Summary

Tenable has introduced a new OT asset discovery engine integrated into its Tenable One Exposure Management Platform. This tool enables security teams to identify and manage risks associated with cyber-physical systems, including operational technology (OT), Internet of Things (IoT), and shadow IT, without the need for additional hardware or software agents. The deployment is immediate and requires no extra IT overhead, allowing organizations to gain comprehensive visibility into their IT and OT environments. Early access customers reported uncovering between 100 and over 1,000 previously unknown OT and IoT assets, some with critical vulnerabilities. The convergence of IT and OT responsibilities is highlighted, as over half of Chief Information Security Officers (CISOs) now oversee OT security, with 45% of OT compromises originating from IT environments. This launch aims to address operational blind spots and streamline compliance with evolving cyber-physical regulatory requirements. Key Points: • Tenable's new OT discovery engine allows immediate visibility into cyber-physical assets. • Over half of CISOs are now responsible for OT security, reflecting a shift in cybersecurity responsibilities. • Early users identified significant numbers of previously unknown assets, many with critical vulnerabilities.
