The network interface device includes multiple systems and can be configured to perform multiple levels of security functions. In an example, the network interface device includes a first system and a second system. The first system includes a first interface configured to couple the first system with a host system of the electronic device, a second interface configured to couple the first system with an external electronic device, and first integrated circuits configured to monitor and filter traffic flowing between the external electronic device and the host system of the electronic device. The second system includes second integrated circuits. The network interface device also includes a communication channel between the first system and the second system. The second system is configured to send control information to and receive status information from the first system via the communication channel.
