Deep Discovery Email Inspector evaluates a file or data against a set of Data Loss Prevent (DLP) rules in policies. DLP rules determine files or data that requires protection from unauthorized transmission and the action that Deep Discovery Email Inspector performs after detecting a transmission.
You can start to configure DLP rules after you have configured data identifiers and organized them in DLP templates.
Note:
By default, Deep Discovery Email Inspector applies DLP polices on outgoing email messages based on the recipient and sender settings.
