Chapter 1 What’s New for FortiOS 5.2.1 : Usability Enhancements : New Feature Settings Preset
  
New Feature Settings Preset
A new preset, UTM, has been added to the Feature Settings, which are set either using the Features widget or by going to System > Config > Features. This preset turns on the following features: antivirus, web filtering, application control, and end point control. This preset is the default setting for FortiGate models 200 and below.
The preset formerly known as UTM, which turns on all features, is now called full UTM.
