OPEN DOOR NETWORKS ENHANCES MAC OS 9 WITH NEW PRODUCTS

SHAREWAY IP 3.0 AND DOORSTOP PERSONAL EDITION AUGMENT SECURITY OF ALL
INTERNET-CONNECTED MACS

ASHLAND, OR. -- October 25, 1999 -- Open Door Networks Inc., the developer
of Mac OS 9's Internet file sharing feature, today announced major
additions to its line of Macintosh Internet products, enhancing the
security of Mac OS 9's Internet features, and of Internet-connected Macs in
general. ShareWay IP 3.0, a major upgrade to Internet file sharing, is
shipping immediately, and DoorStop Personal Edition, an end-user version of
Open Door's powerful server firewall software, is available in a public
beta release

Open Door's product announcements were made in concert with Mac OS 9's
retail availability, enabling Mac OS 9 users to enhance their system's
security from day one. "DoorStop Personal Edition, in combination with
ShareWay IP and Mac OS 9, represent a superb mix of Internet power,
Macintosh ease of use and absolutely essential security," said Gavin Eadie,
Director of Strategic Technologies at the University of Michigan. "We're
really excited about what Open Door and Apple have been doing in these
critical areas." Michigan's network includes over 6000 Macs.

"Open Door is proud to have helped Mac OS 9 raise the bar as far as
built-in Internet features," said Alan Oppenheimer, president of Open Door
Networks. "Users are rightly wondering, however, whether such increased
features bring increased security risks. With our new products, we directly
address these concerns. Mac OS 9 users can upgrade the version of ShareWay
included with their system to ShareWay 3.0's new security features, and can
also install DoorStop Personal Edition to protect all their Internet
services. Other Internet-connected Macs users, such as those using cable or
DSL modems, can also take advantage of these inexpensive, easy-to-use
products as well."

PRODUCT FEATURES

ShareWay IP 3.0, available immediately off Open Door's Web site at
http://www.opendoor.com/shareway/, is a major upgrade to the technology
chosen by Apple to implement Mac OS 9's Internet file sharing (see "Open
Door's ShareWay IP Technology included in Mac OS 9"). ShareWay IP 3.0
requires Mac OS 7.5.5 or later, and works with 68K as well as PowerPC Macs.
New features include:

- Ability to allow or deny IP access for guests, and for specific user names
- Display of IP-connected users' names and IP addresses

DoorStop Personal Edition, available as a public beta release from

DoorStop firewall software. DoorStop was originally developed for use on
servers such as AppleShare IP and Open Door's ShareWay IP Professional.
DoorStop Personal Edition is a greatly simplified version of the server
product, making protecting Mac OS TCP/IP services as simple as clicking on
service icons. DoorStop Personal Edition requires a PowerPC Mac and Mac OS
8.1 or later. Its features include:

- Built-in support for Internet file sharing (through Mac OS 9's file
sharing and ShareWay IP)
- Built-in support for Mac OS 9's Program Linking over TCP/IP
- An advanced mode for protecting any TCP/IP service
- Logging of allowed and/or denied TCP/IP connections.
