San Francisco—November 10, 2009—Cloudmark, Inc., the global leader in carrier-grade messaging security, today announced that Network Solutions', a leading provider of Web solutions for small businesses, has selected Cloudmark to provide spam, phishing and virus protection for Network Solutions' more than 2.2 million email subscribers. By using Cloudmark Gateway, a high-performance edge mail transfer agent (MTA), in conjunction with Cloudmark Authority, Network Solutions' hosted email customers will receive the industry's fastest, most flexible, and most accurate edge message filtering solution.

With the recent re-launch of Network Solutions' business class email solution, the company needed an advanced messaging solution that would offer increased spam and virus protection for hosted email customers, as well as increased operational efficiency.

"For small businesses, email is a lifeline to their customers so it is very important to us that we offer our customers the most effective spam and virus protection software in the industry."

As a high-performance MTA, Cloudmark Gateway with Cloudmark Authority prevents unwanted email from impacting user inboxes and messaging infrastructure by performing intelligent protocol and content filtering at the perimeter of the hosted environment. The result is a solution that significantly reduces infrastructure needs and improves the quality of service offered to customers.

In addition, due to a unique combination of Advanced Message FingerprintingTM technology and real-time corroborated feedback from Cloudmark's Global Threat NetworkTM system, Cloudmark detects messaging abuse with approximately 98 percent accuracy and near-zero false positives, while delivering the highest level of protection against new threat outbreaks and attacks.
