OPEN DOOR NETWORKS ENHANCES LEOPARD INTERNET SECURITY

Upgraded products help users learn about and protect new Mac OS network features

ASHLAND, OR. -- November 5, 2007 -- Open Door Networks Inc. today announced updates to its comprehensive line of Macintosh Internet security products. The updates, available immediately, significantly enhance the security of the networking features that Apple has added in its just-shipped Leopard (Mac OS X 10.5) operating system. They also help users understand and react to new and evolving security threats.

"Leopard provides a host of new Internet-based services," said Alan Oppenheimer, president of Open Door Networks. "New features like Screen Sharing and Back to My Mac are incredibly powerful but also serious security risks. It's important that Mac users both understand these new features and their ramifications, and have the tools to fully secure them. That's where our products come in."

Each of Open Door's security products is being updated:

Free 30-day evaluation versions of the updated products are available from Open Door's Web site at http://www.opendoor.com. Upgrades for any product purchased this year are free. Mac OS X 10.3.9 or later is required, and 10.4.10 or later is recommended.

Access to Open Door's Internet security blog and Top 10 list, both integrated directly into the products, is also freely available to all at http://www.isfym.com and http://www.isfym.com/top10/.
