Cloudmark Announces Significant Market Traction With Cloudmark Authority for the Apache SpamAssassin Platform

NuVox and domainFACTORY Join More Than a Dozen Service Providers Using the Cloudmark Authority Plug-In for Apache SpamAssassin to Protect Subscribers From Messaging Abuse

ATLANTA, GA--(Marketwire - November 13, 2007) - APACHECON -- Cloudmark, Inc., the global leader in carrier-grade messaging security, shows significant traction with independent and mid-sized service providers with the recent addition of NuVox Communications in the U.S. and domainFACTORY in Germany as new customers. These companies join a growing number of Internet Service Providers (ISPs) and hosting providers now using the Cloudmark Authority plug-in for SpamAssassin™ to improve message filtering accuracy and performance. Customers using Authority for SpamAssassin include Parus Interactive, B2B2C, XS4ALL, ZEROSPAM and Intergenia.

SpamAssassin is the most widely-deployed open source spam filtering solution. Currently, more than 100 million mailboxes worldwide are covered by SpamAssassin and more than 100,000 organizations worldwide have deployed the solution for message filtering. The Cloudmark Authority plug-in integrates into virtually any SpamAssassin environment, leveraging existing policies, databases and rules.

"The conventional commercial development model for the open source community has often involved bundling open source products and services, then re-selling them as a commercial solution," said Justin Mason, project committee member for Apache SpamAssassin. "Companies like Cloudmark are taking a different approach by leveraging the advantages of the existing open source SpamAssassin platform and giving organizations the advantages of their commercial product without the need to uproot an existing messaging environment. Enhancing protection against email-borne threats while eliminating the need to change infrastructure is critical to companies that have invested in the SpamAssassin platform."

Cloudmark Authority offers the industry's fastest and most accurate spam, phishing and virus protection, achieving more than 98 percent accuracy with near-zero false positives. It utilizes a combination of Advanced Message Fingerprinting™ algorithms and real-time corroborated feedback from the Global Threat Network. Cloudmark Authority rapidly detects messaging abuse using an in-memory cache of verified fingerprints that updates every 45 seconds to catch the latest threat outbreaks. Cloudmark's solution cuts CPU/server requirements and frees IT resources by reducing administrative time.

"What attracted us to Cloudmark's solution in the first place was the seamless integration into Apache SpamAssassin," said Keith Coker, chief technology officer at NuVox, a voice, data and security services company with 90,000 business customers. "We were impressed with the simplicity of the process as our team was able to quickly deploy the solution. Since the deployment of Cloudmark Authority, we have witnessed a significant dip in the amount of spam reaching our subscribers' inboxes. We are excited to have another way to protect our subscribers from the risks of viruses and malware."

"Service providers, like NuVox and domainFACTORY, have seen at least a 20 to 50 percent boost in message filtering accuracy with Apache SpamAssassin by using the Cloudmark Authority plug-in," commented Jamie de Guerre, CTO of Cloudmark. "These companies join Cloudmark's growing list of independent and mid-market service providers who are benefiting from significantly improved message filtering and infrastructure utilization."
