Collect and analyze internet background noise to reduce false positives and identify compromised devices.


Most cyber security companies tell you all of the things you should be worried about.  GreyNoise tells you all of the things not to be worried about. Think of them as “anti-threat intelligence”.

GreyNoise collects and analyzes untargeted, widespread, and opportunistic scan and attack activity that reaches every server directly connected to the Internet. Mass scanners (such as Shodan and Censys), search engines, bots, worms, and crawlers generate logs and events omnidirectionally on every IP address in the IPv4 space. GreyNoise gives you the ability to filter this useless noise out.
