Nozomi Networks

Nozomi Guardian is an industrial cybersecurity platform that provides real-time network visibility, threat detection, and vulnerability assessment for operational technology (OT) and IoT environments. It uses passive network monitoring and machine learning to discover assets, identify vulnerabilities, and detect cybersecurity threats and operational anomalies. 

Guardian supports hundreds of industrial protocols and automatically builds a detailed network map with asset inventories, communication patterns, and vulnerability assessments. It generates security alerts for protocol anomalies, known threats, unauthorized changes, and behavioral deviations, providing OT security teams with actionable intelligence to protect critical infrastructure environments.
