I inherited a Symantec DLP instance about 3 years ago. Learning curve was kind of steep I'm still learning new things and tricks. Setting up and maturing the processes was probably one of the tougher parts but once you got everything configured and running modifying and changing policies is pretty straight forward. Another downside was the need for a physical Oracle Database server for the backend. I keep getting told support for virtualization is coming but their support says its still not supported.
