OPEN DOOR NETWORKS SHIPS DOORSTOP PERSONAL FIREWALL 1.1

SAN FRANCISCO, CA. -- January 4, 2000 -- In concert with the MacWorld trade
show, Open Door Networks Inc. today announced that it was shipping version
1.1 of its DoorStop Firewall, Personal Edition. DoorStop Personal is an
easy to use, end-user version of Open Door's powerful server firewall
software, specifically focused on protecting Mac OS 9's new Internet
services. Version 1.1 adds a much-requested notification feature along with
other improvements, and is on display in Open Door's booth, number 3458.

DoorStop Personal Edition, which runs on Macs back to Mac OS 8.1, is an
important security enhancement for any Mac that is connected to the
Internet for long periods of time, for instance through a cable or DSL
modem or an intranet. DoorStop was originally developed by Open Door 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, and makes protecting Mac OS TCP/IP services as simple
as clicking on the services' icons. DoorStop 1.1 new features include:
User notification on specific connections being denied and/or
allowed by DoorStop
Ability to grow the DoorStop Admin window to show more services
Customized icons for additional services
Minor bug fixes

The 1.1 upgrade is free to all registered DoorStop Personal users, and
available from http://www.opendoor.com/doorstop/ . DoorStop Personal
Edition pricing ranges from $59 ($49 educational) for single licenses, up
through $1299 ($999 educational) for 50 user licenses. DoorStop Personal
can also be purchased with ShareWay IP 3.0 Personal Edition for $99 ($89
educational) or with a ShareWay IP 3.0 upgrade for $79 ($69 educational).
Additional volume and site licenses are also available.
