NOZOMI GUARDIAN

Passive Network Security Monitoring for OT and IoT Asset Visibility

Foundational Data Collection and Monitoring for OT and IoT Cybersecurity

The Nozomi Guardian security sensor passively observes and analyzes local network traffic to provide comprehensive OT and IoT asset visibility. It continuously monitors network activity to discover newly connected assets, identify critical vulnerabilities and detect cybersecurity threats and operational issues.

Take a Deeper Dive into Top Use Cases

Passive, On-Prem Security Sensors for the Strictest Environments

Nozomi Guardian sensors work with other components of the Nozomi Networks platform to cover your entire environment. They can also be deployed independently or with only the Nozomi Central Management Console to accommodate restrictions.

Fully On-Prem & Air-Gapped Environments

Ideal for entities subject to data residency and cloud connectivity or reliability restrictions

Passive-Only Monitoring

Ideal for high-risk industrial environments that prohibit active querying (NERC CIP, nuclear, defense)

A Key Component of a Scalable, Multi-Tier Architecture

Nozomi Guardian sensors can be deployed as hardware appliances, virtual machines, embedded devices or containers and easily scale across any network size or complexity. They receive and process data from other Nozomi security sensors and collectors and send it to either an on-prem Nozomi Central Management Console or the Nozomi Vantage cloud management platform.

Platform Components

Vantage/Central Management Console centralize OT and IoT visibility and security on-premises and in the cloud
Guardian sensors process data and send it to Vantage
Guardian Air sensors extend the detection power of the Nozomi platform to the wireless spectrum
Remote Collectors send data streams to Guardian sensors
Arc endpoint sensors send in-depth asset and network information to Guardian sensors or directly to Vantage
