Guardian

Industrial Strength OT and IoT Security and Visibility

Nozomi Networks Guardian™ unlocks visibility across OT, IoT, and IT for accelerated security and digital transformation.

Its physical or virtual appliances monitor network communications and device behavior, delivering instant awareness of your OT/IoT network and its activity patterns. You see the highest priority vulnerabilities as well as threats and anomalous behavior, enabling you to respond faster, ensuring high reliability and security.

Guardian reduces OT risks for the largest critical infrastructure, energy, manufacturing, mining, transportation, building automation and other OT sites around the world.
