GreyNoise Reviews & Product Details

I use GreyNoise every day to cut down all the noise in my alerts. It quickly tells me if an IP is just a mass scanner or something I actually need to look into. This saves me hours that I used to waste on false positives. It is easy to set up, works smoothly with my existing tools, and the interface is simple to understand. I can cross check suspicious activity in seconds and focus only on real threats. The integrations with our security tools make the response process much faster.

A few advanced features are not easy to find, and occasionally it does not auto load data from our EDR, so I have to double check things myself. I would love clearer filtering options and maybe some AI features to help spot new threats faster. Review collected by and hosted on G2.com.

I am writing this as the air conditioning in our server room hums extremely loudly and is distracting. To be honest the sandbox did not crash on me when I was doing malware analysis which is good news since most of the tools I have worked with do and I have to restart everything. Also the summary output from the AI assistant is very readable and I no longer have to read through 100 logs which consumes a lot of time. Review collected by and hosted on G2.com.

The dark theme (dark mode) is always set back to bright white upon logging in and it is very frustrating so they should fix this bug as quickly as possible.The price point of this application is simply too high in comparison to what you receive and it appears that the developers broke the product into a number of different modules so they could charge you for each one individually. In addition it becomes extremely slow and cumbersome if you are trying to perform a series of complex or multi-query searches at once. Review collected by and hosted on G2.com.

GreyNoise helps me quickly tell whether strange traffic hitting our servers is harmless or something suspicious, so I do not waste time checking every IP in the logs. It gives fast results, lets me set alerts for certain domains or ISPs, and helps spot any unusual activity on the internet. It also cuts down a lot of false positives, like having a digital bouncer that filters out all the background noise. Review collected by and hosted on G2.com.

Some IPs do not have enough information, so I sometimes have to double check things myself. I also feel like certain parts of the interface could be a bit easier to navigate. Review collected by and hosted on G2.com.

Easy to use and allows us to carry out network vulnerability assessment at a low cost and in a flexible way. The process of uploading TXT, CSV, and PCAPNG files for analysis was quick and the IP reports are clear and concise. Provides great ability to create IP tags, set access policies and paste malicious IPs into our firewalls to block any future traffic from such unwanted IP addresses.

The product has no downsides or inconveniences in the use of it searching for vulnerabilities in our network and analyzing multiple IPs. Review collected by and hosted on G2.com.

The IP reports are easy to read after we perform a scan on multiple IPs to find out what is going on the internet. I do like that the dashboard is refreshed with the latest IP intelligence and it gives us the ability to build blocklists tuned precisely to our organization’s threat model so it automatically blocks malicious IPs and acts as our real-time firewall.

The product has been very reliable in its security capabilities and we have suffered no ill effects from any internet attacks. Review collected by and hosted on G2.com.

I like this tool because it always helps me identify network vulnerabilities by scanning IPs, hosting and ISPs making it easy to plan my security strategies and secure the network. The tool is very reliable in blocking attackers attempting to bypass web service API authentication controls which protects our data in transit from interception.

I have only had a good experience with this tool so far and there is nothing I see as an issue at this stage. Review collected by and hosted on G2.com.

I’m impressed by the easy installation of GreyNoise in our environment, it runs very smooth and finds all kinds of threats on the internet and is able to produce a graphical report that illustrates sequence of recorded events of multiple IPs performing network penetration attempts. It does a good job exposing all compromised ISPs across the internet and it has been our best tool to link vulnerabilities with patching. Review collected by and hosted on G2.com.

Nothing really I would say the experience is highly positive and I was impressed by how detailed the network analysis and vulnerability resolutions are. Review collected by and hosted on G2.com.

I truly appreciate how effortlessly GreyNoise integrates with other server security and authorized analysis tools, including firewalls. This smooth integration enables me to block and filter unwanted content, which not only enhances the overall security system but also helps ensure that my IT operations continue without interruption. I am also impressed by how quickly GreyNoise can be set up compared to other tools; this efficiency streamlines the integration process and allows me to prioritize setup tasks within a week. Furthermore, I value its compatibility with existing security systems, as it increases the effectiveness of threat analysis intelligence tools and something I consider vital for maintaining robust security operations. Security teams have the ability to configure alerts for specific IP addresses or ranges, making it possible to proactively identify potential threats without the need to manually sift through raw logs. GreyNoise collects data from a broad array of internet sources, monitoring traffic for suspicious or unusual activity. When an IP address is detected scanning or probing, it is promptly flagged and documented. Review collected by and hosted on G2.com.

I really appreciate how the support team stays connected with the user community, always making themselves available when needed. It's crucial for support staff to be actively involved, keeping an eye on community messages and responding quickly. This kind of engagement is especially vital when the community is missing information those are the times when the support team needs to step in right away to address concerns and ensure every issue is fully resolved.

I love that I can know right away that an alert is nothing to worry about, just the internet’s background noise. I use it multiple times a day to pull up the new IP addresses in my alerts and figure out whether it’s all coming from a massive, harmless scanning movement or if someone is really trying to target us. It keeps me from freaking out about stuff that doesn’t matter. Review collected by and hosted on G2.com.

It’s easy to use, but making it perfectly work in conjunction with all the different security tools we use took slightly more effort than I anticipated. And sometimes I feel like I should have clicked one more button to simply say don’t ever alert me on this kind of things, but that’s a small problem. Review collected by and hosted on G2.com.

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.

Providing more support documentation could be very helpful when we get an error and make it quicker to get to the correct answer. Review collected by and hosted on G2.com.
