possible DLP violation in an outgoing message. Different actions can be assigned for different violation
types and severities.
Primary actions include:
•
Deliver

Drop

Quarantine
Secondary actions include:
•
Sending a copy to a policy quarantine if you choose to deliver the message. The copy is a perfect
clone of the original, including the Message ID. Quarantining a copy allows you to test the RSA
Email DLP system before deployment in addition to providing another way to monitor DLP
violations. When you release the copy from the quarantine, the appliance delivers the copy to the
recipient, who will have already received the original message.

Note
These actions are not mutually exclusive: you can combine some of them within different DLP policies
for various processing needs for different user groups. You can also configure different treatments based
on the different severity levels in the same policy. For example, you may want to quarantine messages
with critical DLP violations and send a notification to a compliance officer, but you may want to deliver
messages with low severity levels.
