OPEN DOOR NETWORKS SHIPS THE "WHO'S THERE?" FIREWALL ADVISOR

ASHLAND, OR. -- January 15, 2001 -- Open Door Networks Inc. today shipped its new "Who's There?" Firewall Advisor. Available immediately, "Who's There?" Firewall Advisor provides the next step in Internet security by helping users analyze and investigate access attempts to their Macintosh. With "Who's There?" Firewall Advisor users can determine the level of risk of an "attack" detected by their personal firewall, find the name, email address and phone number of an administrator associated with the attacker's network, and even automatically draft an email to that administrator.

With the ever-growing number of computers connected to the Internet through "always on" connections, there has been a significant increase in the number of hackers attempting to infiltrate those computers. Personal firewalls have been developed to thwart those attempts. As the number of attempts has risen, however, users have become increasingly confused as to the degree to which they should be concerned and what they can do in response. "Who's There?" Firewall Advisor works with the user's firewall to answer those questions.

"Open Door pioneered the Macintosh firewall market with our DoorStop product line," said Alan Oppenheimer, president of Open Door Networks. "But, as access attempts continue to increase, our customers need even more information than provided by their firewall's logging capabilities. We think 'Who's There?' Firewall Advisor will provide them with what they need to really understand what they should and should not be worried about, and to take action as needed."

"Who's There?" Firewall Advisor works with Open Door's DoorStop Personal and Server Editions and with Symantec's recently announced Norton Personal Firewall, which is based on technology licensed from Open Door. Features of "Who's There?" include:

"Who's There?" Firewall Advisor is priced at $39 for a single license, with volume and educational discounts available, and can be purchased directly from Open Door's Web site. Additional information on "Who's There?" along with a free evaluation version of the product is available off the "Who's There?" Web site at http://www.opendoor.com/whosthere/.
