Nozomi Networks secures operational technology (OT) and IoT environments for critical infrastructure operators such as electric utilities, water and wastewater, oil and gas, manufacturing, mining, rail, airports and healthcare. Its platform discovers every connected asset, watches network, wireless and endpoint activity, and flags the threats and process anomalies that matter so that industrial teams can respond before operations are disrupted.
It is built for industrial security and engineering teams who need to see every asset and catch threats without disturbing the processes those assets run.

What Nozomi Networks Does
Industrial networks mix decades-old controllers, wireless devices and modern IT, and a single unseen asset can become the way in. Nozomi Networks focuses on keeping that infrastructure cyber resilient through continuous monitoring combined with AI-assisted analysis, giving visibility and management from the endpoint to the air. Detection is tuned to surface real threats without leaving analysts to sort and correlate alerts by hand.
The platform also supports the compliance frameworks that govern these sectors, including ISA/IEC 62443, NERC CIP and NERC CIP-015, NIS2, SEC cybersecurity rules, TSA Security Directives and DoW zero trust for OT. Nozomi Networks reports more than 115 million devices monitored.
Products
Guardian, Guardian Air And Arc Sensors
Guardian is the core sensor for wired networks. It builds the asset inventory for OT and IoT environments and gives operators visibility of what is talking to what on the plant floor. Guardian Air extends that visibility to the wireless spectrum, where rogue or unmanaged wireless devices are otherwise hard to see. Arc brings visibility and protection to endpoints in the operational environment, and Arc Embedded runs as a security sensor inside ICS endpoints themselves.
Vantage And Central Management Console
Vantage Cloud is the cloud management option, and the Central Management Console serves organisations that need management on-premises. Both bring the sensor data together for monitoring and response. Alongside them, Compass OTSM modernises the everyday work of OT asset and service management for engineering and operations teams.
Vantage IQ
Vantage IQ is a private OT and IoT cybersecurity assistant that extends the reach of security teams. It uses an LLM grounded in OT-native intelligence, built on real-time telemetry and more than 13 years of OT and ICS machine learning to support analysis. Custom Personas let it work as a SOC analyst, an OT engineer or a CISO would.
Enhancements
| Threat Intelligence | OT and IoT specific intelligence curated by Nozomi Networks Labs, with a TI Expansion Pack powered by Mandiant. |
|---|---|
| Asset Intelligence and Smart Polling | Richer asset detail, with Smart Polling adding active collection where passive monitoring is not enough. |
How It Works
Monitoring is non-intrusive, continuously discovering and mapping connected assets across wired and wireless networks.
| Component | What it does |
|---|---|
| Sensors | Guardian, Guardian Air, Arc and Arc Embedded combine passive network sensing with active collection techniques to suit each site. |
| Management | Vantage Cloud or the on-premises console sits above the sensors, and the management framework can be nested and distributed across thousands of locations. |
| Deployment | Certified partners can deploy the platform on-premises, as part of a hybrid network or with cloud resources, or run it as a managed service. |
