What is Tenable One?
Tenable One is an exposure management platform that finds vulnerabilities, misconfigurations and risky identities across IT, cloud and OT and ranks them by risk. It is aimed at IT and security teams that must decide what to fix first.
Tenable One combines vulnerability management, web application scanning, cloud security, identity exposure and OT security. Tenable is headquartered in Columbia, Maryland, and also sells the Nessus scanner. Smaller vulnerability management subscriptions can be bought online, larger ones through sales.
Tenable One AI features and use cases
- Ranks vulnerabilities by real riskThe Vulnerability Priority Rating uses machine learning models to estimate which vulnerabilities are most likely to be exploited. IT teams patch the most dangerous gaps first instead of working through long lists by severity alone.
- Automates follow-up workTenable Hexa AI is an agentic orchestration engine that turns exposure data into automated multi-step security workflows. Teams spend less time on repetitive steps between finding and fix, so define which steps may run without approval.
- Shows risks from AI toolsAI Exposure reveals how employees and agents use ChatGPT Enterprise and Microsoft Copilot, finds misconfigurations and detects attacks such as prompt injection. Security teams can enforce acceptable use policies.
What sets Tenable One apart
- Publishes entry prices online and offers free trials for vulnerability management and Nessus.
- AI Exposure supports ChatGPT Enterprise and several Microsoft Copilot products, but not the free ChatGPT version.
