About Us

Our Company

Tenable Network Security is at a transition in cybersecurity technology that will change the way companies protect their networks. Tenable started the revolution when one of its co-founders created the Nessus® vulnerability scanner, the first robust solution for detecting vulnerabilities that viruses and hackers can exploit. The Tenable platform has evolved into today's most powerful vulnerability and threat detection technology.

Our Mission

Tenable founders Ron Gula, Renaud Deraison, and Jack Huffard build technology that secures and protects any device from threats on the Internet – malicious software, hackers, viruses, and more. Tenable wants its customers and every company to have access to the latest and best technology that will ensure they stay connected, online, and in business.
