Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced that it has been named a Challenger in the 2026 Gartner® Magic Quadrant™ for CPS Protection Platforms. 

According to Gartner, “Cyber-physical systems protection platforms that discover assets and how they connect in product or mission-critical environments (such as OT, ICS, IoT and robotics) have become key CPS tools.” Modern cyber-physical systems (CPS) are deeply interconnected, enabling threats to quickly spread across domains if not properly locked down. Visibility and context-enriched exposure data are mission-critical to preemptive cybersecurity. 

The AI-powered Tenable One Exposure Management Platform (Tenable One) delivers a proactive, unified view of risk across IT, cloud, identity and cyber-physical systems. Tenable protects core operations, uncovers blind spots that put organizations at risk, prioritizes action based on business impact and helps security teams stop threats faster. By connecting the dots across domains, Tenable One OT Security offers the most complete view of risk necessary to secure the critical infrastructure underpinning building management systems, manufacturing plants, energy grids, water systems and beyond. 

“Tenable has a strong history in delivering proactive security protection for OT environments. A cyber-physical threat is rarely an isolated event—it is an exposure problem that spans the entire attack surface,” said Mark Thurmond, Co-Chief Executive Officer, Tenable. “By integrating OT data into our exposure management platform, we’re eliminating the silos that leave organizations exposed and equipping customers with the comprehensive exposure data and context needed to secure priority risk.”

Gartner also recently named Tenable a Leader in the first-ever 2025 Gartner® Magic Quadrant™ for Exposure Assessment Platforms¹ and recognized Tenable as the current Company to Beat for AI-Powered Exposure Assessment in the Gartner® report for AI Vendor Race.²
