Tenable Holdings, Inc., originally founded in September 2002 as Tenable Network Security, Inc., is a prominent global cybersecurity software company headquartered in Columbia, Maryland. The company was co-founded by Ron Gula, Jack Huffard, and Renaud Deraison. Deraison famously created the Nessus vulnerability scanner software in 1998 at the age of 17, which subsequently became the foundational technology and brand anchor for Tenable upon its inception. Today, Tenable has evolved significantly from its roots as a strong vulnerability scanning vendor into a comprehensive, AI-powered exposure management platform provider. The company's primary corporate mission focuses on exposure management, aimed at helping organizations see, prioritize, and reduce cybersecurity risks across increasingly complex modern attack surfaces. Its unified solutions bridge security gaps across diverse operational landscapes, protecting assets spanning traditional IT infrastructure, cloud environments, digital identities, web applications, and operational technology (OT) or critical infrastructure. Tenable's flagship platform, Tenable One, unifies data signals, exposure intelligence, and asset visibility to deliver actionable context and orchestrate rapid remediation efforts before vulnerabilities can be actively exploited. Tenable operates globally, serving over 44,000 customers worldwide, including approximately 65% of the Fortune 500 and half of the Global 2000 companies. While the United States remains its largest commercial market, the company maintains a robust international presence across Europe, Israel, and the Asia-Pacific region. Tenable utilizes a diversified, predominantly subscription-based go-to-market model, combining direct enterprise sales motions with a vast network of channel partners, distributors, and managed security service providers (MSSPs). This enables the company to efficiently serve large enterprises, heavily regulated financial and healthcare institutions, critical infrastructure operators, and smaller commercial midmarket accounts. Tenable transitioned into a publicly traded company in July 2018, launching its initial public offering on the NASDAQ stock exchange under the ticker symbol TENB. Financially, the corporation has experienced scaling growth, reporting a trailing 12-month revenue of $1.02 billion as of March 31, 2026. The company employs approximately 2,000 workers globally and maintains a highly regarded workplace culture. Following the passing of long-time CEO Amit Yoran in early 2025, the company's executive leadership structure transitioned to an interim co-CEO model managed jointly by Chief Financial Officer Stephen Vintz and Chief Operating Officer Mark Thurmond, alongside Board Chairman Art Coviello. To sustain its competitive edge and accelerate platform expansion, Tenable continues to invest heavily in technological innovation, including a dedicated venture capital division established in 2023 and strategic corporate acquisitions targeted at cloud security, active directory protections, and automated remediation workflows.
