We collect, analyze, and label data on IPs that scan the internet and saturate security tools with noise. This unique perspective helps analysts spend less time on irrelevant or harmless activity, and more time on targeted and emerging threats.Discover your ROI
GreyNoise’s internet-wide sensor network passively collects packets from hundreds of thousands of IPs seen scanning the internet every day.
Companies like Shodan and Censys, as well as researchers and universities, scan in good faith to help uncover vulnerabilities for network defense. Others scan with potentially malicious intent. GreyNoise analyzes and enriches this data to identify behavior, methods, and intent, giving analysts the context they need to take action.
RIOT provides context to communications between your users and common business applications (e.g., Microsoft O365, Google Workspace, and Slack) or services like CDNs and public DNS servers. These applications communicate through unpublished or dynamic IPs, making it difficult for security teams to track. Without context, this harmless behavior distracts security teams from investigating true threats.
"Using GreyNoise Intelligence helps the Hurricane Labs team eliminate background noise and focus on the most actionable and relevant alerts for our customers. Rather than presenting our analysts with even more data to investigate, GreyNoise decreases the volume of alerts that are triggered by 25% - which makes for a happier and more effective SOC team."
"RIOT arms our analysts with a simple, colorized tool for surfacing enrichment details so the SOC can quickly spot and dispatch non-threat activity."
"GreyNoise has proved to be a high-bang-for-the-buck data source for alert triage. The team is motivated, innovative, and great to work with."
"GreyNoise helps our users reduce time to remediation by quickly pointing out noisy activity related to scanners, botnets or harmless business services—saving the analyst from chasing irrelevant deadends and leaving more time to investigate true threats."
