The following how-to guide will take you through the steps to configure DLP fingerprinting on the FortiGates.
Before we begin we need to confirm two things.
Firstly, the FortiGate model you are configuring has a storage drive. Models like the FG80C have no storage so DLP fingerprinting won't work.
Secondly DLP has been enabled in the web-gui. If it's not you can enable it via the CLI with the following commands:
config system global
set gui-dlp enable
end
For FortiGates running 5.2 you'll need to goto Security Profiles > Advanced > DLP Fingerprinting. If you're running 5.0 it will be found under Security Profiles > DLP > DLP Fingerprinting.
