Commtouch Zero-Hour Virus Protection

Server-side polymorphic malware has become impossible for traditional AV engines to block, since there are typically thousands of distinct variants, and malware distributors often release hundreds of new variants per hour.

Commtouch® Zero-Hour Virus Outbreak Protection provides a complementary shield to conventional AV technology, protecting in the earliest moments of malware outbreaks, and right through as each new variant emerges.

Signature-less
Signature-less protection is an essential complement to traditional AV technologies, security experts agree. By proactively scanning the Internet and identifying massive virus outbreaks as soon as they emerge, Commtouch's Zero-Hour Solution provides just that: proactive virus blocking that is effective and signature-independent.
Immediate
Commtouch provides proactive virus detection to close the early-hour vulnerability gap during which millions of users are infected. Commtouch's proactive virus detection capabilities ensure users' protection hours before signatures are released.

"Aimed at detecting mass outbreak indicators, Zero-Hour is differentiated from other proactive virus detection technologies by several advantages. First and foremost is the immediate and accurate detection of new outbreaks" - Dan Yachin, IDC.
Proven
Robust and inherently immune to emerging foiling attempts, Commtouch has a proven record of being the first and highest performing among proactive virus control solutions. Commtouch's Zero-Hour Virus Outbreak Protection Solutions are based on RPD technology, which has a track record of protecting million of users globally.

Note: IMail Server was modified to handle the Commtouch scan at the SMTP level, allowing the new "Reject" classification type to occur, rejecting a message before being accepted.
