Your Role

Tenable OT Security was established through the acquisition of a pioneering Israeli cybersecurity startup, marking a major milestone in Tenable’s mission to provide proactive security for the world's most sensitive environments. Our solution offers critical visibility and risk management for Industrial Control Systems (ICS/SCADA), protecting essential infrastructures such as power plants, manufacturing floors, and smart buildings. While traditionally an on-premises solution designed to ensure operational continuity and prevent costly downtime, we are now evolving our technology to deliver market-leading risk visibility through advanced architectures and AI-driven capabilities. By combining deep on-premises expertise with proactive AI insights, we empower organizations to identify threats and network anomalies before any damage occurs
