About Tenable

Tenable was founded in 2002 and is still best known for Nessus, the vulnerability scanner. Its main product now is Tenable One, an exposure management platform with modules for vulnerability management, cloud, OT, identity, attack surface and web app scanning.

Tenable Security Center does the same job for teams that keep scanning on premises, and Tenable Patch Management takes care of the fixes.
