What Is Tenable?
Tenable is a vulnerability management and exposure management company known for Nessus. Tenable's own purchase page, read directly, lists Nessus Professional at $4,790 for one year, $9,330.95 for two and $13,637.54 for three, with Advanced Support at $400 and On-Demand Training at $275. Nessus Expert is $6,790 for one year, $13,208.13 for two and $19,304.19 for three. Tenable One Vulnerability Management is $3,700 for a year up to 250 assets, with two and three years at $6,825 and $9,975, though a later modal on the same page shows $3,500 for one year, so those conflict. Web App Scanning is $6,790 for five FQDNs on the page and $3,578 in a modal. The page does not state the currency. Other products such as Exposure Management and Cloud Exposure are by customised quote, and free trials are offered for Tenable One VM, Web App Scanning and Nessus Professional.
AI is described rather than priced. Third-party sources describe Hexa AI as an agentic engine built on Tenable's Exposure Data Fabric, which suggests it is bundled into the platform, though that is an inference, and I found no ExposureAI results or Hexa AI pricing. Nessus Essentials is the free, non-commercial tier, with the IP cap reported as either 5 or 16. One aggregator estimates Tenable One deployments start around $50,000 a year. Because list prices and on-page figures conflict, get a quote and check the currency before ordering.
Tenable suits security and IT teams that need vulnerability scanning from a single scanner to enterprise exposure management. Compare Qualys, Wiz and Sysdig. Browse the Cybersecurity tools directory for more.
