Tenable Cloud Security

CIEM-led CNAPP built on Ermetic foundation.

By Tenable Holdings, Inc. · Founded 2002 · Columbia, MD · public

Tenable Cloud Security is the CNAPP product from Tenable (the Nessus / Tenable.io vulnerability management leader), built primarily on the October 2023 acquisition of Ermetic for $265M. The product's primary advantage: deepest CIEM (cloud infrastructure entitlement management) capabilities in the category, Ermetic was the leading CIEM-pure-play before the acquisition, and Tenable has retained that strength. Best fit for buyers leading with cloud identity governance and entitlement risk. Trade-offs: outside CIEM-led use cases the product is less compelling than Wiz / Orca, posture (CSPM) and runtime (CWPP) capabilities less mature than CIEM, and integration with broader Tenable vulnerability management is a work in progress. Public company financial transparency and breadth of customer base (Tenable serves 65% of Fortune 500) are meaningful differentiators.
