Nozomi Guardian Sensor – Passive OT/IoT Network Monitoring

Foundational Data Collection and Monitoring for OT and IoT Cybersecurity

Nozomi Guardian sensors passively observe and analyze local network traffic for comprehensive OT/IoT asset visibility, continuously monitoring communications to identify devices, protocols and vulnerability risks.

Key capabilities

• Transparent Deployment —— Sits on SPAN ports or taps, monitoring traffic without disrupting critical processes
• Automatic Asset Discovery —— Detects communicating devices and collects type, firmware, serials for risk assessment
• Topology & Baselining —— Builds network topology graphs and baselines of normal behavior patterns
• Anomaly & Threat Detection —— Flags deviations, unusual process values and threats, routing them into response workflows
