ZoneAlarm Security Suite Now Includes MailFrontier Desktop to Combat Email Phishing Fraud and Spam

Palo Alto, Calif. – November 9, 2004 – MailFrontier™, a pioneer in email security and leading provider of anti-spam and anti-phishing solutions, today announced an OEM agreement with Zone Labs®, a Check Point® company (Nasdaq: CHKP). ZoneAlarm® Security Suite 5.5, the latest release of ZoneLabs’ Internet security solution, has added the award-winning anti-phishing and anti-spam technology of MailFrontier Desktop™ to protect consumers and small business users from a wide range of Internet-borne threats posed by online phishing fraud and spam.

“MailFrontier’s anti-phishing and anti-spam features further enhance the ZoneAlarm Security Suite with the critical technologies required of a premier integrated security solution,” said Frederick Felman, vice president of marketing, Check Point’s Zone Labs division. “The MailFrontier Desktop technology allows Zone Labs customers to stay a step ahead of resourceful, profit-driven thieves with a powerful, easy-to-use method for thwarting new email threats. MailFrontier was the natural choice for comprehensive and effective anti-phishing and anti-spam technologies.”

“Zone Labs’ selection of MailFrontier represents a milestone in our market growth strategy and we look forward to protecting Zone Labs customers with a comprehensive email security solution,” said Anne Bonaparte, president and CEO of MailFrontier. “MailFrontier’s anti-phishing and anti-spam technology not only extends the value of the ZoneAlarm Security Suite, but it also expands our SMART Network contributing to our threat response time and ability to stay ahead of new email threats.”

MailFrontier Ecosystem Doubles Power to Combat Real-Time Email Threats
MailFrontier uses advanced spam filters and other technologies to check email as it comes in, and divert spam mail to the “Junk Mail” folder. Fraudulent phishing emails are put in a separate “Fraudulent Mail” folder so users are protected and informed. If an email gets through that isn’t wanted, users can click “Junk” to delete it, train the MailFrontier solution to match individual preferences, and contribute a vote against spam to the real-time response network, MailFrontier SMART Network™.

The extension of MailFrontier technology, via the broad deployment to ZoneAlarm Security Suite users, will more than double the MailFrontier SMART Network of users that are automatically engaged in detecting new threats. The MailFrontier SMART Network, combined with leading technology, translates into instant effectiveness at the moment of deployment and stays effective as threats change.

• Phishing and Fraud Protection uses patent-pending technology to identify and isolate fraudulent emails designed to lure users into dangerous activities. Phishing and other potentially fraudulent emails are sent directly to a Fraudulent Mail folder.  Users can forward these emails to MailFrontier to help eradicate fraud.

• Spam Filter saves users time, effort, and bandwidth by automatically preventing unwanted, inappropriate and dangerous messages from arriving in their Outlook or Outlook Express inbox.

• Industrial-Strength Detection brings sophisticated, enterprise-class spam detection methods to individual users, without requiring expert knowledge.

• Ease-of-Use features include automatically updated blocked lists and a personal filter that learns preferences based on user behavior. The Automatic Setup feature saves time by scanning a user’s inbox at installation to learn preferences.
