I have THE BIGGEST PROBLEM!!!
Any user can convert any file into jpeg, png, gif and other extensions. DLP Endpoint 9.3.4. do not work with image files. Besides, DLP Endpoint 9.4 what will be in may 2015 will not work with image files. Or user can change extension from any file to unknown, for example: if change 1.doc to 1.000 - DLP Endpoint 9.3.4 do not see or block the sending of this file.
And my question is:
How can I do Protecrion Rule "Block all image sending"?
