Earlier this year Microsoft acquired Sybari, maker of anti-virus and anti-spam solutions. FrontBridge's solutions do include anti-virus and anti-spam offerings but unlike Sybari, FrontBridge provides managed services. In addition to anti-virus and anti-spam services the acquisition will bring Microsoft the capability to offer email encryption, email policy enforcement for regulatory standards compliance, and email archival services.
Microsoft posted a statement regarding the future of Exchange Server in light of their intention to acquire FrontBridge . The company said that, "Long term, we expect you to be able to chose whether you want an on-premise or hosted e-mail solution. As part of enabling that vision, we see Exchange Server as software that can be consumed as a product to run on-premise or as a service that can be hosted for a customer on their behalf. By having all our capabilities available as a product and as a service, we will be able to provide greater value to a larger number of customers."
