Tenable Holdings, Inc. is a cybersecurity company best known for its focus on vulnerability management and continuous network monitoring. Founded in 2002 by Ron Gula, Jack Huffard and Renaud Deraison, the company pioneered the concept of continuous visibility into enterprise attack surfaces. Headquartered in Columbia, Maryland, Tenable has grown from its early roots as the developer of the Nessus vulnerability scanner into a broad-based security platform provider serving organizations across diverse industries.
The company’s flagship products include Tenable.io and Tenable.sc, which offer cloud-based and on-premise solutions, respectively, for identifying, investigating and prioritizing vulnerabilities and misconfigurations. Tenable.io provides scalable vulnerability management in modern IT environments, covering assets in cloud, container and traditional network infrastructures. Tenable.sc delivers advanced analytics and insights through a centralized console, enabling security teams to correlate vulnerability data with threat intelligence and compliance requirements. Additionally, Tenable’s Nessus Pro remains widely used for detailed vulnerability assessments, while complementary offerings such as Tenable Lumin translate raw data into actionable risk metrics and benchmarks.
Tenable serves a global customer base spanning North America, Europe, the Middle East, Asia-Pacific and Latin America. Its solutions cater to organizations of all sizes—including enterprises, government agencies and small-to-medium businesses—addressing the need for continuous cyber exposure management in dynamic IT landscapes. Over the years, the company has expanded its footprint through strategic partnerships and channel relationships, integrating with leading cloud platforms, endpoint solutions and service providers to deliver end-to-end security visibility.
Under the leadership of CEO Amit Yoran, Tenable has emphasized innovation and research-driven product development, leveraging threat intelligence from its 1.5 million-plus sensors and community contributions to Nessus. The executive team combines expertise in cybersecurity, software engineering and enterprise sales, guiding the company through its 2018 IPO and subsequent growth phases. As organizations increasingly adopt hybrid and multi-cloud environments, Tenable continues to evolve its platform, invest in machine learning capabilities and extend its product suite to help clients measure and reduce cyber risk effectively.
