About Tenable

Tenable sells Tenable One, a platform that unifies security visibility, insight and action across an attack surface. Tenable One uses native signals, exposure intelligence and third-party data to map the attack surface across infrastructure, cloud, identity, OT, third-party applications and AI. Tenable One connects potential risk with pathways for exploitation and impact through continuously enriched exposure intelligence. Tenable One unifies disparate security data to show how a weakness in one domain can escalate into a breach in another. Tenable Hexa AI is the agentic layer of Tenable One.[2][3]

Tenable One Vulnerability Management is built on Tenable Nessus technology and is managed in the cloud. Vulnerability Priority Rating (VPR) is powered by generative AI, enriched threat intelligence and context-aware scoring. Tenable unifies all vulnerability management data with continuous asset scanning and automated risk prioritization capabilities. Tenable supports bi-directional ticketing to mobilize remediation and benchmarking of progress. Tenable One discovers and continuously inventories assets across IT, cloud, OT, web applications and the external attack surface. Tenable One measures, compares and tracks exposure using risk scores and benchmarks. Exposure alerts from Tenable One can be integrated with manual or automated ticketing workflows for IT, cloud and security teams.[1][3][4][5]

Tenable cloud security addresses misconfigurations, risky entitlements and vulnerabilities across multi-cloud and hybrid environments. Tenable combines cloud workload protection (CWPP) with cloud security posture management (CSPM and KSPM).[2][4][5]

Tenable identity security uncovers weaknesses and overprivileged access in Active Directory and Entra ID. Tenable offers a unified security solution for converged OT/IT environments. Tenable continuously discovers AI tools, agents and workloads across an attack surface. Tenable discovers shadow AI, AI workloads, services and externally exposed AI components. Tenable identifies vulnerabilities and misconfigurations in AI workloads and supporting cloud infrastructure. Tenable provides visibility into employee use of generative AI and autonomous agents. Tenable detects and responds to AI-specific threats and misuse, including prompt injection and jailbreaks.[2][4][5][6]
