Well the EPS includes Sharepoint but the EPSP or the Endpoint Protection Suite Plus includes both the File System/Exchange Server Security along with AntiSpam.
There may be in the future be some availability to upgrade to this product but for now the EPS is the only product that is provided for the EDU.
The Exchange sits on the Exchange Server and you would need to check the registry of the Exchange Server and the Anti-Spam sits as an Add-On to say Outlook. Your more than welcome to have a look on the EPSP user manual to read more about this.
Kind Regards
