Tenable values


  • Cloud Security

Tenable delivers complete multi-cloud visibility and security, providing a unified view of vulnerabilities, misconfigurations and drift in a single pane of glass. Quickly prioritize action with risk-based scoring, compliance reporting and auto-remediations that speed Mean Time to Respond (MTTR) up to 99%.

  • Web App Security

Web applications are ubiquitous, business-critical and ever-changing. Tenable delivers easy-to-use, comprehensive and automated vulnerability scanning for modern web applications. Users can configure and manage web app scans and receive actionable results in minutes.

  • Active Directory Security

Behind almost every breach headline is an attack on Active Directory (AD) that allows the attacker to elevate privileges and facilitate lateral movement. Tenable enables users to see everything in their AD environment, predict what matters and address risks to prevent attack paths before attackers can exploit them.

  • Risk-based Vulnerability Management

Legacy vulnerability management (VM) tools are no match for today’s IT landscape. Risk-based vulnerability management takes the guesswork out of which vulnerabilities to tackle first.

  • External Attack Surface Management

Visibility is foundational to cybersecurity, yet few organizations have mastered it. External attack surface management (EASM) maps the entire internet and discovers all of your organization’s domains. Identify and secure previously unknown internet-connected assets to eliminate blind spots.

  • Operational Technology Security

Industrial digital transformation increases control, efficiencies, production and safety, but it’s not without risks. Tenable offers complete visibility, unified security and prioritization of threat management to help mitigate risk across an integrated IT and OT landscape.

  • Built on Nessus, the Gold Standard in Vulnerability Assessment

Understanding vulnerabilities is foundational to exposure management and Nessus is at the core of Tenable One. Helping users assess their modern attack surfaces, Nessus provides an accurate picture so users can work quickly and effectively.
