Block Skype File Transfer with SWG

Dear all,

 

under Access Policy -> Secure Web Gateway -> Applications, there were only skype, login, update for Instant Messaging category. Latest database downloaded for v12.

 

Would like to ask if anyone has this requirement of blocking only file transfers on Skype but allow voice and chat functions.

 

There are other ways to do this such as editing the end point's registry but would like to know blocking of transfer function can be done at SWG level.

 

Thanks!
