dlp with remote access software

[Burhanripl]

Dear all,

Please help me.

We want to block transfer of all files with extension ".cs". We have achieved it successfully using dlp on http, https, ftp and smtp protocol. But one remote access software(like team viewer) is a necessary for us. We cannot block the team viewer totally. 

But we are unable to block the .cs file transfer with team viewer file transfer. Fortinet support person suggested that, team viewer encrypts the files while transfer process hence, it can't be scanned for dlp. We tried ammyy admin too, but dlp does not scan that either. 

So, my question is, if anyone knows any remote access software on which fortigate dlp works well?

It it is, then i can block all other remote access software and allow only that particular remote access software.

Regards
