Most of the customers has a very strict policies based on government rules. They need to audit DLP Admins in order to control any mis-usage of DLP products. We can see some audit logs about admin activities but can't see what object has been changed and its before and after settings.
If admin add its email address in any rule as a destination exception, we can't see and control this change.
In summary, we need very detailed audit logs and send them to log management system in CEF format.
This feature is very important for us and looking forward to see in next upcoming release.
