Tenable is the leading vulnerability management company, known for the Nessus vulnerability scanner which has been the industry standard for network vulnerability scanning for over 20 years. Its modern platform, Tenable One, applies AI to the challenge of prioritising which vulnerabilities to fix from the thousands that typical enterprise environments contain.
Vulnerability management without AI produces overwhelming lists of vulnerabilities ranked only by CVSS severity score. In practice, most organisations cannot fix all vulnerabilities and need to prioritise ruthlessly. Tenable's VPR (Vulnerability Priority Rating) is an AI-calculated score that combines CVSS severity with threat intelligence — whether a vulnerability has a known exploit, active exploitation in the wild, and other factors — to produce a prioritisation that reflects actual exploit risk rather than theoretical severity.
Exposure Graph, Tenable One's unified view, maps the attack paths from internet-accessible entry points through the internal environment to critical assets. Like Wiz's Security Graph for cloud, Exposure Graph identifies which vulnerabilities are on actual attack paths to sensitive systems, dramatically reducing the number requiring immediate attention.
Tenable AI (their Generative AI features) provides natural language queries of vulnerability data, AI-generated remediation guidance, and AI-powered attack path explanation — helping security teams who understand the risk but need clear remediation instructions to take action faster.
Tenable AI runs as ml platform software built around data and text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, agent, and api.
