What is Tenable?

Tenable is a cybersecurity company focused on exposure management, helping organizations understand and reduce their cyber risk by finding and prioritizing the weaknesses attackers could exploit across IT, cloud, operational technology (OT), identity systems, and increasingly the AI attack surface. It is best known as the maker of Nessus, one of the most widely used vulnerability scanners, and of Tenable One, its exposure-management platform that unifies visibility and prioritization across an organization's environment. Tenable has been expanding into cloud and AI security, including acquisitions such as Apex Security. It was founded in 2002 in Columbia, Maryland, with co-founders including Renaud Deraison, the creator of Nessus, and it went public on the Nasdaq (ticker TENB) in 2018. The company employs on the order of 2,000 or more people worldwide. On leadership: Amit Yoran, who led Tenable as chairman and CEO from 2016 through its growth and IPO, passed away in January 2025. Following that, the board appointed Steve Vintz, previously the company's CFO, and Mark Thurmond, previously its COO, as permanent co-CEOs in April 2025; Vintz oversees product, security, corporate development, and G&A, while Thurmond oversees go-to-market.

Mission & values

Help organizations understand and reduce their cyber risk by managing exposure across their entire attack surface.

Qualifications

Tenable hires across the functions of a public cybersecurity company. On the technical side: software engineering (backend, frontend, full-stack, cloud, data), security research and vulnerability research (the people who find and analyze vulnerabilities), detection and cloud-security engineering, data science and machine learning, site reliability and security, and product management and design. Because it sells to enterprises and governments, it hires heavily in technical go-to-market too: sales engineering and solutions architecture, professional services, technical support, and customer success, alongside sales and channel, marketing, finance, legal, and people. Application flow lives at tenable.com/careers. Tenable is headquartered in Columbia, Maryland, and hires across the US and internationally; some roles are remote or hybrid and others are tied to an office, and work authorization requirements depend on the country, and some government-facing work may carry clearance or citizenship requirements. Deep security expertise (vulnerability management, cloud security, or exposure management) is a strong signal for technical and field roles. Check each posting.
