Chapter 1 What’s New for FortiOS 5.0 : Usability enhancements : Fortinet Top Bar
  
Fortinet Top Bar
You can configure the FortiGate unit to overlay a Fortinet status bar on your user’s web pages by going to Policy > Policy > Proxy Options and selecting Add Fortinet Bar and then by adding this Proxy Options profile to a security policy. Whenever a user accesses a web page through this policy, the Fortinet Top Bar is displayed overlaying the upper right corder of the web page.
The top bar can display a user ID if the user has authenticated with the FortiGate unit (in the example the user ID is bdickie). You can select the user icon to sign out of the FortiGate unit.
The top bar can also display other information such as:
Application control violations
Endpoint control enforcement
Your web browsing quota
User ID if the user has authenticated
SSL VPN status and bookmarks
