Protect your messaging infrastructure from internal and external threats with accurate,
multi-layered filtering technologies.
Message Protect incorporates multiple filters to actively help protect businesses’ inbound and
outbound e-mail from spam, viruses, phishing scams, and e-mail policy violations.
The service employs multilayered defenses to help block e-mail malware from reaching your corporate
gateway. In addition, the service provides both rich tools for writing rules to help enforce corporate
and regulatory policies governing e-mail usage and disaster recovery tools to queue mail for delivery in
the event of an e-mail server outage.
Message Protect is deployed over the Internet, which helps minimize up-front capital investment, free up
IT resources to focus on value-producing initiatives, and mitigate messaging risks before they reach the
corporate network. Message Protect provides a comprehensive set of SLAs backing network performance and
spam/virus filtering effectiveness.
How it Works
With just a simple MX record configuration change, Message Protect can be up and running quickly. There
is no hardware to provision; no software to buy, install or configure; and no expensive training required
for your IT staff.
Furthermore, there is no need for you to change or modify your existing e-mail infrastructure or even to
install and maintain any new hardware or software. The heart of Exchange Hosted Filtering is a distributed
network of data centers located at key sites along the Internet backbone. Each data center contains
fault-tolerant servers that are load-balanced from site to site and from server to server. In the unlikely
event that one data center is unavailable, traffic can be easily routed to another data center, minimizing
the chances of any interruption to the service. Microsoft algorithms analyze and route message traffic
between data centers to help ensure secure and timely delivery.
Messages not blocked by blacklisting are fingerprinted to detect
matches with known spam message characteristics. Fuzzy fingerprinting
technology leverages knowledge gained from filtering mail for the
entire customer base. The fingerprinting database aggregates data
from all spam blocked by the system allowing the fingerprinting
process to become more intelligent and refined as more mail is processed.
Message characteristics we evaluated and scored include:
- Formation of headers (i.e., Message-ID, Received, random characters)
- Originating mail server
- Originating mail agent
- From and SMTP From address
Most customers choose to quarantine messages identified as spam
outside their network. Quarantined messages are stored and deleted
after 15 days. Customers can review quarantined messages and retrieve
improperly blocked messages through a Web-based tool.
As an alternative to quarantining messages, MEHS also allows spam
to be sent through to customers. When Message Protect forwards spam,
it can modify the message to flag it for internal review. Modifications
- Inserting an X-header for filtering inside the perimeter
- Inserting a new subject line message (i.e., < This is spam >)
- Directing spam to an internal SMTP mailbox
Our anti-virus solution leverages the benefits of the MEHS network
architecture, ensuring that messages are delivered reliably, securely,
and free of harmful content. The following diagram illustrates how
the system works:
Multi-Engine Virus Scanning
Message Protect employs a layered approach to virus scanning. While
many companies install and run anti-virus software on users' desktops
and gateway servers, the fast-moving nature of virus transmission
today requires a more rapid response than desktop and gateway solutions
Outbound Virus Scanning
Even when there is no regulatory concern, policy enforcement of inbound and
outbound communication makes good business sense. A corporation's most important
asset is its intellectual property, and it is critical to protect it through policy
management and enforcement.
The policy enforcement functionality allows messages to be blocked by:
- Specific words and phrases in the subject and body of the message
- Message size
- Number of recipients
- Specific To: and From: addressee
- Specific domain(s)
