About Tenable

Tenable was founded in 2002 by Ron Gula, Jack Huffard, and Renaud Deraison. As per the Company’s materials, Tenable is the leading provider of exposure management solutions. Exposure management is an increasingly critical category that extends foundational vulnerability management capabilities to advance risk assessment and prioritization across the entire attack surface – from IT infrastructure and cloud environments to critical infrastructure and artificial intelligence (AI). Tenable unifies security visibility, insight and action across this attack surface, equipping modern organizations to quickly identify and close the cybersecurity gaps that erode business value, reputation and trust.

The Company reported $262 Million in first quarter revenue for the period ended March 31, 2026. Combined with results from the preceding quarters, this recent performance boosts Tenable across the $1 Billion in annual revenue threshold as measured on a last twelve month basis to become the latest software Revenue Unicorn.
