CALYPTIX SECURITY RELEASES ACCESSENFORCER SOFTWARE VERSION 1.5

April 15, 2007 — CHARLOTTE, NC Internet security firm, Calyptix Security, has released AccessEnforcer version 1.5, the newest and most robust version of the all-in-one network security software imbedded in its AccessEnforcer™ series appliances.

AccessEnforcer version 1.5 makes significant enhancements in the area of email management by providing an email quarantine for POP3 and SMTP users. Built on a customized version of SpamAssasin, the industry's leading open- source spam blocking filter, the AccessEnforcer spam filter examines each piece of incoming mail and segments suspicious mail to a user-specific quarantine box. According to administrator configuration, an email will periodically be sent to active users on the network with a summary of suspicious activity. A user can then link to his/her quarantine to examine the message and see a harmless preview of its contents. Unwanted messages can be "trashed" for good, or, if the mail is benign, it can be released and sent to the user's inbox.
