Chapter 7 Firewall for FortiOS 5.0 : Firewall objects : Security profiles : Application Control
  
Application Control
Application Control is designed to allow you to determine what applications are operating on your network and to the also filter the use of these applications as required. Application control is also for outgoing traffic to prevent the use of applications that are against an organization’s policy from crossing the network gateway to other networks. An example of this would be the use of proxy servers to circumvent the restrictions put in place using the Web Filtering.
