I’m working with a midsize business looking to ditch their Surfcontrol/ISA setup. They want an inline filtering appliance and have already looked at Barracuda and 8e6 Technologies. The problem is they want most of the users filtered transparently (bridge mode proxy) and some using an explicit proxy. Barracuda needs two boxes to do this (one for each mode). 8e6 can’t function as a proxy at all so they would need to set up a proxy that then sends the traffic to 8e6.

This problem is easily solved using St. Bernard’s iPrism. St. Bernard offers “mixed mode” filtering which means they can be a transparent proxy and explicit proxy at the same time for different users, machines or protocols. It can be quite handy for organizations with mixed authentication or machine environments or that want granular reporting on web use by terminal server users.

Here is the KB article: iPrism Mixed-Mode Traffic Filtering.

In this case, it looks like iPrism is the best fit.
