The following matrix may help to clarify the SEP 14 reference; SES Policies
I believe these particular policies are relevant when SEP 14 is being managed from the Cloud console in a hybrid deployment model.
A Hybrid deployment model now requires a SES licence (SES Enterprise or SES Complete). This deployment model was previously referred to as SEP15
. The term SEP15 is no longer used and it is now referred to as Symantec Endpoint Security (SES).
SEP14 is still available as a standalone product and can be purchased with a SEP-specific licence.
Hope this helps.
