Cloudmark Provides Industry-Leading Messaging Security to domainFACTORY With Cloudmark Authority for Apache SpamAssassin™

Cloudmark Authority Improves SpamAssassin Filtering Accuracy by 22 Percent and Message Processing Speed by 200 Percent for domainFACTORY

SAN FRANCISCO, CA--(Marketwire - October 30, 2007) - Cloudmark, the global leader in carrier-grade messaging security, today announced that domainFACTORY has deployed Cloudmark Authority on the Apache SpamAssassin™ platform to better protect its subscribers from spam, phishing, viruses and malware. domainFACTORY offers e-mail, Web hosting and server solutions for over 90,000 customers with over 400,000 mailboxes in Germany. In deploying Cloudmark, domainFACTORY expects to see a dramatic reduction in the level of spam, phishing, viruses and other threats, which in turn, will lead to improved customer satisfaction and savings in infrastructure and operational costs.

Cloudmark Authority enables service providers to significantly increase filtering accuracy while cutting CPU/server requirements and the need for on-going rules administration. Prior to implementing Cloudmark Authority on SpamAssassin, domainFACTORY found its message filtering accuracy fell below 80 percent. After deploying Cloudmark Authority in its test environment, domainFACTORY's message filtering accuracy jumped to 96-98 percent. Additionally, domainFACTORY has experienced a dramatic improvement in their message processing rate, which went from 20 messages per second to over 60 messages per second per server. The improved performance will subsequently enable domainFACTORY to reduce the number of anti-spam servers it uses by 66 percent.

Cloudmark Authority is able to achieve this accuracy and performance through a combination of Advanced Message Fingerprinting™ algorithms and real-time corroborated feedback from the Global Threat Network. Cloudmark Authority on SpamAssassin rapidly scans messages for all forms of abuse, including viruses, spam and phishing, using an in-memory cache of verified fingerprints that is updated every 45 seconds. As the Cloudmark threat database is automatically updated, domainFACTORY no longer needs to manually write new message filtering rules, which had previously been a very time consuming and ineffective method of tackling anti-abuse.

Cloudmark Authority for SpamAssassin incorporates an integration layer that allows it to seamlessly plug into virtually any SpamAssassin environment, enabling the solution to be deployed in as little as half an hour. There is no need for development resources or any impact on the existing infrastructure.

"A major headache for any new IT deployment is the associated disruption of service, but with Cloudmark this was not an issue," commented Jochen Tuchbreiter, Managing Partner at domainFACTORY. "We could fully leverage our existing SpamAssassin platform. And installing the Cloudmark Authority plug-in was surprisingly painless -- within hours of receiving the software, we had it integrated into our environment and was already showing positive results."

Cloudmark has a long history with the open source community through Vipul's Razor. Developed by Cloudmark's founder and chief scientist Vipul Ved Prakash, Razor was the first messaging security plug-in for the SpamAssassin platform.

"Winning the war against spam, viruses and malware is a key driver of customer retention and satisfaction," commented Neil Cook. "Cloudmark Authority for SpamAssassin offers carrier-grade anti-spam and anti-virus protection that also dramatically saves operational and infrastructure resources. Authority's proven high accuracy has made it the choice of the leading e-mail service providers in Germany."
