Vulnerability management and exposure security
Tenable is a vulnerability management and exposure-security company best known for Nessus, the widely used vulnerability scanner, and Tenable Vulnerability Management (formerly Tenable.io), its cloud platform for identifying, prioritizing, and remediating security weaknesses across IT, cloud, and OT environments. It helps security teams understand and reduce their cyber exposure.
The platform scans assets for vulnerabilities and misconfigurations, prioritizes them by risk using threat intelligence, and tracks remediation, extending across the modern attack surface with Tenable One, its exposure-management platform. Nessus remains the industry-standard scanner for many practitioners, while the cloud platform adds continuous, scalable vulnerability management.
Tenable offers Nessus Essentials free for up to 16 IP addresses, Nessus Professional at around 4,790 dollars per year (unlimited targets from one scanner), Nessus Expert at around 6,790 dollars, and Tenable Vulnerability Management from around 3,700 dollars per year for up to 250 assets, with Tenable One quote-based from roughly 50,000 dollars for enterprises. Aimed at security teams and enterprises, it competes with Qualys, Rapid7, Snyk, Wiz, and CrowdStrike.
