Published 24th November 2008

Cloudmark, Inc., a global leader in carrier-grade messaging security, today announced that Cloudmark Authority® has been selected by China’s No. 1 Web portal, Sohu.com, as the company’s primary anti-spam solution for their email services. Sohu selected Cloudmark Authority due to its high accuracy, ease of use, manageability and ability to scale to meet the needs of Sohu’s large user base. In trials, Cloudmark Authority was proven to successfully block 98 percent of inbound spam, phishing and virus attacks with near zero false positives.

Following an extensive testing phase, Sohu selected Cloudmark Authority and deployed the solution prior to the start of the Beijing Olympic Games in anticipation of unusually high volumes of Game-related spam messages. The solution combines highly sophisticated Advanced Message Fingerprinting™ technology based on high performance algorithms and a Global Threat Network consisting of trusted reporters in over 190 countries to provide security intelligence and filtering at all points in the messaging infrastructure. Cloudmark’s Advanced Messaging Fingerprinting technology enables Sohu extremely efficient scanning, utilising only a fraction of the CPU of traditional rules and heuristics-based solution.

Cloudmark’s language-agnostic threat analysis is able to keep the inboxes of Sohu users clean from both Chinese and non-Chinese language spam in any protocol or format. Users are instantly protected from the latest attack as Cloudmark Authority is automatically updated every 30-60 seconds with new threat data.

“Since implementing Cloudmark, Sohu has experienced immediate and significant resource savings in the areas of CPU, storage, Internet network resources, administrative and customer support,” said Qiu Jingbo of Sohu. “Our decision to deploy Cloudmark has resulted in a significant improvement in subscriber satisfaction and enhancement of our company brand. We are extremely pleased with the results and look forward to working with Cloudmark to continue delivering the best e-mail experience for our customers.”

“With the opening of our offices in Beijing and Hong Kong in May of 2007, Cloudmark demonstrated its commitment to providing service providers in China with powerful messaging security solutions and ongoing support against the ever-growing spam problem,” said David Somerville, regional vice president of Cloudmark. “Our partnership with Sohu further solidifies our dedication to this market and marks an important milestone for Cloudmark’s growth, development and leadership in China.”
