** August 18, 2025 **What do you like best about GreyNoise?** I really like GreyNoise for the way it shields my vision of the internet; it sifts out all that background noise and lets me concentrate on actual threats instead of running around after benign scanners. The fact that it was easy to integrate was a huge advantage; I was able to incorporate it into my workflows without much trouble. Their dashboard is user-friendly and provides me instant information without making me read a heap of jargon. **What do you dislike about GreyNoise?** At times, the pricing tiers can be confusing, and I would like them to be clearer on usage limits. Much like Cloudflare, GreyNoise can at times be almost ‘too simple’ on first use, leaving some advanced features not quite so obvious to power users. I would love to see more options for filtering and alerting, though, so that it speaks more to techies that like fine-tuning. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise helps in avoiding too many alerts by drowning out background noise from broad scanners. I used to spend hours chasing down benign IPs before this. Now I can confidently filter them out. Compared to something like Shodan or ThreatMiner, GreyNoise feels built for the purpose: cutting noise and directly translates into saved time and peace of mind. ### 21. Great vulnerability detection power that leaves no escape to any threat **Rating:** 5.0/5.0 stars **Reviewed by:** Ruben S. | Threat Analyst, Mid-Market (51-1000 emp.) **Reviewed Date:** November 02, 2025 **What do you like best about GreyNoise?** It offers continuous monitoring of IPs and promptly blocks any suspected threats and alerts me especially when accessing dangerous files from untrusted websites. I can check the security status of a website very easily, detect TLS/SSL crawlers, and block IP addresses that have been observed attempting to negotiate an SSH session. **What do you dislike about GreyNoise?** It may slow down some computational processes, mainly the startup if you have to keep it always activated while the computer is on. **What problems is GreyNoise solving and how is that benefiting you?** Protects all our devices and servers from threats such as viruses, malware, and phishing. It’s real-time scanning of REST API authorization enables us to block installation of vulnerable versions of Wordpress plugins that have been closed. ### 22. Helps Me See What Really Matters in Our Alerts **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** October 27, 2025 **What do you like best about GreyNoise?** One thing I really do value about GreyNoise is how it helps me see patterns and when a new payload has begun spraying across the internet well before our other tools have even raised a flag or when two campaigns start adopting each other’s methods. It’s my fast reality check before I escalate and it has rescued me from chasing unnecessary stuff far too many times to count. **What do you dislike about GreyNoise?** I sometimes want to see enrichment data go deeper and perhaps by displaying some context around new actors or linking out to threat reports from right within the dashboard. I also find the historical view a bit shallow when I’m trying to track activity over many months. And even though the API is powerful, it tends to chug a bit when I have to download huge swaths of data for retroactive review. **What problems is GreyNoise solving and how is that benefiting you?** Our analysts were pissing hours clicking on shitty things before we took it and only to find mundain port scans and cimetary trash. But now we can investigate and close 80% of those alerts on the fly and therefore have freed up time to do more meaningful hunting or automated responses when it comes to inside jobs. ### 23. Very powerful for threat detection with exceptional accuracy as they emerge **Rating:** 5.0/5.0 stars **Reviewed by:** Nelson W. | Cyber Security Incident Responder, Mid-Market (51-1000 emp.) **Reviewed Date:** December 05, 2025 **What do you like best about GreyNoise?** GreyNoise implements rigorous internet monitoring for anomalous activity detecting botnet operators and malware, classifying attack patterns in a hierarchy based on common vulnerability exploitation methods enabling implementation of targeted detection and response strategies based on observed attack mechanisms. **What do you dislike about GreyNoise?** Nothing really, I have no complains about GreyNoise it does what it promises and I think even better. **What problems is GreyNoise solving and how is that benefiting you?** It has blocked countless threats and attempts to access our network and we are able to pinpoint which systems face ongoing exploitation and therefore we prioritize patching based on actual exploitation evidence rather than just CVSS scores. ### 24. GreyNoise: My Favorite Tool for Boosting Threat Intelligence **Rating:** 4.5/5.0 stars **Reviewed by:** Abhinav S. | Senior Project Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** August 11, 2025 **What do you like best about GreyNoise?** What I love most about GreyNoise is that it really does cut through the noise. Instead of drowning in endless alerts, it actually just reveals which IPs are just scanning the internet and which ones to really pay attention to. Its speed and accuracy have saved me so many hours; it would take a whole day to trace what often turned out to be false leads. Being able to act without leaping between platforms means I can immediately act, not leap. **What do you dislike about GreyNoise?** Sometimes, the interface feels a little cramped, and I wish some of the text was more readable without zooming in. I’ve also run into rare situations where an IP lookup took longer than expected during peak hours. An export feature for richer offline analysis would make my life even easier. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise has completely changed how I approach incident triage. Instead of manually reviewing every suspicious IP from my logs, I can instantly filter out the harmless background noise of the internet. I’ve used other intel feeds in the past, but none have been this effective at separating signal from noise while still integrating so well into my existing workflows. ### 25. Efficient IP tagging detecting every threat to create impenetrable firewall **Rating:** 5.0/5.0 stars **Reviewed by:** Azahar M. | IT Security Operations Head, Mid-Market (51-1000 emp.) **Reviewed Date:** November 03, 2025 **What do you like best about GreyNoise?** The tagging system is very useful for grouping sets of unwanted IPs and therefore we are able to distinguish between benign and malicious traffic. It saves a lot of time by helping us prioritize real risks instead of bots and this also greatly reduces threat alert fatigue. **What do you dislike about GreyNoise?** I find GreyNoise works very well for our company, and in my opinion, it completely ensures my security on the internet so nothing to dislike at the moment. **What problems is GreyNoise solving and how is that benefiting you?** Provides us with an early warning system on what is happening on the internet with actionable threat intelligence feeds that has helped us safeguard our network connections from security risks and cyber threats. ### 26. Efficient Threat Analysis with GreyNoise, but Interface Can Be Crowded **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Mid-Market (51-1000 emp.) **Reviewed Date:** October 16, 2025 **What do you like best about GreyNoise?** I mainly use GreyNoise to understand whether the strange traffic hitting our servers is anything to worry about or just some random internet traffic that isn't malicious or harmful to us. And when I’m checking firewall logs using GreyNoise, I can instead of running down each and every IP, I can determine very quickly what the benign scanners are versus the suspicious ones. **What do you dislike about GreyNoise?** Sometimes when I am tracking a very particular or new attack pattern I notice that data has not propagated everywhere and need to confirm manually. And the interface can also feel a little crowded when I’m filtering lots of queries at once which is particularly annoying on smaller screens. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise helps me filter out the unnecessary traffic and significantly speeds up my investigative workflow and as a result I have to spend less time checking false positives and more time patching real security issues. So in other words, it keeps our alert system sane and my day from being a mess from all the unnecessary internet traffic. ### 27. GreyNoise is my go-to for keeping email threats under control with precision and reliability. **Rating:** 4.0/5.0 stars **Reviewed by:** Milind N. | Vice President of Sales and Recruiting, Enterprise (> 1000 emp.) **Reviewed Date:** July 30, 2025 **What do you like best about GreyNoise?** I really like how GreyNoise helps me filter out phishing and malware-laden emails before they even hit my users’ inboxes. It has great impersonation protection that catches spoofed “CEO fraud” attempts that I’ve seen bypass other tools. I also like the Data Loss Prevention capabilities because they have stopped me from accidentally leaking information more than once. After the initial setup, it has essentially run itself, which has allowed me to concentrate on bigger IT jobs. **What do you dislike about GreyNoise?** It can be a little too severe with filtering URLs and domains, marking real links as suspicious. I’ve had a few users complain about having to resend documents after emails were mistakenly blocked. The admin dashboard is powerful but not the most intuitive, so I had to spend some time figuring out how to set policies correctly. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise has cut down on the number of phishing, malware, and spam emails that my team gets by a lot. It’s also cut down on distractions since we don’t get as many unsolicited emails interrupting our workday. I feel much more in control and at ease knowing that I can look into suspicious emails before sending them. Compared to alternatives like Mimecast and Proofpoint, I’ve found GreyNoise’s combination of threat detection and user flexibility strikes a good balance for my law firm’s security needs. ### 28.

Exceptional Threat Monitoring and Analysis—GreyNoise Sets the Standard **Rating:** 5.0/5.0 stars **Reviewed by:** Jackson M. | Information Systems Analyst, Mid-Market (51-1000 emp.) **Reviewed Date:** October 26, 2025 **What do you like best about GreyNoise?** It has powerful monitoring capabilities useful in threat identification and enables me to create alerts for specific domains and ISP to identify any kind threat or anomalies running on the internet. It efficiently monitors the log activities and gives results to any queries at faster speed than most threat intelligence tools. **What do you dislike about GreyNoise?** I haven’t had a bad experience, GreyNoise is the best in the field of emerging threat intelligence with great threat analysis combined with log analysis and deep search pattern. **What problems is GreyNoise solving and how is that benefiting you?** With this, we have been able to detect and react in a timely manner to those events that represent possible threats to our systems and devices. ### 30. Highly effective at maintaining clean internet usage and IP incident tracing **Rating:** 5.0/5.0 stars **Reviewed by:** Justus N. | Senior Executive Information Technology, Mid-Market (51-1000 emp.) **Reviewed Date:** October 30, 2025 **What do you like best about GreyNoise?** I needed detailed multiple IP analysis and security events reports which I found usefully equipped in this product. I am able to get sufficient information concerning erroneous domains. This consolidation eased the supervisory challenges of monitoring our network infrastructure. **What do you dislike about GreyNoise?** The product is very reliable although on a few occasions it took more time to load than usual because of the large volume of data regarding IP history. **What problems is GreyNoise solving and how is that benefiting you?** I am able to distinctively locate suspicious websites and misused protocols, and by linking security incidents to emergent threats we stop attackers trying to infiltrate our network and maintain the required standards for our infrastructure security. ### 31. Not every alert needs my attention—GreyNoise helps me figure that out. **Rating:** 5.0/5.0 stars **Reviewed by:** Jeremy P. | Vice President of Sales, Mid-Market (51-1000 emp.) **Reviewed Date:** July 21, 2025 **What do you like best about GreyNoise?** What I love about GreyNoise is the peace of mind. It’s like having a digital bouncer that tells you which IP is all talk, shouting at every door, and which one is really trying to pick your lock. There were so many times I’d chase down an alert only to find it was some mass scanner wasting my time. Once we brought GreyNoise into our stack, the false positives dropped dramatically. It's kind of like ThreatLocker in that “default deny” mindset except it’s not blocking executables but does block out distractions. **What do you dislike about GreyNoise?** There is a learning curve for sure, especially at the beginning when you are still trying to sift through what is noise and what is the signal. I’ve had juniors look at a flagged IP and totally panic, only to come back later and see that GreyNoise had this thing tagged as a known scanner for months. And, multiple approvals ala ThreatLocker, sometimes, a little more hand-holding in explanations of classification decisions would do me good from GreyNoise. **What problems is GreyNoise solving and how is that benefiting you?** Before GreyNoise, we were treating every port scan or every brute-force attempt as if it was the inauguration of a nation-state attack…like total reacts to everything that comes their way. Now, it's a reality filter. Instead of generic noise, we can home in on actual threats—malicious behavior being orchestrated specifically against us, that and us alone. It is not only a time saver but a sanity saver for the team. And sure, other tools may give wider intelligence, but GreyNoise gives focused, actionable clarity; and that's worth way more to me than a fancy dashboard with 500 red alerts. ### 32. Robust solid defense against internet phishing sites and exploitation traffic **Rating:** 5.0/5.0 stars **Reviewed by:** Titus G. | SOC Specialist, Small-Business (50 or fewer emp.) **Reviewed Date:** October 28, 2025 **What do you like best about GreyNoise?** Very good at IP classification changes giving us immediate notice when an IP flips state, such as from unknown to malicious. The detection rate in detecting sites engaged in malicious activities is one of the highest because of its real time threat assessments. **What do you dislike about GreyNoise?** There is no any issue with its functionalities but it has some advanced settings that take some time to configure to achieve a robust scan by event type. **What problems is GreyNoise solving and how is that benefiting you?** The platform reliably detects threats, alerts us right away and this enables us to apply correction capabilities and change security controls. This effectively saves workstations from threats and malicious attacks. ### 33. Comprehensive and Actionable Threat Intelligence with GreyNoise **Rating:** 4.0/5.0 stars **Reviewed by:** Sam A. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** July 14, 2025 **What do you like best about GreyNoise?** What I personally love about GreyNoise is that it feels like having a filter for internet junk traffic—something I didn’t realize I needed until I used it. Before GreyNoise, I wasted hours chasing random IPs scanning my network, only to find out they were harmless internet background noise. Now, my dashboard shows me what actually matters, and honestly, that’s saved my sanity more than once during a hectic day. **What do you dislike about GreyNoise?** What frustrates me sometimes is when the same type of alerts clutter my screen repeatedly, especially during scanning spikes. I’ve also noticed it struggles a bit when integrating with some of our older tools—we had to write custom scripts just to get things talking properly. And like every tool, it’s not perfect at filtering false positives—domain registration alerts especially feel like a recurring headache. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise solved a problem I didn’t even know I had: wasting time on background noise that wasn’t a real threat. It lets me focus only on what’s actually targeting us, whether that’s compromised IPs or bots acting strangely, and that has genuinely made me more productive. Compared to tools like SOCRadar, which throws a ton of data at me, GreyNoise feels like someone quietly whispering, “Ignore that, focus here”—and that’s invaluable when your day is full of real threats. ### 34. Exceptional IOC Tagging, Needs Better CVE Insights **Rating:** 4.5/5.0 stars **Reviewed by:** Shiv T. **Reviewed Date:** January 05, 2026 **What do you like best about GreyNoise?** I use GreyNoise for IOC tagging, which is top-notch and helpful in real-time blocking or blacklisting. It assists me in uncovering threat actors' other related infrastructure. The insights provided about threat activity are very helpful. I appreciate their awesome blogs and how GreyNoise helps in writing effective detection rules. The initial setup was trivial and direct. GreyNoise offers more comprehensive threat intelligence data than other tools I have used. **What do you dislike about GreyNoise?** The CVE database needs to have more insight, like Feedly. **What problems is GreyNoise solving and how is that benefiting you?** With GreyNoise, I effectively use IOC tagging for real-time blocking, uncovering threat actors' infrastructure, gaining valuable threat insights, and improving detection rules. ### 35. GreyNoise for the best immune against internet threats and complete security assurance **Rating:** 5.0/5.0 stars **Reviewed by:** Shadrack Y. | Network Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** November 10, 2025 **What do you like best about GreyNoise?** It provides us with a central dashboard where we classify malicious websites and get detailed context on IP addresses that scan and attack the internet helping us effectively identify risky breaches and apply rigorous protection that block threats to protect our network. **What do you dislike about GreyNoise?** I haven’t experienced any downside when using it since it’s very possible to secure our organization network from threats using this tool. **What problems is GreyNoise solving and how is that benefiting you?** Protects our devices and databases from malicious remote code execution therefore helping ensure that our data is not leaked and enabled us in mitigating network threats. ### 36. GreyNoise: Zero-Trust Reinvented for Real-World Security **Rating:** 5.0/5.0 stars **Reviewed by:** Ankur M. | CEO, Mid-Market (51-1000 emp.) **Reviewed Date:** June 29, 2025 **What do you like best about GreyNoise?** What I appreciate most about GreyNoise is how it takes a fundamentally different approach to threat intelligence—it filters out the noise of opportunistic internet scanning, so I can focus only on what truly matters. The concept of identifying "internet background radiation" makes our security stack so much sharper and more efficient. I can easily go from notifications to actionable intelligence, and it works well with the tools I already have. **What do you dislike about GreyNoise?** There is a learning curve initially—especially when trying to understand how to correlate GreyNoise's intelligence with our own alert data. I’ve also found that while the UI is improving, it could be more intuitive for newer analysts who aren't as familiar with interpreting internet scanner data. Sometimes the context is a bit technical unless you're deep in network security. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise saves us from wasting time chasing alerts caused by mass scanning bots or irrelevant background traffic—it acts like a reality check before incident response. As someone who’s worked with endpoint tools like ThreatLocker and firewalls that operate on default-deny principles, GreyNoise complements that by giving us the why behind certain traffic, not just the what. Compared to traditional threat feeds that throw too much at you, GreyNoise helps us prioritize, stay proactive, and avoid unnecessary escalations. ### 37. Effective smart analysis of the internet to enhance firewall governance **Rating:** 5.0/5.0 stars **Reviewed by:** Zain T. | Senior IT Support Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** October 30, 2025 **What do you like best about GreyNoise?** Very reliable at capturing comprehensive traffic logs to find suspicious activity on the internet with good IP filtering and the ways of dealing with threats are straightforward to a quick resolution. **What do you dislike about GreyNoise?** There is no area that raises negative functionality for me, and it has proved to be useful in assisting me to identify internet anomalies. **What problems is GreyNoise solving and how is that benefiting you?** It is very useful in helping head off any network security threats, blocking websites that are likely to cause traffic congestion and make it easier to spot other signs of intrusion from IP addresses. ### 38. Helps me focus on real threats, not just random internet issues and noises **Rating:** 4.0/5.0 stars **Reviewed by:** Ian B. | Chief Technology Officer, Small-Business (50 or fewer emp.) **Reviewed Date:** June 26, 2025 **What do you like best about GreyNoise?** GreyNoise is like Cloudflare's lesser-known cousin, but with a superpower—it tells me when I don’t need to worry. I love how it filters out background internet noise, so I’m not chasing false threats or wasting hours investigating harmless scans. It makes it easy for me to tell right away if IPs are visiting my servers and if they are crawlers or real bad actors. The interface is clean, and integrating with SIEM tools is surprisingly straightforward. **What do you dislike about GreyNoise?** Pricing can be hard to figure out especially if you're a small team or an indie developer or even if you're a medium size business. Some of the deeper analytics and tagging feel locked behind paywalls that should be more accessible. Also, like Cloudflare, support responsiveness can be hit or miss unless you're on a higher-tier plan. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise helps me cut through the noise—literally. Before using it, I used to waste a ton of time reacting to basic internet-wide scanners thinking they were targeted attacks. It has sped up and improved my threat triage, especially when combined with Cloudflare's WAF and rate restriction. They have worked together to cut down on false positives by a lot, which lets me focus on genuine threats that matter. ### 39. Intuitive Threat Analysis, Powerful Protection—Could Be Faster with JSON Files Analysis **Rating:** 5.0/5.0 stars **Reviewed by:** Charles N. | Operational Technology Analyst, Small-Business (50 or fewer emp.) **Reviewed Date:** October 23, 2025 **What do you like best about GreyNoise?** I can manage all of the open threats to my devices in one intuitive dashboard and it is quite successful in preventing malicious website pop-windows and malware which helps a lot counter cyber attacks. **What do you dislike about GreyNoise?** It is a very powerful tool. I really like it, however, if I could say anything, it could be even faster in analyzing uploaded JSON files. **What problems is GreyNoise solving and how is that benefiting you?** It ensures security of our private communication network inside our company and protects all internet work ensuring we do our jobs without fear of cyber damage to computers and file systems. ### 40. Accurate threat monitoring to only access compliant internet traffic **Rating:** 5.0/5.0 stars **Reviewed by:** Ravindra T. | IT Analyst, Mid-Market (51-1000 emp.) **Reviewed Date:** November 02, 2025 **What do you like best about GreyNoise?** I appreciate how it helps us monitor any spoofing made to domains and track IP configuration changes which has been very accurate in helping us to avoid malicious internet traffic. **What do you dislike about GreyNoise?** There are few times I have experienced poor response time while analyzing a large volume of log data subset. **What problems is GreyNoise solving and how is that benefiting you?** Looking through logs and events makes it easier to monitor security and network compliance across multi-vendor environments helping us quickly spot phishing attempts, prevent data breaches, and ensure traffic aligns with our acceptable use policies. ### 41. Great reliability in containing malware outbreaks through real time internet scan **Rating:** 5.0/5.0 stars **Reviewed by:** Mark N. | Security Assessment Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** November 05, 2025 **What do you like best about GreyNoise?** Incredibly powerful and intelligent in threat detection, uses a bare minimum of system resources, and very effective at tagging IP addresses that have been observed sending web requests that contain out-of-band interaction domains. **What do you dislike about GreyNoise?** Although network monitoring is very effective, there is some room for improvement in terms of graph interpretation. **What problems is GreyNoise solving and how is that benefiting you?** Informs us of latest malware with overall visibility on IP addresses and with this information we are able to perform very actual and robust security configurations on our servers and computers. ### 42. It is a must have tool for companies who value security without much complexity. **Rating:** 4.5/5.0 stars **Reviewed by:** Lucas S. | Software Developer, Small-Business (50 or fewer emp.) **Reviewed Date:** June 17, 2025 **What do you like best about GreyNoise?** What I love most about GreyNoise is how deeply it analyzes unknown programs without overwhelming me with unnecessary data—something that I find lacking in other tools. Its interface is clean, and I don't need to spin up a VM or sandbox just to get basic threat context. Compared to verbose platforms like some alternatives, GreyNoise gives actionable insights with minimal friction. **What do you dislike about GreyNoise?** That said, I wish GreyNoise provided more information about some artifacts—it occasionally feels like I need to do extra research elsewhere to fully understand what’s being flagged. Also, the free tier can feel limiting; sometimes I hit scan limits due to accidental interruptions or repeat submissions. A more transparent or flexible quota model would be appreciated. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise has drastically reduced the time I spend on initial triage, which is critical when you’re flooded with alerts. Before, I’d manually cross-check YARA rules and hash matches across several platforms—now, I rely on GreyNoise to surface threat intelligence in near real time. As someone learning deeper aspects of malware behavior and cybersecurity, tools like GreyNoise don't just help me work—they help me learn. ### 43. Reliable Context for IP Analysis with Small UI and Workflow Frictions **Rating:** 4.0/5.0 stars **Reviewed by:** Vinayak S. | Program Manager, Enterprise (> 1000 emp.) **Reviewed Date:** June 17, 2025 **What do you like best about GreyNoise?** What I like most about GreyNoise is how it helps me quickly differentiate between harmless internet noise and potentially targeted activity. The interface is clean and easy to navigate, which makes searching IPs and reviewing context very straightforward. I especially appreciate the rich metadata they provide on noisy IPs, things like classifications, tags and historical activity make it easier to decide whether something is worth investigating further. Their visualizations, like timelines and tag breakdowns, give a helpful snapshot without needing to dig through raw logs. I use it regularly to support incident investigation and reduce alert fatigue, and it definitely helps save time by filtering out irrelevant traffic. **What do you dislike about GreyNoise?** While GreyNoise is incredibly helpful for filtering out irrelevant noise from internet background traffic, there are a few areas that could improved. One challenge I face is that the data granularity sometimes feels a bit limited when I'm trying to investigate a specific pattern or need more context around an IP's behavior. Additionally, the search interface could be more flexible when handling bulk queries or custom filters. Lastly, while their enrichment is solid, deeper integrations with other security tools I use daily would help streamline the investigation process even more. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise helps solve the constant problem of distinguishing legitimate threats from noisy background internet scans or irrelevant traffic. In my role, we receive a high volume of security alerts, and not all them deserve deep investigation. GreyNoise helps me and my team quickly determine whether an IP is part of widespread internet scanning or something more targeted. This reduces the time spent chasing false positive, improves our team's efficiency, and allows us to focus our energy on incidents that actually matter to our infrastructure. It's also useful for validating whether certain activity requires blocking or further escalation. ### 44. GreyNoise knows what’s just noise and that’s exactly what I needed **Rating:** 4.0/5.0 stars **Reviewed by:** Nishant K. | Lead Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** June 11, 2025 **What do you like best about GreyNoise?** What I like most about GreyNoise is how it filters out internet "background noise" so I can focus on real, targeted threats. It drastically lowers alert alerts by marking various scanners and useless traffic, therefore cutting through the noise. I love the simplicity of the dashboard — I can investigate IPs in seconds and get enriched context like actor behavior, scanning patterns, and intent. It saves me hours every week that I used to spend manually triaging false positives. **What do you dislike about GreyNoise?** Some of the tags could be a bit more descriptive, especially for newer or low-confidence IP classifications. Occasionally, I find there's a lack of historical context for some behaviors, making it harder to assess long-term risk trends. I wish it had tighter integration with some niche or legacy tools we still rely on internally. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise helps us solve the problem of alert overload by identifying noise we can safely ignore — something no other tool does as well. Before using it, we were burning time chasing irrelevant alerts from scanners or commodity malware. Now, we can rapidly target threats that are actually targeting our assets and this shift has strengthened our proactive defense posture, improved SOC efficiency, and drastically reduced the time to respond to true incidents. ### 45. Impressive in controlled web access and tight in blocking malicious traffic **Rating:** 5.0/5.0 stars **Reviewed by:** Newton M. | Site Reliability Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** October 28, 2025 **What do you like best about GreyNoise?** It has been a solid tool for keeping my internet use secure and filtered. I like how it reliably blocks harmful websites and I am pleased with the IP filtering function. **What do you dislike about GreyNoise?** No issues so far, it’s been great. The thoroughness of the platform in threat detection is just amazing. **What problems is GreyNoise solving and how is that benefiting you?** It effectively blocks malicious and inappropriate sites, enhancing our network security. It completely eliminated the few spoofing issues we had and now only approved sites are enabled across all our offices. ### 46. GreyNoise is a really useful tool for threat intelligence and it has a proactive edge too **Rating:** 4.5/5.0 stars **Reviewed by:** Max B. | Senior Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** June 05, 2025 **What do you like best about GreyNoise?** GreyNoise is like a flavored stream of insights for the respective industry it serves and as a banking cybersecurity person, I love that it lets me focus only on things that matter and not general noise. The context details, whether it is leaked credentials, malware signatures, or APT tracking, are very detailed and often correlated with clear visuals and graphs which help us connect the dots quickly. **What do you dislike about GreyNoise?** While the intelligence is high quality, the UI feels a bit scattered and important information sometimes takes a few extra clicks to locate. There have been times the portal was sluggish, especially during large queries. Also, some threat actor updates feel delayed or surface-level, particularly when compared to niche feeds we use for Vietnam specific data. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise helps us proactively monitor for leaked information, compromised credentials, and brand abuse and before these threats can escalate. And also the automated hunting rules and alerts keep our soc ahead of real time threats, especially across the dark web and various forums. Compared to other TI platforms we’ve trialed (like Recorded Future or IntSights), GreyNoise feels more focused and less bloated, delivering what matters without overwhelming us with fluff. ### 47. I stopped worrying about security thanks to GreyNoise **Rating:** 4.0/5.0 stars **Reviewed by:** John S. | Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** June 04, 2025 **What do you like best about GreyNoise?** I find GreyNoise very appealing since it aligns with the real way I use my devices, especially as a person who signs up on lots of new websites, learns Python, and downloads scripts and datasets from all over the web. It’s not just some background AV application, but actively filters out those fishy ips, secures my inbox and keeps an immaculate work zone without me having to look for spam. **What do you dislike about GreyNoise?** GreyNoise makes it way too often to enforce me legitimate tasks without letting me know why like downloading code snippets or tools that I really need, which is the biggest issue I run into. On several occasions, it has even hung my machine post-upgrades, which can be quite irritating when I am in the middle of focused work or online classes. Honestly, the sheer number of features and the fairly steep learning curve initially left someone not working in a large IT department feeling a bit lost. **What problems is GreyNoise solving and how is that benefiting you?** I heavily rely on GreyNoise. It gives me confidence while exploring the web for coding resources, signing up on platforms with my email, running Python scripts, and not constantly worrying about getting phished or infected. Automated investigation and remediation features are like a second brain presence that reacts to threats faster than I ever could and has come to my rescue more than once. ### 48. GreyNoise is a smart ally for smarter threat detection **Rating:** 5.0/5.0 stars **Reviewed by:** Piyush S. | Chief Operating Officer, Mid-Market (51-1000 emp.) **Reviewed Date:** June 03, 2025 **What do you like best about GreyNoise?** GreyNoise's approach of stopping attacker strategies even before they reach our firewall truly appeals to me and their threat intelligence is quick and proactive, like an always scanning early warning system. The tailored notification tools also help us to remain informed and so even during periods of heavy traffic or suspected activity spikes, performance has been always steady. **What do you dislike about GreyNoise?** GreyNoise lacks native remedial or reaction mechanisms, hence we still depend on other tools for follow-up measures. For several of my junior analysts, the learning curve for API-based customizing was really steep. Although the main functionality is excellent, a more thorough dashboard would speed data understanding. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise helps us sort out random noise such as bot scans and crawlers and this usually used to clutter our SIEM and slow down our inquiries. But now we have faster triage and less team fatigue resulting from that noise decrease directly. GreyNoise keeps us concentrated on what really counts by functioning as a sanity filter for online traffic. ### 49. GreyNoise helps us cut through any unnecessary noise and focus on real cyber threats **Rating:** 5.0/5.0 stars **Reviewed by:** Sergey G. | Frontend Developer, Mid-Market (51-1000 emp.) **Reviewed Date:** June 01, 2025 **What do you like best about GreyNoise?** GreyNoise's ability to separate benign from malicious internet traffic stood out to me the most since it will enable my team to greatly reduce false alarms. It just fits right in without much overhead, hence I truly enjoy how effortlessly it interacts with our server and current SIEMs and SOARs. My particular preference is the tagging feature; grouping undesired IP addresses greatly facilitates analysis. Even during high-stress danger assessments, the simple UI facilitates navigation. **What do you dislike about GreyNoise?** Although I'm good with the price, I could understand how smaller security teams or startups with tighter budgets would find it overly costly. For testing, the free tier is useful; yet, its limitations can soon cause a bottleneck. GreyNoise is more of a potent booster than a single defense mechanism; it does not offer a whole security solution on its own either. **What problems is GreyNoise solving and how is that benefiting you?** GreyNoise greatly lowers the noise produced by background internet traffic and automated scanners, which used to exhaust much of our time and effort. And the smoothness and dependability of our vulnerability management processes have come from the API connectivity. We have experimented with different tools, but none of them help GreyNoise in terms of time saving and honing our attention on actual hazards. ### 50. help me to focus on real threats. **Rating:** 5.0/5.0 stars **Reviewed by:** James S. | Network Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** May 22, 2025 **What do you like best about GreyNoise?** Greynoise is great for getting rid of all the spam alerts. It's like it knows the difference between a real threat and the noise on the internet. It works well with my other tools, so I didn't have to make many changes to use it. The real-time information is great; it helps me find bad things quickly. I also feel like I can trust the facts. **What do you dislike about GreyNoise?** It's not great. I wish I had more control over the platforms to make them work better for my team. Also, it's not easy to understand at first. The guides work, but they could be easier for people like me who are just starting out. It misses some information on strange threats, so I have to look around on my own. **What problems is GreyNoise solving and how is that benefiting you?** Some alerts were useful, but my team got a lot of them before. greynoise fixed that by showing us what's important. stop following up on fake threats! It's saved us a lot of time and made it easy to look for problems. Our main goal now is to keep our network safe without any more stress. - [View GreyNoise pricing details and edition comparison](https://www.g2.com/products/greynoise/reviews?page=2§ion=pricing&secure%5Bexpires_at%5D=2026-07-14+13%3A20%3A50+-0500&secure%5Bsession_id%5D=31d0fa3a-e9b9-46fe-8081-190379f9b31f&secure%5Btoken%5D=578b9dd2e5e376bd8354067f47e8f2970a2663e2cfa5cf1c47f01aaff7b19585&format=llm_user) ## GreyNoise Integrations - [Airtable](https://www.g2.com/products/airtable/reviews) - [Apollo.io](https://www.g2.com/products/apollo-io/reviews) - [AWS Security Hub](https://www.g2.com/products/aws-security-hub/reviews) - [Copilot](https://www.g2.com/products/copilot-copilot/reviews) - [Dropzone AI](https://www.g2.com/products/dropzone-ai/reviews) - [FortiSOAR](https://www.g2.com/products/fortisoar/reviews) - [IBM QRadar SIEM](https://www.g2.com/products/ibm-ibm-qradar-siem/reviews) - [Jira](https://www.g2.com/products/jira/reviews) - [Notion](https://www.g2.com/products/notion/reviews) - [Papermark Virtual Data Room](https://www.g2.com/products/papermark-virtual-data-room/reviews) - [ServiceNow IT Service Management](https://www.g2.com/products/servicenow-it-service-management/reviews) - [Slack](https://www.g2.com/products/slack/reviews) - [Splunk Enterprise](https://www.g2.com/products/splunk-enterprise/reviews) - [suricata](https://www.g2.com/products/suricata/reviews) - [Webex Events & Webinars](https://www.g2.com/products/webex-events-webinars/reviews) ## GreyNoise Features **Orchestration** - Asset Management - Security Workflow Automation - Deployment - Sandboxing **Information** - Proactive Alerts - Malware Detection - Intelligence Reports **Personalization** - Endpoint Intelligence - Security Validation - Dynamic/Code Analysis **Generative AI** - AI Text Summarization - Generate Attack Scenarios - Generate Threat Detection Rules - Generate Threat Summaries **Agentic AI - Threat Intelligence** - Autonomous Task Execution - Multi-step Planning - Proactive Assistance - Decision Making ## Top GreyNoise Alternatives - [Cloudflare Application Security and Performance](https://www.g2.com/products/cloudflare-application-security-and-performance/reviews) - 4.5/5.0 (595 reviews) - [CrowdStrike Falcon Endpoint Protection Platform](https://www.g2.com/products/crowdstrike-falcon-endpoint-protection-platform/reviews) - 4.6/5.0 (417 reviews) - [Recorded Future](https://www.g2.com/products/recorded-future/reviews) - 4.6/5.0 (225 reviews)
