OPEN DOOR NETWORKS ANNOUNCES THE DOORSTOP X SECURITY SUITE

A new, comprehensive approach to Macintosh Internet security

ASHLAND, OR. -- December 12, 2005 -- Open Door Networks Inc. today announced an expanded line of Internet security products, the centerpiece of which is its new DoorStop X Security Suite. Available immediately, the DoorStop X Security Suite represents a comprehensive, integrated approach to protecting Macs on the Internet. The Suite consists of major new releases of Open Door's DoorStop X Firewall and Who's There? Firewall Advisor, along with an electronic second edition of the book "Internet Security for Your Macintosh: A Guide for the Rest of Us" (see "Open Door Networks revs security product line" for individual product details). The three revised products are designed to act together in the Suite, providing users with both the tools and the information they need to better protect their Macs on the Internet.

In a typical Suite scenario, an access attempt from the Internet to a particular service on a Mac protected by the DoorStop X Firewall is blocked and logged by that firewall. The log entry and associated information (including risk factor) are immediately flagged and highlighted by Who's There? in an intuitive, easy-to-understand format. The user can then delve more deeply into details of the accessed service by viewing relevant sections in "Internet Security for Your Macintosh." The user can also invoke DoorStop X directly to change the protection to that service as needed. Finally the user can browse through the book to learn more, either from DoorStop X or Who's There? or using the included standalone PDF version.

Through the DoorStop X Security Suite and scenarios like this one, not only do users better protect their machines, but they also better understand the issues associated with that protection.

Key integration aspects among the three Suite products include:

"Our approach with the DoorStop X Security Suite is to help users help themselves by providing them with the background information they need to secure their systems, integrated directly into key tools for securing those systems," said Alan Oppenheimer, president and founder of Open Door Networks.

The DoorStop X Security Suite includes DoorStop X Firewall 1.1, Who's There? Firewall Advisor 2.0 and both standalone and integrated copies of "Internet Security for Your Macintosh: A Guide for the Rest of Us," second edition. The Suite is available for purchase directly off Open Door's Web site (www.opendoor.com) for a special introductory price of $69 through January 31, 2006. Upgrades to the full Suite for DoorStop X Firewall and Who's There? users are also available, as are free evaluation versions of DoorStop X and Who's There?, along with a sample chapter from "Internet Security for Your Macintosh."
