Security is no longer a siloed effort. Find out how Tenable integrates mature industrial security capabilities into an enterprise-ready approach for unified exposure management.
Key takeaways
- In our view, this year’s Gartner Magic Quadrant for CPS Protection Platforms validates a critical market transition away from a sole focus on niche, standalone OT tools. By integrating mature OT capabilities into our Tenable One exposure management platform, we are helping organizations move past siloed security to a proactive, unified view of risk across IT, cloud, identity, and cyber-physical systems. We find that our placement in the report demonstrates how Tenable OT Security delivers “ground truth” asset visibility and risk-based vulnerability management as mature technical strengths, powered by our industry-leading threat intelligence database and 65,000+ IDS rules for network intrusion and anomaly detection. We believe that eliminating silos between IT and OT is essential. Our placement reflects our ability to help customers communicate cyber exposure across their entire attack surface.
We are proud to announce that Gartner® has recognized Tenable as a Challenger in the 2026 Magic Quadrant for CPS Protection Platforms. Here at Tenable, our mission has always been to provide the shared clarity and context organizations need to effectively secure their most critical assets and connected IT/OT environment. The traditional boundaries between IT, cloud, and operational technology (OT) have effectively vanished. In today’s modern enterprise, a cyber-physical threat is rarely an isolated event”, it is an exposure problem that spans the entire attack surface. In our view, this recognition further validates our commitment to a unified approach. While many in the industry still view cyber-physical systems (CPS) as a siloed security challenge, Tenable is doubling down on helping our customers integrate these critical assets into a holistic exposure management strategy.
Technical maturity and coverage
Success in OT security is no longer measured solely by the number of sensors deployed or the size of your asset inventory alone. It is defined by how effectively an organization can translate OT threat intelligence and security data into actionable business context. Tenable OT Security, part of the Tenable One exposure management platform, addresses this by integrating mature OT security capabilities into a unified view, breaking down the traditional silos that hold teams back. In the 2026 report, we believe Gartner ranked us favorably due to the strength of Tenable’s core functionality and our unique position in the market with a broader security platform that spans IT, OT, and beyond. Our Tenable OT Security product is mature in terms of core capabilities, such as asset discovery and vulnerability management, which are core focus areas for Tenable’s research and product development teams. Additionally, Tenable OT Security integrates seamlessly with the Tenable One exposure management platform and Tenable Security Center for advanced reporting and analytics. In our view, we were recognized by Gartner for our commitment to serving a diverse range of industries. This is evidenced by our deep coverage and technical expertise in Safe Active Query, leveraging native CPS/OT protocols, as well as detection for BACnet/IP and Intelligent Platform Management Interface (IPMI) to identify unauthorized changes to mission-critical OT assets such as HVAC and power systems. IPMI is an often vulnerable, hardware-based specification for out-of-band (OOB) server management via a Baseboard Management Controller (BMC), allowing remote power control, console access, and monitoring, even when the OS is down. Due to potential exposure, it requires strict, isolated network security to prevent unauthorized access. Additionally, we find that our broad geographic coverage and extensive channel-partner network in North America, Europe, and Asia/Pacific contributed significantly to our recognition, demonstrating our long-standing commitment to global customer support and scalability. Our maturity in this space is the engine behind our OT security offerings. We help our customers translate technical OT security data into a true understanding of their cyber exposure.
Mature asset discovery and vulnerability management
Comprehensive visibility is the prerequisite for any security program. Tenable OT Security uses a proprietary hybrid discovery engine that combines passive network monitoring with safe, active querying to ensure “ground truth” situational awareness. Unlike passive-only tools that wait for traffic, our solution safely queries controllers (PLCs, RTUs, and IEDs) in their native protocols to identify critical details”, including vendor, firmware, backplane details, and more”, without risk of operational disruption. By applying our Vulnerability Priority Rating (VPR) to your OT/IoT data, Tenable OT Security identifies the small fraction of vulnerabilities that pose the greatest actual risk, allowing teams to prioritize remediation during limited maintenance windows. When this data is accessed in Tenable One, OT assets are evaluated on the same scale as IT and cloud assets, giving security leaders access to a single, comparable set of metrics to communicate cyber exposure.
Ease of use and centralized administration
One of the greatest challenges in OT security is the friction between “IT security” mandates and “OT availability” goals. Tenable OT Security bridges this gap by providing a unified view that appeals to both the control room and the C-suite. Tenable OT Security offers centralized administration with granular role-based access control (RBAC) capabilities. It combines configuration-level OT data from our industrial core platform sensors with IT data from Tenable Nessus, and agents for unified oversight. Beyond external threats, operational resilience depends on maintaining the integrity of device configurations. Tenable OT Security provides granular configuration control to track every change at the logic level. We detect unauthorized modifications to PLC code, firmware downloads, or setpoint changes, which enables rapid recovery from cyber incidents or human errors while significantly reducing potential downtime. And by combining OT-specific insights with IT vulnerabilities and identity data for AI-powered attack path analysis, Tenable One helps security teams pinpoint exactly how an attacker could pivot from a compromised IT identity to disrupt critical OT assets.
Strategic roadmap and product innovation
Our customer-first roadmap reflects a consistent focus on enterprise-wide scalability and ease of use. Throughout 2025, we prioritized enhancing our CPS exposure management capabilities by introducing agent-based deployment and centralized administration in Tenable OT Security Enterprise Manager. In our view, these capabilities”, including bulk and rule-based software updates and OS upgrades from a single console”, are essential for organizations managing security across distributed global sites. Our vision for 2026 includes advancing global subnet management to improve asset tracking and the detection of unauthorized traffic. We also plan to integrate deeper CPS security capabilities directly inside our core vulnerability management solutions, Tenable Vulnerability Management and Tenable Security Center, lowering the barrier to entry for security teams inheriting responsibility for securing CPS/OT environments regardless of which Tenable solutions they use.
Customer experience
We are committed to a customer-centric approach that prioritizes ease of use and operational safety. From user-focused demos and self-service onboarding, we are committed to helping security teams reduce the friction of adoption. Additionally, we believe our phased Proof of Value (PoV) methodology is designed specifically for the unique constraints and complexity associated with today’s OT/IT environments. By intentionally structuring our deployments to respect operational freeze days and scheduled safety windows, we are able to partner effectively with engineering teams to ensure that security never comes at the expense of uptime or availability.
Connecting the dots
To us, being named a Challenger in this year’s report is a testament to our commitment to proactive security. We believe that by treating CPS assets as a core part of the broader attack surface, organizations can move from reactive defenses to true exposure management. This recognition follows our placement as a Leader in the inaugural 2025 Gartner® Magic Quadrant for Exposure Assessment Platforms, which we find reinforces our long-standing perspective that the market is rapidly shifting toward exposure management. Tenable remains focused on helping you bridge the IT/OT divide, ensuring that security never comes at the expense of availability and operational integrity.
