Info Security Products Guide Awards Cloudmark's "Increased Messaging Security for a U.S. ILEC's Subscribers" Winner of the 2006 Best Deployment Scenario Award

Market Wire, August, 2006

Cloudmark announced today that Info Security Products Guide, a Silicon Valley Communications publication and the world's leading publication on security-related products and technologies, has named its submission, "Cloudmark increases messaging security for a U.S. ILEC's 500,000 subscribers," a winner of the 2nd Annual Best Deployment Scenario Award in the anti-spam category. This prestigious award recognizes security vendors with advanced, ground-breaking network security solutions that are helping set the bar higher for others in all areas of information security. The U.S. ILEC messaging security deployment was selected by the editors of Info Security Products Guide based on real world solution deployments making the most positive impact on security in today's highly sophisticated and blended attacks environment.

Info Security recognized Cloudmark for helping the incumbent carrier achieve significant savings in operations expense and greater efficiency in network operations. The service provider experienced significantly lower customer service costs due to fewer complaints as a result of more accurate classification of spam. Also, greatly reducing the amount of spam coming into the network lightened the load on messaging servers, reduced CPU usage, and relieves storage servers of unfiltered spam. In initial trials, the Cloudmark solution also caught ten times as many viruses as the legacy provider.

"Info Security Products Guide's recognition of our deployment of messaging security for a U.S. ILEC further validates that Cloudmark provides best of breed anti-abuse protection to service providers and their subscribers," commented Jacinta Tobin, Vice President of Business Development at Cloudmark. "Deploying successful security solutions that have the highest accuracy and performance translates to tangible cost savings and enhanced services to subscribers, two issues important for all of us serving the carrier market. It is also a testament to the partnership that we create with the service provider in order to ensure a successful deployment and continued high customer satisfaction. "

According to Rick Justice, Chief Technology Editor, Info Security Products Guide, "We award the 'Best Deployment Scenario' to those companies that are able to make a significant difference in the way their customers do business, and to offer a superior level of protection. We were very impressed by the cost savings the Cloudmark deployment was able to generate for its customer, made possible by an overall improvement in securing the network from messaging abuse such as spam, phishing and viruses. Cloudmark has demonstrated its leadership with its innovative technology and proven solutions."

Authority, Cloudmark's carrier-grade solution for messaging security, demonstrates 20 % greater accuracy at stopping spam in head-to-head trials, while consuming 5-20% of CPU utilization, vs. 80-90% for legacy systems. Cloudmark Authority also reduces the volume of mail consuming costly storage space. In analyses of service provider message stores, Cloudmark has verified that as much as 70% of stored messages may be spam, a result of inaccurate filtering by legacy systems, which can lead to a waste of 18-25% of storage space.
