About Censys

Censys continuously scans the public internet and turns that into an asset graph: certificates, services, devices, and the orgs behind them.

Security teams use it to find forgotten cloud, shadow IPs, and adversary infrastructure, not just to vanity-search their own /24. The 2026 round is explicitly to put AI workflows on top of that map.
