Tenable One: CAASM and asset inventory facts (2026)
SHORT ANSWER
Tenable One is Tenable's exposure management platform: Tenable Attack Surface Management maps external assets from a 5 billion+ asset map, and Tenable One adds vulnerability data, attack path analysis and Hexa AI remediation. It suits teams standardising on Tenable. Attack Surface Management and the platform are demo only (free trials cover Vulnerability Management and Nessus), and a unified internal inventory, SaaS apps and identities are not described on the pages we read.
