Tenable
Tenable (NASDAQ: TENB) is a publicly traded Email, AppSec & GRC company founded in 2002 and based in Columbia, United States.
Founded in 2002 as Tenable Network Security by Ron Gula, Jack Huffard, and Renaud Deraison, Tenable is built around Nessus, the widely deployed vulnerability scanner Deraison originally created in 1998. The company has expanded from vulnerability assessment into broader exposure management, adding cloud security, Active Directory security, operational-technology (OT) security, and risk-based prioritization analytics. Tenable went public on the Nasdaq under ticker TENB in 2018 and says it serves tens of thousands of customers worldwide, including a majority of the Fortune 500.
Tenable created the modern vulnerability scanner with Nessus and is now a leading public pure-play in exposure management, the discipline of continuously finding and prioritizing an organization's security weaknesses.
