Nozomi Networks + Elisity: OT/IoT Visibility and Microsegmentation Integration

The Nozomi Networks and Elisity integration passes Nozomi’s OT and IoT device intelligence into Elisity’s IdentityGraph™ over an API, and Elisity turns that context into enforced microsegmentation policy. Nozomi Guardian and Vantage discover, classify, and profile every OT and IoT device using passive network monitoring and deep packet inspection. You connect the two products by entering Nozomi API credentials in the Elisity Cloud Control Center, which takes minutes. Device type, manufacturer, model, operating system, and firmware version then flow into IdentityGraph™ continuously. Elisity enforces the resulting least-privilege policies through your existing network infrastructure, so you get Zero Trust protection without adding new hardware or installing endpoint agents.

No. The Nozomi Networks and Elisity integration is fully agentless on both sides. Nozomi uses passive network monitoring to discover and classify devices without touching endpoints, and Elisity enforces segmentation policies through the network devices you already own. That architecture matters in OT environments because most industrial devices cannot support software agents: they run legacy operating systems, carry vendor restrictions, hold safety certifications that prohibit modifications, or perform operations too sensitive for additional software. With Nozomi and Elisity, you get full visibility and microsegmentation enforcement without ever installing software on a production endpoint.

The Nozomi Networks and Elisity integration covers the full range of industrial and IoT assets Nozomi profiles: programmable logic controllers (PLCs), remote terminal units (RTUs), distributed control systems (DCS), SCADA systems, building management systems, and thousands of IoT device types. Nozomi supports over 100 OT and IoT protocols, including Modbus, BACnet, DNP3, EtherNet/IP, PROFINET, and OPC UA. All of that device context, including protocol-specific attributes, flows into Elisity’s IdentityGraph™, so your microsegmentation policies reflect what each device actually is and how it communicates, not just its IP address or VLAN assignment.

Nozomi Networks and Elisity map directly to IEC 62443’s zone and conduit segmentation requirements. Nozomi classifies devices into functional groups based on their role, protocol behavior, and risk profile. Elisity turns those classifications into policy groups with least-privilege access controls, so each zone permits only the conduits it is supposed to. Instead of defining zones in spreadsheets and hoping your VLANs match, you get policy that stays current as devices join the network or move between areas, with a per-policy audit trail in the Elisity Cloud Control Center. The same identity-based approach supports NIST CSF, NERC CIP, and other industrial compliance frameworks.

The API connection between Nozomi Networks and Elisity takes minutes to set up: you enter Nozomi API credentials in the Elisity Cloud Control Center, and device data starts enriching Elisity’s IdentityGraph™ immediately. From there, most organizations reach enforced microsegmentation in weeks rather than the months or years traditional network segmentation projects require. Elisity uses Nozomi’s device classifications to build policy groups automatically, which removes the manual device inventory, network redesign, and VLAN reconfiguration that slow legacy approaches down. Enforcement runs on the network infrastructure you already own, so there is no new hardware to procure, rack, or cable.
