The complexity and velocity of today’s outbreaks are overpowering many SpamAssassin implementations, which often cannot maintain high detection rates without incurring too many false positives. To cope, IT managers are investing more and more time in tuning SpamAssassin rules, with diminishing results.
Commtouch, with its patented Recurrent Pattern Detection™ (RPD) technology, allows SpamAssassin-based email filtering solutions to benefit from the SpamAssassin infrastructure along with the most advanced and leading technology to block spam and zero hour virus outbreaks.
Commtouch offers a SpamAssassin plug-in for its Anti-Spam and Zero-Hour Virus Outbreak Protection technologies. The plug-in is a software module that interfaces between SpamAssassin and the Commtouch detection engine. Messages are passed to the Commtouch engine and the results are converted into SpamAssassin scores. Embedding the Commtouch technology allows existing SpamAssassin systems to simultaneously increase accuracy and decrease the amount of resources required for maintenance, with an easy and fast integration effort.
Commtouch's RPD technology is a service "in the cloud" that works by analyzing massive volumes of Internet traffic in real-time to identify recurring malware and spam patterns. The Commtouch Plug-in then queries and retrieves spam and malware classifications from the Commtouch Detection Center in real-time. The result is instant protection from new outbreaks without any lag in updates - hours, or even days, before most solutions. RPD has demonstrated sustainability over many years, while other, content-based filtering methods have been overwhelmed by new spammer or malware tricks.
