Good afternoon,
I think you maybe a bit confuse about the SEP and the DLP endpoint agent so i will hope to clean this up. Symantec Endpoint Protection and DLP on the Endpoint have different agents and also different use cases.
SEP focuses on protecting the endpoint from malware, viruses and other types of infections. DLP focuses on the protecting confidential data from leaving the environment via removable storage, web, and other vectors.
They are seperate agents so you cannot leverage the SEP agent to provide the DLP protection and vice versa.
Take a look at this video that I did: https://www.youtube.com/watch?v=0VLQTm48eoI while a bit old is still mostly current
