Vendor
Tenable Holdings, Inc. is a Columbia, Maryland-headquartered cybersecurity and exposure management company founded in 2002 by Ron Gula, Jack Huffard, and Renaud Deraison pioneering the Nessus vulnerability scanner (created 1998). The company serves 44,000+ global customers including 65% of Fortune 500 companies and 50% of Global 2000 organizations. With 1,200+ employees globally and $1.5B+ market capitalization (publicly traded on Nasdaq: TENB since 2018), Tenable leads the exposure management market with comprehensive platform addressing vulnerabilities, cloud security, identity exposure, and operational technology (OT) security. Company mission centers on empowering organizations to understand and reduce cybersecurity risk through unified visibility across entire attack surface. Tenable pioneered transition from vulnerability management to exposure management paradigm - addressing not just vulnerabilities but complete cyber exposure including risk context, business impact, and attack paths. Core differentiators include Nessus scanner industry dominance (gold standard for vulnerability assessment), Tenable Research threat intelligence, VPR (Vulnerability Prioritization Rating) risk-based prioritization, and modular product architecture enabling independent product selection. Strategic focus on AI-powered exposure management, attack surface visibility, and enabling security teams to prioritize and remediate only the exposures that truly matter (statistically only 3% of vulnerabilities represent actual business risk).
