Summary

Tenable has introduced a new OT asset discovery engine integrated into its exposure management products, aimed at providing unified visibility of cyber-physical systems. This tool allows security teams to identify operational technology (OT), internet-connected devices, and shadow IT assets without needing additional hardware or software. The launch reflects a growing trend where chief information security officers (CISOs) are increasingly responsible for OT security, with over half now overseeing these systems. Early-access deployments revealed that organizations uncovered between 100 and over 1,000 previously unknown OT and IoT assets, some of which had critical vulnerabilities. The integration is designed to streamline compliance with evolving regulatory demands and improve visibility into environments that have historically been blind spots. This development is crucial as the attack surface associated with cyber-physical systems continues to expand. Key Points: • Tenable's new OT discovery engine integrates with existing exposure management tools. • Organizations can identify previously unknown OT and IoT assets without additional infrastructure. • Over half of CISOs are now responsible for OT security, highlighting the convergence of IT and OT.
