What is the primary benefit of using Nozomi Guardian for OT security?

Nozomi Guardian provides passive network monitoring, meaning it identifies assets and threats by analyzing traffic copies (from SPAN/TAP ports) without injecting traffic that could disrupt sensitive Industrial Control Systems (ICS).

What industrial protocols are supported?

Nozomi is protocol-aware and supports a wide range of industrial protocols (Modbus, Profinet, EtherNet/IP, etc.) to perform deep packet inspection and detect anomalies.

Does this skill support active vulnerability scanning?

No, this skill specifically focuses on passive monitoring and traffic analysis. For active scanning, dedicated OT-safe vulnerability tools or specific 'smart polling' features should be used.

Can I manage multiple sensors with this skill?

Yes, the skill covers workflows for centralized management through Nozomi Vantage (cloud) or the Central Management Console (CMC) for multi-sensor deployments.

Security & Testing

Deploys and manages Nozomi Networks Guardian sensors for passive OT/ICS network monitoring and real-time threat detection.

This skill empowers security professionals to implement comprehensive OT network visibility and security using the Nozomi Networks platform. It provides structured guidance and automation patterns for deploying Guardian sensors, extracting asset inventories, and analyzing industrial protocol traffic without disrupting sensitive operations. By leveraging behavioral anomaly detection and protocol-aware monitoring, users can build robust OT Security Operations Centers (SOCs) and maintain compliance with industrial standards like IEC 62443.
