Tired of dealing with brute force attempts, web crawlers, and other scanners filling up your logs and trying to break into your infrastructure? With GreyNoise’s blocklists, you can prevent noisy scanners from hitting your perimeter, effectively shutting them out, and giving yourself time to patch when there is an emerging exploit.

Use cases

Using Blocklists

Blocklists are supported within our Tags pages, and adding a dynamic blocklist to your firewall is simple. From our Tag Details page, choose the Automated ‘Block At Firewall’ action to generate the Blocklist URL.  Integrate it with your next-generation firewall and you are protected!

Screenshots of the Actions panel on a Tag Details page in the GreyNoise Visualizer. Actions including downloading an IP list or blocking at a firewall.
