Key Takeaways
- Tenable has rolled out an VM‑Native OT Discovery engine that is built directly into its core Tenable One Exposure Management Platform, requiring no extra hardware, agents, or add‑ons.
- The new capability gives security teams instant, non‑disruptive visibility into cyber‑physical assets (OT, IoT, shadow IT) and their attributes, helping close a rapidly expanding attack surface that now stretches from factory floors to AI data‑centers and office devices.
- Early‑access customers across multiple sectors discovered 100‑1,000+ previously unknown OT/IoT devices, many bearing critical vulnerabilities, underscoring the hidden risk that exists where IT and OT environments converge.
- By unifying OT data with existing IT, cloud, identity, and AI exposure information, the engine supports faster compliance, reduces operational blind spots, and breaks down traditional security silos.
- Tenable also offers a full‑featured Tenable OT Security solution for more complex use cases, and the discovery engine works alongside the recently announced Tenable Hexa AI agentic AI engine to automate workflows and turn exposure intelligence into coordinated risk‑reduction actions.
- The OT Discovery capability is immediately available to all Tenable One, Tenable Vulnerability Management, and Tenable Security Center customers at no additional deployment overhead.
Introduction to Tenable’s New OT Asset Discovery
Tenable announced a VM‑Native OT Discovery engine that allows security teams to rapidly bring cyber‑physical systems—including OT, IoT, and shadow IT—into a unified view of cyber exposure. The capability is designed for instant deployment with zero additional IT overhead, providing a low‑friction entry point for organizations seeking comprehensive IT/OT visibility and faster AI‑driven exposure management.
Industry Context and Gartner’s Warning
According to Gartner, “Cyber and cyber‑physical attacks are set to double over the next three years. Cohesive exposure management capability and visibility, across cyber and cyber‑physical dimensions, is fast becoming an operational imperative.” This forecast highlights the growing urgency for security leaders to protect not only traditional IT assets but also the expanding universe of cyber‑physical devices that underpin critical infrastructure and everyday business operations.
The Visibility Challenge in OT Environments
Security teams are increasingly tasked with safeguarding cyber‑physical systems, yet gaining visibility traditionally requires time‑consuming deployments of specialized hardware, new agents, and bolt‑on software. These barriers have left OT as a dangerous blind spot where IT networks meet physical processes, and fears of operational disruption have slowed cybersecurity progress. Consequently, 45 % of modern OT compromises now originate in IT environments, illustrating the risk introduced by the convergence of IT and OT.
Early‑Access Findings Reveal Hidden Assets
Tenable’s early‑access customers—spanning hospitality, financial services, education, food and beverage, and government—deployed the new OT discovery engine and immediately uncovered a large number of previously unknown OT and IoT assets. Most organizations identified between 100 and 1,000+ unique devices, many of which carried critical vulnerabilities. These findings underscore the scale of the hidden attack surface that exists beyond traditional industrial settings.
Immediate Practical Benefits for Compliance and Visibility
The integrated OT discovery engine delivers instant, practical gains across three key areas: compliance, visibility, and operational alignment. By eliminating the need to procure and install additional sensors, hardware, or point solutions, teams can accelerate OT security compliance and meet evolving cyber‑physical regulatory and audit requirements with greater confidence. At the same time, the engine provides immediate visibility into hidden assets and detailed device attributes—such as vendor, model, firmware, backplane details, and runtime state—without disrupting ongoing operations.
Breaking Down Security Silos with Unified Data
Beyond visibility, the technology breaks down long‑standing security silos by unifying cyber‑physical asset and exposure data within the Tenable One platform. This consolidation gives security teams a comprehensive view of total cyber exposure across AI, IT, cloud, identity, and OT environments. The unified data model enables correlated risk scoring, streamlined reporting, and more effective prioritization of remediation efforts across the entire attack surface.
Executive Perspective on the Launch
Eric Doerr, Chief Product Officer at Tenable, emphasized the strategic value of the new capability: “Cyber‑physical risk can’t remain a blind spot in exposure management. We’re giving organizations an immediate, low‑friction way to bring OT into scope, so they can gain visibility, meet compliance requirements and start reducing risk from day one, without adding new infrastructure.” For customers with more complex OT requirements, Tenable continues to offer Tenable OT Security, a comprehensive solution that delivers continuous monitoring, threat detection, and control for proactive risk reduction across today’s converging OT/IT landscape.
Availability and Integration with Tenable One
The VM‑Native OT Discovery engine is immediately available to all Tenable One, Tenable Vulnerability Management, and Tenable Security Center customers. Because it is native to the Tenable One Exposure Management Platform, it benefits from seamless data interoperability with other Tenable solutions. Organizations can mix and match tools—such as vulnerability management, cloud security, identity exposure, and the OT discovery engine—to suit the unique needs of their environment without incurring additional deployment complexity.
Complementary Innovations: Tenable OT Security and Tenable Hexa AI
In addition to the discovery engine, Tenable offers Tenable OT Security, a unified OT/IT security solution that provides continuous monitoring and threat detection for cyber‑physical systems as part of the Tenable One platform. This option enables deeper security and control for organizations with sophisticated OT environments. Furthermore, Tenable recently introduced Tenable Hexa AI, the agentic AI engine of the Tenable One Exposure Management Platform. Hexa AI automates security workflows, transforms exposure intelligence into coordinated action, and helps security teams keep pace with AI‑powered cyberattacks, rapid vulnerability discovery, and the proliferation of AI‑driven tools that continually expand the attack surface.
Conclusion: A Low‑Friction Path to Holistic Exposure Management
Tenable’s VM‑Native OT Discovery engine addresses a critical gap in modern cybersecurity strategies by providing instant, non‑intrusive visibility into the rapidly growing cyber‑physical attack surface. By removing hardware and agent requirements, delivering immediate compliance advantages, unifying data across IT and OT domains, and integrating with advanced AI capabilities, the engine empowers security teams to reduce risk from day one. As cyber‑physical threats continue to rise, this low‑friction, platform‑native approach offers a practical foundation for comprehensive exposure management and resilient security operations.
