Viruses, spam, and phishing attacks are all threats to your e-mail environment. With Microsoft Exchange, you have choices in how you protect your e-mail environment. You can choose Microsoft Exchange Hosted Filtering, which protects your messaging environment in the cloud. Or you can choose the Exchange Server 2007 Edge Transport server role, with Microsoft Forefront Security for Exchange Server, for protection in your network perimeter. In addition to protection from external threats, Forefront Security for Exchange Server also offers antivirus protection for Exchange servers within your local area network (LAN).
Exchange Hosted Filtering: Virus and Spam Protection in the Cloud
Microsoft Exchange Hosted Filtering is a fully managed e-mail security service that helps stop viruses and spam before they reach your network. Exchange Hosted Filtering provides reliable spam filtering with high capture rates and virtually no false positives. In addition, the service helps provide zero-day virus detection and blocking, and flexible filter options that help you enforce corporate e-mail policies for inbound and outbound mail.
Exchange Hosted Filtering provides enterprise-class hosted services for e-mail security and management with service performance backed by service level agreements (SLAs). Exchange Hosted Filtering gives you a convenient way to improve the reliability and scalability of your existing messaging infrastructure.
How Exchange Hosted Filtering Works
With just a simple MX record configuration change, Microsoft Exchange Hosted Filtering 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 or 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.
Exchange Server 2007: Virus and Spam Protection in the Perimeter
Microsoft Exchange Server 2007 features a server role that helps you safeguard the messaging infrastructure for your organization. The Edge Transport Server role provides virus protection and spam filtering at the network perimeter—before dangerous data can affect your network.
The Edge Transport server role can be deployed with Microsoft Forefront Security for Exchange Server to provide a comprehensive antivirus and antispam solution for your organization. Automatic updates can be configured for both virus and spam filtering, and custom filters can be centrally configured to help you enforce corporate policies. The Edge Transport server is fully configurable to meet the unique needs of your organization.
Understanding the Exchange Edge Transport Server Role
The Exchange Edge Transport server role offers the best of both worlds. First and foremost, it provides added security in the form of an e-mail gateway that is deployed in the perimeter of your network. In addition, it provides you with consistent administration experiences, the Exchange Management Console and the Exchange Management Shell, which you might be used to with the other Exchange Server roles.
Furthermore, the Exchange Edge Transport server role allows you to use the information that already exists in your network to better protect your network. User-created Outlook Safe Lists are propagated to the Edge to help ensure that your users receive their business-critical e-mail and recipient filtering with optimal security using the information stored in Microsoft Active Directory. The Edge Transport server role is a highly available, enterprise class SMTP mail gateway.
