With Transparent Bridge mode, Deep Discovery Web Inspector (the appliance) acts as a layer 2 bridge between network devices (core switch, router, or firewall) and is transparent on the network.

Deep Discovery Web Inspector performs security scans on HTTP/HTTPS traffic that passes through the ingress and egress ports and takes action if there is a traffic match according to configured policies. The appliance can bypass scanning and let the traffic pass straight through the appliance, block the traffic without scanning, or scan the traffic and then either block or monitor the traffic, depending on actions configured in policies.

Transparent Bridge mode is suitable when you want to use Deep Discovery Web Inspector as an inline device and there is only one network path that you want to monitor. If you set up the appliance in Transparent Bridge mode, you do not need to reconfigure your network as you need only place the appliance in the network path that you want to secure.

For environments where higher bandwidth is required for data ingress and data egress, you can implement a Transparent Bridge deployment with trunks using LACP link aggregation.
