Tenable is the cybersecurity company behind Nessus. Compare pricing, features, pros and cons of its vulnerability and exposure management platform.
Tenable is a cybersecurity company that builds vulnerability management and exposure management software used by security teams to find, prioritize, and fix weaknesses before attackers can exploit them. Its flagship product, Nessus, is one of the most recognized and widely deployed vulnerability scanners in the industry, used by security professionals, students, and enterprises alike.
Beyond Nessus, Tenable has expanded into a full exposure management platform called Tenable One, which unifies vulnerability data, cloud security posture, identity risk, and attack surface information so security teams can see and reduce risk across an entire organization rather than working from siloed tools.
Tenable's product suite spans network vulnerability scanning, cloud security posture management, web application scanning, container image scanning, identity exposure, and operational technology security. The underlying plugin library, maintained by Tenable Research, covers hundreds of thousands of known vulnerabilities and misconfigurations across operating systems, applications, and network devices.
Tenable One layers risk-based prioritization and attack path analysis on top of raw scan data, helping teams understand which vulnerabilities actually create exploitable paths to critical assets rather than treating every finding as equally urgent.
Tenable offers a free tier, Nessus Essentials, limited to scanning 16 IP addresses for personal, non-commercial use such as learning and small home labs. Nessus Professional, the standard paid edition for individual practitioners and small teams, is priced at approximately 4,790 dollars per year per scanner with no IP limits. Nessus Expert adds external attack surface and cloud scanning for around 6,790 dollars per year. Larger platform products such as Tenable One and Tenable.io are quoted with custom, usage-based enterprise pricing.
