This video provides and overview of BlackBerry Email Protector.
Email Protector allows you to automatically apply file-level encryption, user access control and digital rights management to outbound email attachments. These security settings are set by the system administrator and applied programmatically with no impact on the email sender.
Email Protector can also be configured to work with your Data Loss Prevention (DLP) system, applying file protections based on your existing DLP rules. This solves the problem of how to protect outbound email attachments that have been identified as sensitive by your DLP system.
