About Tenable Holdings, Inc.

Tenable Holdings, Inc. (NASDAQ: TENB) is a U.S.-based cybersecurity software company focused on vulnerability management and, increasingly, on exposure management: identifying, prioritizing, and reducing security weaknesses across the full attack surface. Founded in 2002 and headquartered in Columbia, Maryland, United States, Tenable is best viewed by investors as an enterprise software vendor with a recurring-revenue profile and a mission centered on security visibility, analytics, and risk remediation. ([tenable.com](https://www.tenable.com/about-tenable/about-us?utm_source=openai)) The company originally built its reputation around Nessus, one of the most widely adopted vulnerability scanning tools in the market. Over time, it expanded beyond point products into a broader platform strategy. Today, its flagship offering is Tenable One, an exposure management platform designed to unify visibility, insight, and action across IT infrastructure, cloud environments, OT/IoT assets, and, more recently, AI-related attack surfaces. This strategic evolution matters because it moves Tenable from pure vulnerability detection toward a more executive-level risk management proposition, which can deepen platform usage and increase wallet share over time. ([tenable.com](https://www.tenable.com/about-tenable/about-us?utm_source=openai)) In competitive terms, Tenable operates in a crowded cybersecurity landscape alongside vendors spanning vulnerability management, attack surface management, cloud security posture management, and adjacent exposure-reduction tools. Its differentiation is built on broad CVE coverage, cross-domain visibility, and decision-ready prioritization for security teams. The company says it serves more than 40,000 customers worldwide, including a significant share of large global enterprises, which indicates meaningful scale and strong enterprise credibility. ([tenable.com](https://www.tenable.com/about-tenable/about-us?utm_source=openai)) Geographically, Tenable has a global footprint and operates across dozens of countries, which aligns with its enterprise and public-sector customer base. Its listing on the NASDAQ, rather than the NYSE, reinforces its identity as a technology growth stock rather than a traditional industrial or financial issuer. ([tenable.com](https://www.tenable.com/about-tenable/about-us?utm_source=openai)) Recent developments underscore the company’s current strategy. In early 2026, Tenable reported full-year 2025 revenue of roughly $999 million, alongside stronger cash generation and an increased share repurchase authorization. Product-wise, the company has recently introduced new OT discovery capabilities, new AI-focused exposure features, and more flexible pricing and packaging, signaling a push to accelerate adoption of Tenable One and to remain relevant as the attack surface broadens across cloud, AI, and cyber-physical systems.
