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]

Tenable Security Center identifies and prioritizes vulnerabilities based on risk to a business and is managed on premises. Tenable Security Center provides an automated approach to implementing and maintaining many technical controls included in an Information Security Management System based on ISO/IEC 27001/27002 standards. Tenable Security Center collects data from multiple sensors to analyse vulnerability, threat, network traffic and event information. Tenable Security Center supports most technical controls prescribed in the NIST CSF, ISO/IEC 27002 and CIS CSC frameworks. Tenable Security Center provides active and passive monitoring of technical control status. Tenable Security Center audits configurations of many third-party products and analyses events generated by them to identify control weaknesses.[5][7]

Tenable One connectors combine data from third-party security tools. Tenable One connectors can ingest data from additional tools, internal systems, spreadsheets or files. Tenable offers several global hosting locations, depending on the product used. Tenable customers may request a specific geographic region prior to deployment. Tenable keeps customer data within the designated region, including backups. Tenable Identity Exposure uses additional Azure data center locations. Tenable supports regional failover and disaster recovery for its cloud-based services. Tenable targets an RPO and RTO of 48 hours for all cloud-based solutions.[1][2][3][5][8][9]
