Client-based antivirus software is not enough. What if a virus is released after the nightly update? What if a user’s computer fails to update properly?

The best defense against viruses is to prevent them ever from reaching the user’s mailbox. That’s where Sybari Antigen for Exchange Server comes in. Antigen scans email and public folder posts in real time, before they are written to the Exchange database. If they are infected, they are either cleaned, deleted or quarantined immediately. No user is exposed to their harmful payload.

Besides scanning for known viruses, Antigen can be configured to scan for attachments containing potentially harmful code — such as vbscript, java, and application programs.

When a new virus is released, not every antivirus vendor releases a patch for it at the same instant. Antigen includes scanning engines from four vendors — all of which can be active simultaneously — Network Associates/McAfee, Computer Associates, Sophos and Norman Data Defense. Of course, Antigen provides scheduled, automatic updates, but it also allows you to perform a manual update as soon as one is available for any of the engines. Once the update is downloaded, all users are protected — no distribution to clients is needed.

Despite all this power, Antigen is simple to manage and barely impacts the performance of your Exchange servers. For more information, see
