Tenable Review: Features, Pricing & Integrations 2026
Trusted by 43k+ customers for its Nessus scanner, Tenable () lacks AI integrations like ChatGPT for deep risk analysis. Free tier available.
Expert Analysis of Tenable
Tenable is the Nessus company, the default scanner for vulnerability management across cloud, OT and identity. It runs a genuinely free Essentials tier, then meters the rest per licence or per asset. The catch: the cloud platform and Tenable One stay quote-only, and storefront prices are geo-localised.
Oleh KemFounder & Lead AnalystRisk-Based Vulnerability Prioritization by Asset Criticality
Tenable.io correlates vulnerability severity with asset criticality scores, surfacing the top 3% of vulnerabilities that pose real risk versus thousands of theoretical findings.
Active Directory Attack Path Analysis
Tenable Identity Exposure maps Active Directory misconfigurations to known attack paths like AS-REP Roasting, showing how attackers could escalate from a standard user to Domain Admin.
Continuous Assessment of External Attack Surface
Tenable Attack Surface Management discovers internet-facing assets not in the asset inventory, attributing orphaned domains and IP ranges back to the owning organization.
