Tenable.io Overview
What is Tenable.io?
Tenable.io (now offered as Tenable One Vulnerability Management) is a cloud-based, asset-focused vulnerability and exposure management platform. It combines active scans (Nessus sensors), agents, and passive monitoring to provide broad asset discovery (IT, cloud, OT/IoT, web apps and external attack surface), prioritization (VPR, exploitability, attack-path analysis), remediation guidance/workflows, and integrations across ticketing, SIEMs, cloud providers and identity systems. The product sits within the Tenable One exposure management suite and emphasizes predictive scoring and AI-assisted automation.
