No attack works twice

Today’s attackers mass scan the internet to exploit perimeter weaknesses. The same Tactics, Techniques and Procedures are repeatedly used to exploit countless organizations. Our sensors are patient zero for these attacks, collecting valuable telemetry in the interaction. We distribute this intelligence in near real-time with verifiable proof so that our customers can act quickly. Our mission is to ensure that no attack works twice.

How it works

The GreyNoise Platform

Collection

GreyNoise maintains a global fleet of thousands of sensors mimicking commonly used and exploited software. These sensors capture all traffic that interacts with them.

Analysis

This data is sent to the GreyNoise analytics engine in real-time, which classifies the intent of the activity and tags the data for easy querying and analysis.

Dissemination

The processed intelligence can be consumed through our API, our Visualizer portal, bulk data files, or directly by your security platforms via our integrations.
