In this sample architecture, three sensors connect to four routers in different logical zones across the organization. The sensors are located behind a firewall and integrate with local, on-premises IT infrastructure, such as local backup servers, remote access connections through SASE, and forwarding alerts to an on-premises security event and information management (SIEM) system.

Defender for IoT now provides new guidance for connecting to and monitoring hybrid and air-gapped networks. The new architecture guidance is designed to add efficiency, security, and reliability to your SOC operations, with fewer components to maintain and troubleshoot. The sensor technology used in the new architecture allows for on-premises processing that keeps data within your own network, reducing the need for cloud resources and improving performance.
