Hi,
If you are using Small Business Edition then at SEPM console there will be written "Small Business Edition"
In Enterprise Edition only you see only Symantec Endpoint Protection Manager.
There are many differences between Enterprise Edition and Small Business Edition.
Check this forum article for more details.
