  - Guardian
    Guardian is the main Nozomi Networks sensor.
  - Guardian Air
    Guardian Air is a wireless security sensor for operational technology (OT) and Internet of Things (IoT) environments. It monitors in real-time activities from prominent wireless frequencies, to provide immediate visibility to connected assets and attack surfaces. Guardian Air seamlessly integrates with Vantage for unified visibility of wired, wireless and endpoint assets across your OT and IoT environments.
  - Remote Collector
    Remote Collectors let you deploy sensors in multiple isolated locations. Remote Collectors must be connected to a Guardian and act as a remote interfaces, that broaden its capture capability.

Network sensors

Discover how Guardian, Guardian Air, and Remote Collector sensors provide comprehensive monitoring, threat detection, and asset visibility for secure and distributed environments.

Nozomi Networks offers three specialized network sensors:

Guardian
Guardian Air
Remote Collector

Guardian, the flagship sensor, provides these capabilities across the entire across the entire operational technology (OT) network:

Comprehensive monitoring capabilities
Threat detection
Asset visibility

It analyzes network traffic in real-time, identifying potential threats to ensure the integrity of critical systems.

Guardian Air is a wireless version of Guardian, and is ideal for monitoring environments where wired connections are impractical, such as remote or hard-to-reach areas. It offers the same robust security features as Guardian, but with the flexibility of wireless deployment.

Remote Collector is designed for edge environments, collecting and forwarding data from remote sites, or isolated network segments, to the central management system. This allows for continuous monitoring and threat detection across widely distributed or segmented networks, ensuring that even the most remote assets are protected. Together, these sensors provide a comprehensive solution for securing complex and distributed OT environments.
