About GreyNoise Intelligence
GreyNoise Intelligence provides real-time network threat intelligence. It sells access to its platform and blocklists that help organisations detect and respond to attacks on edge devices. The company operates a global sensor grid that observes internet scanning and exploitation activity first-hand. This primary-source data is analysed to classify IP addresses as malicious, suspicious, benign, or unknown. Customers use this intelligence to block novel exploitation, find compromised devices, and speed up incident triage. The company serves government agencies, enterprises, and small to mid-sized teams. It offers products for different needs, including a platform for security operations centres and a blocklist tool for smaller teams. Its intelligence integrates with existing security tools such as SIEM, SOAR, firewalls, and WAFs. The company emphasises real-time updates and early warning of exploitation, often before public disclosure.
