Having used DLP for many years now it needs a bit of a face lift.
My customers have the following feed back for DLP:
1. Needs to be integrated to the R80 console for on premises appliances and to allow multiple write administrators.
2. Able to define multiple organizations
3. Proximity scanning against multiple lists
4. Scanning for strings/text embedded inside document structures ( ie not visible to users and outside of the body tags)
5. Better incident work flow management, ie a ticketing type system for investigating policy breeches.
6. Link in smart view to download email from the log list without having to open the log entry itself.
7. Ability to create custom categories
8. Improvements in the matching engine to allow matching between subject line and body text, ie Term x in the subject but not in the body.
