EDM detection rules on an Endpoint Agent can cause network performance issues.
[DLP Endpoint Prevent] 14.0 to 15.0
To reduce the number of messages, we recommend creating a compound rule for the Endpoint policy.

The DCM detection rule will work as a short circuit. Only the messages that match the DCM will be sent to the Server.
