Application Control provides a solution for setting policy based rules for application signatures. Application Control policies include global App Control policies, and App Rules policies that are more targeted. As a set of application-specific policies, Application Control gives you granular control over network traffic on the level of users, email users, schedules, and IP-subnets. The primary functionality of this application-layer access control feature is to regulate Web browsing, file transfer, email, and email attachments.
