OT and IoT security and visibility for faster response to anomalies and threats

Nozomi Networks Guardian unlocks visibility in your converged OT and IoT networks for accelerated security and digital transformation.

Guardian delivers network visualization, asset inventory, vulnerability assessment, and threat detection in a single application.

    • Its unified approach to visibility and monitoring enables you to detect and respond to cyber threats, risks, and anomalies across your network.
    • It integrates quickly with your existing IT security infrastructure and processes for streamlined workflows and faster response.


Users who will benefit:

  • Executive Management will benefit from greater efficiency of existing resources by accelerating detection and response, reducing downtime and lowering costs from unplanned disruptions.
  • Network or Security Operations teams will benefit from comprehensive visibility of diverse OT/IoT networks and assets, regardless of vendor. Guardian delivers fast, accurate security and operational anomaly assessment without affecting mission-critical OT networks.


Guardian simplifies and accelerates detection and response to operational anomalies and cyber threats:

Centralized Security and Visibility

      • Single console access delivers unified summary of all network activity with drill-down of detailed information.

Immediate Visibility of Your Network

      • Guardian presents risk information including security and reliability alerts, including missing patches and vulnerabilities.
      • Summary-level and detailed information on endpoints and connections, which you can also filter by subnets, type, role, zone and topologies.

Unmatched OT and IoT threat detection accuracy 

      • Guardian combines behavior-based anomaly detection with signature-based threat detection for comprehensive risk monitoring.
