What is Tenable?

Tenable is the global leader in exposure management, providing vulnerability assessment for IT, OT, cloud, and web applications through products including Nessus, Tenable.io, and Tenable.sc. With coverage of 75,000+ CVEs and used by over 44,000 organisations, it is the most widely deployed vulnerability management platform in the enterprise security market.

Founded in 2002, Tenable has grown into one of the most recognised names in the Security space, trusted by thousands of businesses ranging from early-stage startups to Fortune 500 companies. The platform is designed to help security engineers and IT administrators and DevOps and platform engineering teams manage team passwords and credentials in an encrypted vault — without the steep learning curve or excessive cost that comes with many legacy enterprise tools.

At its core, Tenable solves a fundamental challenge: how do you scan codebases for vulnerabilities before they reach production as your team grows, data volumes increase, and workflows become more complex? The answer is a purpose-built security platform that combines cybersecurity platform, identity and access management, and password manager for teams in a single, cohesive interface. Rather than stitching together spreadsheets and disconnected point solutions, Tenable gives your team a single source of truth.

In 2026, Tenable remains a top choice for teams evaluating security software — particularly for use cases involving SSO software, multi-factor authentication tool, vulnerability scanning software. It consistently ranks alongside the best tools in the Security category for ease of use, feature depth, and customer support. If you are comparing security platforms, Tenable deserves a close look.

Overall, the pros significantly outweigh the cons for the majority of use cases.
