Data loss prevention (DLP) scans data that’s posted over HTTP and HTTPS. Applications that use custom protocols over HTTP are not supported.
Some parts of these applications do not generate DLP scan results. This is especially the case if these applications use a custom protocol.

If you want to block these applications in your enterprise, you can configure the application domain in a custom list and associate it to a policy with the block action. If your enterprise uses these applications and they require DLP support, can get you in contact with a partner who can provide a cloud access security broker (CASB) solution for these applications.
Note: DLP is currently in beta. For more information about DLP, see Data loss prevention.
