Microsoft Antigen server security products help businesses protect their e-mail and collaboration servers from viruses, worms, spam, and inappropriate content.

Many of today's viruses and worms are designed by criminal hackers to rapidly infect millions of computer systems across the world through the Web and e-mail. In addition to e-mail threats, an evolving ecosystem of viruses, worms, and blended threats are finding new ways to propagate inside corporate networks--including via portals and instant messaging applications. As a result, messaging and collaboration infrastructure is a critical focal point for businesses in the fight against malicious software.

Antigen server security products provide comprehensive protection for e-mail and collaboration environments with:
￭ Advanced Protection: Multiple scan engines at multiple layers throughout the e-mail infrastructure provide improved protection against e-mail threats.
￭ Availability and Control: Tight integration with Microsoft Exchange and Windows-based SMTP servers maximizes availability and management control.
￭ Secure Content: Helps organizations eliminate inappropriate language and dangerous attachments from internal and external communications.

To prevent infection and improve spam detection, Antigen e-mail security products combine the strengths of multiple, industry-leading technologies to uncover the latest e-mail threats and spammer tactics. The Antigen email server security products provide complete server-level protection and will help you easily protect your email infrastructure at multiple points in the network to prevent productivity loss and downtime.
