Tenable

Tenable is a leading cybersecurity company that specializes in Exposure Management, a discipline focused on understanding and reducing cyber risk across an organization's entire attack surface. The firm's flagship offering, Tenable One, is an AI-powered platform designed to provide unified visibility, insights, and actionable intelligence across diverse environments, including IT infrastructure, cloud resources, containers, web applications, identity systems, and operational technology (OT)/Internet of Things (IoT) assets. Tenable's solutions help modern organizations identify and close cybersecurity gaps to protect business value, reputation, and trust.

Founded in September 2002 as Tenable Network Security, Inc., the company was established by Ron Gula, Jack Huffard, and Renaud Deraison. Deraison, at just 17, developed the widely recognized Nessus vulnerability scanner in 1998, which became a foundational component of Tenable's offerings. The founders' vision was to empower all organizations to comprehensively understand and effectively reduce their cybersecurity risk. Tenable became a public company in July 2018, trading on the Nasdaq under the ticker symbol TENB.

In January 2023, Tenable launched its venture capital division, Tenable Ventures, with plans to invest up to $25 million in innovative cybersecurity companies. While the firm itself has received significant funding rounds in its history from notable investors like Accel Partners and Insight Partners, specific portfolio companies of Tenable Ventures are not yet widely publicized given its recent inception. Tenable has also strategically acquired several companies, including FlawCheck, Indegy, Bit Discovery, and Vulcan Cyber, to enhance its product portfolio and capabilities.

The team at Tenable possesses deep expertise in the cybersecurity domain, stemming from its founders' backgrounds, which include experience at the National Security Agency and the creation of industry-standard tools like Nessus. This expertise is reflected in their continuous innovation in vulnerability assessment, exposure analytics, and the development of advanced platforms that address the evolving landscape of cyber threats. The company's focus on AI-powered solutions further highlights its commitment to leveraging cutting-edge technology to provide comprehensive security posture management.
