Cloudmark's Global Threat Network Technology Enables Rapid Identification of New Messaging Threats

San Francisco, CA -- Cloudmark, Inc., the global leader in carrier-grade messaging security, today announced that it has been awarded U.S. Patent: 7,373,385, for Cloudmark's Global Threat Network™ technology.

This patented technology, the Global Threat Network system, is the industry's first collaborative threat detection system. The Global Threat Network system consists of 600 million trusted reporting sources, including service provider abuse teams, systems administrators, honeypots and users, who report e-mail messages into the system in real-time. Corroborated feedback from these reporters enables Cloudmark to automatically block new spam, phishing and virus outbreaks within minutes of the original attack.

"Today's sophisticated and fast-moving messaging attacks easily outpace solutions that rely on manual isolation and remediation," said Leon Rishniw, VP of Engineering at Cloudmark. "Only an automated, real-time global threat detection system can offer the accuracy and fast response time needed to effectively combat today's threats."

This pioneering patented technology drives Cloudmark's unrivaled accuracy and rapid response time. With Cloudmark's Global Threat Network technology, threat monitoring is not limited to a single research group in a company, as is the case with other threat detection solutions, but extends to a 24 x 7 network of millions of diverse reporting sources from every country around the world. This feedback is then validated through Cloudmark's Trust Evaluation System™ algorithmic analysis methodology to ensure the highest degree of system accuracy. The combination of Cloudmark's Global Threat Network technology, together with Cloudmark's Advanced Message Fingerprinting™ technology, delivers extremely high filtering accuracy and reduced infrastructure and operational costs to service providers who deploy Cloudmark Authority® software.

"The Global Threat Network is the first and largest trusted collaborative threat detection system in the world," said Rishniw. "This patented technology gives Cloudmark customers unmatched protection against emerging threats and demonstrates Cloudmark's expertise and innovation in the field of messaging security."
