Cloudmark teams with Zone Labs in pacesetting antispam, personal firewall partnership

Users benefit from end-to-end desktop protection from crippling spam and the threats posed by hackers, data theft and malicious code

San Francisco, October 21, 2003 - Cloudmark™ Inc. and Zone Labs,® Inc. are pairing to provide consumers and businesses the most effective protection from spam, worms, Trojan horses and spyware. Zone Labs, the most trusted provider of endpoint security solutions, will exclusively bundle SpamNet, Cloudmark's easy-to-use email add-in powered by more than 600,000 users, with its ZoneAlarm® Pro and ZoneAlarm Plus personal firewall solutions. This first of its kind antispam/personal firewall partnership introduces Cloudmark SpamNet to Zone Labs' broad user base, offering Zone Labs customers access to Cloudmark's powerful and unique SpamFighting network.

"The inclusion of antispam capabilities in firewalls is another step towards a modular security architecture," said Brian Burke, research manager, security products at IDC. "Enterprise and consumer customers will increasingly look for security products that integrate various security features such as firewall, antivirus and antispam, with centralized management. The Cloudmark/Zone Labs deal is a step in the right direction."

The Cloudmark/Zone Labs partnership offers consumers a combined solution from two best-of-breed providers. Zone Labs' award-winning security products protect more than 25 million Internet users and 800 enterprise customers from the threats posed by hackers, data theft and malicious code. Cloudmark carries the majority of mindshare among end-users as the most accurate and trusted antispam solution available.

"Zone Labs customers rely on our ground-breaking solutions to fight Internet-borne threats of increasing complexity," said Frederick Felman, vice president of marketing at Zone Labs. "The combination of Cloudmark and Zone Labs solutions allows customers to fully enjoy their online experience without compromising security or privacy."

Cloudmark's real-time peer-to-peer architecture was the reason not one of its more than 600,000 SpamFighters was infected with the recent Sobig virus which harmed millions. ZoneAlarm Pro combines the strongest security, ease of use and powerful online privacy protection, including ad blocking and cookie control capabilities, with simple set-up for networks, including wireless networks. ZoneAlarm Plus provides Zone Labs' award-winning firewall protection and a high degree of control in an easy-to-use package for home and small business users, especially those who are 'firewall purists'.

"We are extremely discerning when choosing industry partners, and were very pleased to see Zone Labs exhibit that same key selectiveness in the marketplace," said Karl Jacob, CEO for Cloudmark. "The perfect technology match, Cloudmark and Zone Labs fuel one another's prominent industry reputation and set the precedent for protecting users across the world from relentless spammers and costly data thieves."

SpamNet is the first and largest group of people – more than 600,000 – whose members collaborate in real-time to fight spam. Because of its community based peer-to-peer filtering model, SpamNet keeps over 95 percent of spam out of users' inboxes automatically, so spam doesn't waste time and money. Zone Labs will immediately bundle SpamNet with the online sales of ZoneAlarm Pro and ZoneAlarm Plus. Existing Zone Labs customers will receive an offer of a special, discounted price to add SpamNet to their Outlook email clients.
