Virus protection
"Viruses continue to be the single most destructive threat to email."
Enterprises invest heavily in anti-virus security for end-user desktop systems and servers. Yet they still struggle to keep up with the number of viruses, trojan horses and worms that threaten to corrupt corporate data and shut down operations.
Combatting these emerging threats requires a tiered anti-virus strategy; content on servers and desktops must be scanned as it enters an organisation through email. Security experts suggest a defence-in-depth strategy by using anti-virus technology from multiple vendors.
Virus Protection at the Mail Gateway
MXtreme augments your existing virus protection by scanning all inbound and outbound messages for known viruses using the Kaspersky Anti-Virus engine. Kaspersky Anti-Virus is one of the most highly-rated virus detection engines and automatically provides updates for protection against the latest threats.
MXtreme not only blocks known viruses but can also deal with unknown threats by allowing you to set attachment controls and content filters. In addition, MXtreme filters for malformed messages - a common practice of virus writers that hides infected attachments within a message to slip past your anti-virus defences.
In December 2003, one MXtreme customer blocked 41,000 instances of MyDoom within the first 24 hours of the virus outbreak. It was automatically quarantined by MXtreme even though an anti-virus signature had not yet been developed.
Policy Control and Attachment Handling
MXtreme provides comprehensive policy controls with rich disposition options. These capabilities are extended to attachment control and anti-virus scanning. Administrators have numerous options for handling inbound and outbound messages. Built-in controls enable infected messages to be filtered, deleted or quarantined, attachments to be dropped, and subject headers within the message to be modified.
MXtreme can also be configured to send messages to administrators, end-users or senders to notify them that a virus was found within an email message or attachment.
