Sentinel-CAN is an SDK integrated into an ECU. It may be an existing ECU such as a gateway, a TCU, or a dedicated ECU attached to the CAN-Bus in-vehicle network.

Incoming CAN messages are routed to SENTINEL-CAN

Messages are inspected and any anomaly is reported

When configured as an IPS, messages hazardous to safety or functionality are discarded
