About
Tenable is a cybersecurity company founded in 2002 and headquartered in Columbia, Maryland, that pioneered the vulnerability management category and remains its global leader. The company was founded by Ron Gula and Jack Huffard around the Nessus vulnerability scanner, one of the most widely deployed security tools in the world, with a mission to help organizations understand and reduce their cyber exposure across their entire attack surface. Tenable's core conviction is that organizations cannot defend what they cannot see — and that comprehensive, continuous visibility into vulnerabilities is the prerequisite to effective security.\n\nTenable's platform portfolio includes Tenable.io (cloud-native vulnerability management), Tenable.sc (on-premises), Tenable OT Security (operational technology), Tenable Web App Scanning, Lumin (exposure-based risk scoring), and the Tenable One exposure management platform. The company serves enterprise and government customers globally with a product suite that covers cloud workloads, on-premises infrastructure, operational technology, and web applications. In February 2025, Tenable completed the $148 million acquisition of Vulcan Cyber, a risk-based vulnerability prioritization platform, expanding its capabilities in correlating vulnerability data with threat intelligence and business context.\n\nTenable reported trailing twelve-month revenue of $974.60 million as of 2025, up 11% year over year, and was named the number one worldwide vulnerability management vendor by IDC in 2024. The company trades on Nasdaq under the ticker TENB and competes against Qualys, Rapid7, and a growing set of cloud-native exposure management entrants. Its Nessus heritage, market leadership validation from IDC, and strategic expansion into broader exposure management through Tenable One and the Vulcan Cyber acquisition position it as the reference platform for enterprise vulnerability and exposure management.
