"Great vulnerability detection power that leaves no escape to any threat"
5/5
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. Review collected by and hosted on G2.com.

"Helps Me See What Really Matters in Our Alerts"
4.5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

What do you dislike about GreyNoise?

Nothing really, I have no complains about GreyNoise it does what it promises and I think even better. Review collected by and hosted on G2.com.

"GreyNoise: My Favorite Tool for Boosting Threat Intelligence"
4.5/5
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. Review collected by and hosted on G2.com.

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.

"Efficient IP tagging detecting every threat to create impenetrable firewall"
5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"Efficient Threat Analysis with GreyNoise, but Interface Can Be Crowded"
5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"GreyNoise is my go-to for keeping email threats under control with precision and reliability."
4/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"Exceptional Threat Monitoring and Analysis—GreyNoise Sets the Standard"
5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"Highly effective at maintaining clean internet usage and IP incident tracing"
5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.
