GreyNoise Intelligence

GreyNoise is a cybersecurity company that analyzes Internet scanning traffic to separate threats from background noise.

GreyNoise is a source for understanding internet noise. The company collects, analyzes and labels data on IPs that scan the internet and saturate security tools with noise. This perspective helps analysts waste less time on irrelevant or harmless activity, and spend more time focused on targeted and emerging threats. GreyNoise’s internet-wide sensor network passively collects packets from hundreds of thousands of IPs seen scanning the internet every day. The platform can scan to analyze and enable data to identify behavior, methods, and intent, giving analysts the context they need to take action.

GreyNoise helps analysts recognize events not worth their attention. Indicators in GreyNoise are likely associated with opportunistic internet scanning or common business services, not targeted threats. This context helps analysts focus on what matters most. GreyNoise notifies analysts when an IP they care about shows up in our collection, helping security teams respond quickly to compromises. GreyNoie's security teams can uncover tradecraft seen across the internet through our GreyNoise Query Language (GNQL). Our tags reveal IPs looking for and exploiting vulnerabilities. Security teams can assess their exposure as they monitor progressive threat activity.
