We currently have a Cymphonix DC30c device that does not sit in line and is used as an internet proxy (configured through Internet Options on client computers) that is approaching end of life. I'm not a big fan of it being out of line because of the client configuration required, the per user licensing, when out of line it doesn't give real-time usage stats, etc.
Cymphonix has a good trade-up program but I wasn't hugely impressed with the current device even though the newer model devices do sound nice.
Does anyone have any recommendations? I am looking for something that may sit in-line between our ProCurve "users" switch and our core routers. We have around 80 users. We are looking for something that can black list specified websites, perform reporting on bandwidth usage, protect against internet born threats, etc.
