Anyone tried to block proxies applications such (Kproxy, psiphone, ZenMate ...etc), i try to do that using AppSecure & IDP with the new Junos version 12.3x48 & 15.1 without any positive results, after investigation I wonder !!! because i found those applications under web category on the AppSecure signatures, is it correct !!! the AppSecure can just block the http request not the applications itself !!!
Appsecure and App Id has lot of enhacment in latest releases, they just don't go over to HTTP/HTTPS request but infact goes into deep packet level inspection to identify the application to allow/block traffic .
I hope this helps. if there is anything specific not working then we can definately start a new thread of discussion.
