Nozomi Networks FAQ

How does the Nozomi Networks platform discover assets that don't communicate on the network?

The platform uses active querying via Smart Polling to non-invasively gather detailed information from embedded and non-communicating devices, complementing passive discovery techniques.

What types of wireless protocols does the Guardian Air sensor support?

The Guardian Air wireless sensor detects not only Wi-Fi and Bluetooth but also Zigbee, LoRaWAN, Drone RF, and other wireless protocols commonly used in OT/IoT environments.

Can the platform ingest asset data from third-party IT security tools?

Yes, third-party connectors ingest asset data from solutions like Microsoft Active Directory, Microsoft Defender, Cisco routers and switches, CrowdStrike, ServiceNow, and other leading IT security tools.

What is the difference between the network sensor and the remote collector?

Network sensors perform full passive data collection, analysis, and visualization, while remote collectors are low-resource devices designed for hard-to-reach and unmanned locations where a full sensor is not cost-efficient or practical.

How does the platform handle protocol support for obscure or custom industrial protocols?

Nozomi Networks provides a protocol software development kit (SDK) that allows quick creation of new protocol support on demand, in addition to covering hundreds of standard OT, IoT, and IT protocols.

Does the endpoint sensor require installation on Windows, Linux, and MacOS devices?

Yes, the endpoint sensors are lightweight, non-disruptive agents that support Windows, Linux, and MacOS endpoints and understand OT/IoT protocols, providing visibility down to Purdue Level 0.

What is the purpose of the learning mode during initial deployment?

Upon deployment, the platform operates in learning mode, monitoring device communications down to process-level variables to establish a baseline of normal behavior before switching to protection mode for anomaly detection.
