Tenable: CEO History

Tenable Holdings, Inc. (NASDAQ: TENB) is the global leader in exposure management and vulnerability assessment, headquartered in Columbia, Maryland. Founded in 2002 by cybersecurity pioneers Ron Gula, Jack Huffard, and Renaud Deraison, Tenable revolutionized modern corporate risk defense by commercializing Nessus—the most widely deployed vulnerability assessment scanner in cybersecurity history. Today, Tenable has evolved far beyond traditional vulnerability scanning to pioneer the modern discipline of Exposure Management. Anchored by its flagship Tenable One Exposure Management Platform, the enterprise provides Chief Information Security Officers (CISOs) and security teams with unified visibility across the entire modern attack surface: IT infrastructure, cloud workloads, Active Directory identity systems, web applications, and operational technology (OT) industrial networks. Tenable serves more than 44,000 corporate and government organizations worldwide, including 65% of the Fortune 500 and more than 45% of the Global 2000. Under the leadership of Chairman and Chief Executive Officer Amit Yoran (former Director of the US National Cyber Security Division), Tenable generates approximately $800 million in annual revenue, delivering actionable cyber risk intelligence and helping global enterprises prioritize and remediate vulnerabilities before they can be weaponized by threat actors.

Tenable operates a subscription-based Software-as-a-Service (SaaS) and software licensing business model with predictable, high-visibility recurring revenue: (1) Tenable One Exposure Management Platform (~40% of new bookings), billed as an annual SaaS subscription scaled by the number of licensed assets across IT, cloud, identity, and OT environments; (2) Tenable Vulnerability Management (formerly Tenable.io) and Tenable Security Center (~45% of revenue), providing core vulnerability scanning, compliance auditing, and risk-based prioritization for corporate IT infrastructure; (3) Specialized Cloud and Identity Modules (~10% of revenue), securing public cloud entitlements (Ermetic technology) and Active Directory configurations (Alsid technology); and (4) Nessus Professional Licenses (~5% of revenue), sold as annual recurring desktop and server licenses to independent consultants, penetration testers, and small security teams. Tenable generates gross margins exceeding 77% and maintains high customer retention rates driven by deep integration into corporate risk compliance workflows.
