An automotive network switch includes multiple ports, a switch core and one or more processors. The ports are configured to receive packets from electronic subsystems of a vehicle over a computer network deployed in the vehicle, and to transmit the packets to other electronic subsystems of the vehicle over the computer network. The switch core is configured to receive the packets from one or more of the ports, to forward the packets to at least one of the ports, and to transmit the packets over network links of the computer network. The processors are configured to obtain at least some of the packets processed by the switch, to analyze the obtained packets to identify an anomaly in one or more of the electronic subsystems of the vehicle, and to send a notification of the anomaly over the computer network to a central processor that is external to the switch.
