Cloudmark Authority Chosen to Safeguard Users of Popular QQMail Service against Spam, Viruses and Phishing Attacks; New, Localized Cloudmark Desktop Plug-in Available for Tencent's Email Client 

SAN FRANCISCO -- Cloudmark, Inc., the global leader in carrier-grade messaging security, today announced that Tencent, China's largest and widely used Internet service portal, has selected Cloudmark Authority[R] to protect its QQMail Web-based email service from spam, viruses and phishing attacks. Cloudmark also announced the availability of a new, localized Cloudmark Desktop plug-in for Tencent's popular client software. This is yet another milestone in Cloudmark's global momentum. Cloudmark opened regional offices in China in 2007 to focus on this fast-growing market.

Spam volumes in China have reached epidemic proportions and continue to increase, with recent research estimating that 70 percent of all domains used in spam have a .cn top-level domain. In a continuing effort to provide stable, secure, fast and convenient email services free of charge to QQ users, Tencent has sought to combat these messaging threats by soliciting the services of Cloudmark. According to Tencent, they also expect improvements in scanning accuracy and false positive rates, as well as a strengthening of QQMail's brand by enhancing the overall user experience.

Cloudmark Authority is a carrier-grade software solution that delivers the industry's fastest and most accurate spam, phishing and virus protection. Cloudmark Authority uses a unique combination of Advanced Message Fingerprinting[TM] and real-time threat reporting from the Cloudmark Global Threat Network[TM], consisting of trusted users in 190 countries around the globe. Cloudmark Authority integrates seamlessly into QQMail's existing user feedback system for reporting messages identified as spam.

Cloudmark Authority offers industry leading accuracy, requires significantly less processing power than competitive solutions and lowers CPU requirements by up to 90 percent. Furthermore, Cloudmark Authority frees network resources, lowers storage requirements and delivers an immediate improvement in the email user experience.

"Internet service providers in China are facing an unprecedented challenge as they seek to protect their users from messaging threats," said David Somerville, vice president and general manager of the Asia Pacific region, of Cloudmark. "Tencent's selection of Cloudmark validates both the effectiveness of our messaging security solutions and our commitment to the Chinese market. We look forward to working with Tencent to combat spam and create a high-quality email experience for its QQMail users."

Introducing Cloudmark Desktop[TM] for Tencent's email client

Cloudmark Desktop plug-in for Tencent's email client is the first product developed by Cloudmark that exclusively targets China's fast-growing desktop security market. The Cloudmark Desktop plug-in is a lightweight application that will appear as a simple toolbar directly on the email client.
