Microsoft Exchange Online Protection (EOP)

Microsoft Exchange Online Protection (EOP) is an email cloud service that provides end users with protection against spam and malware.

EOP, which is available to Exchange Server on-premises shops as well as to Office 365 and hybrid configuration customers, has three service plans:

• EOP standalone – This service is designed for on-premises Exchange mailboxes.
• EOP in Office 365 – This service is designed for Exchange Online mailboxes in the cloud.
• Exchange Enterprise CAL with Services – This service is much like EOP standalone, but also includes data loss prevention, as well as PowerShell remoting administration capabilities.

EOP replaces Microsoft's Forefront Online Protection (FOPE) product.
