What Is Tenable?

Tenable offers security products for vulnerability management and broader exposure management across IT assets, cloud infrastructure, identity systems, operational technology, and attack paths. Its portfolio includes Tenable Vulnerability Management, Tenable Cloud Security, Tenable Identity Exposure, Tenable OT Security, and Tenable One, with technology partnerships connecting findings to SIEM, ticketing, cloud, and security operations tools.

Best for: Enterprise security and vulnerability teams that need asset exposure data across traditional infrastructure, cloud, identity, and operational technology.

Tenable vulnerability management collects asset information through scanning and other inventory sources, then supports tags such as location and operating system to segment remediation efforts. Dynamic tag rules can apply to matching devices instead of requiring a static host spreadsheet. Organizations can use these tagged groups to organize investigation of affected systems and assign security context to the inventory.
