Overview of Data Loss Prevention

The Data Loss Prevention (DLP) feature secures your organization’s proprietary information and

intellectual property and enforces compliance with government regulations by preventing users from

maliciously or unintentionally emailing sensitive data from your network. You define the types of data

that your employees are not allowed to email by creating DLP policies that are used to scan outgoing

messages for any data that may violate laws or corporate policies.
