Forefront Protection 2010 for Exchange Server (FPE) implemented in Office 365 data
centers is also responsible for protecting the Exchange Online servers. It takes care of the email
filtering and email handling workloads. FPE can also be implemented as a stand-alone
hosted service to protect an on-premises Exchange server. We will discuss this in greater
detail later in this chapter.
When Forefront is acquired as a stand-alone service rather than as part of Exchange Online,
it is known as Forefront Online Protection for Exchange (FOPE). At the time of this writing,
FOPE is scheduled to be updated, and the next release will be renamed Exchange Online
Email filtering ensures email safety by dealing with possible threats and nuisance within
emails, such as spam mail based on content, spam mail from known or suspicious sources,
and messages that contain potentially dangerous attachments. Email-borne threats still
rank the highest in terms of security risk, and the popularity of mobile devices as a result of
the bring your own device (BYOD) phenomenon serves to exacerbate the problem.
EOP/FOPE forms a layer of separation between Exchange Online and the Internet, and it
accepts and routes email on behalf of your organization. As such, EOP/FOPE is able to
provide email filtering services through the traditional approach of scanning the headers and
contents of inbound and outbound email.
EOP/FOPE is built upon thousands of servers spread across global data centers using a
Microsoft proprietary algorithm to route traffic. In the event that a data center goes ofline,
the algorithm will reroute traffic accordingly. Therefore, your organization's email presence
will benefit from the highest level of redundancy.
We provide a more detailed look at FOPE capabilities in the "Forefront Online Protection
for Exchange" section later in this chapter.
Secure email service is a solution built by a Microsoft partner, Voltage Security, and hosted
in Office 365. This service is known as Exchange Hosted Encryption (EHE). Sensitive
information such as trade secrets, product information, customer data, private health
information protected by the Health Information Portability and Accountability Act (HIPAA), and
credit card information are some examples of sensitive data that needs to be protected. We
cover EHE in detail in the "Exchange Hosted Encryption" section later in this chapter.
