Microsoft has presented Antigen for Exchange, a solution to stop viruses and other malicious content from reaching a corporate network, as well as containing internal outbreaks.
There are also three other Antigen products:
Antigen for SMTP Gateways provides similar features for Windows Server systems running a mail server.
Antigen Spam Manager offers anti-spam and content filtering services to both Windows Server and Exchange Server setups. Microsoft is offering all three utilities in a single package called Antigen Messaging Security Suite.
Antigen Enterprise Manager, meanwhile, provides a centralized application for managing Antigen-enabled servers. From there, administrators can configure settings and setup content filtering rules. Microsoft is additionally making available a management pack plug-in for Microsoft Operations Manager 2005.
