OPEN DOOR NETWORKS SHIPS DOORSTOP

MACINTOSH-BASED FIREWALL ENHANCES SERVER SECURITY

ASHLAND, OR. -- September 9, 1998 -- Open Door Networks Inc. today announced that it had begun shipping a major new Mac OS security product. DoorStop (TM) is a software-based "firewall" product which lets server administrators specify client IP addresses that should be denied access to particular services. The product can also keep a log of all access attempts to the server. DoorStop enhances the security of Macintosh servers by providing additional levels of protection and logging, above and beyond those already built into the Mac OS and the servers themselves.

Unlike conventional, hardware-based firewalls, a copy of DoorStop is installed directly on the servers where its features are desired. By distributing the firewall functionality down to the particular servers being protected, DoorStop can provide additional levels of flexibility and a significantly simplified user interface, plus overall cost savings.

DoorStop 1.0 supports Macintosh servers which use TCP/IP protocols and is specifically targeted at Open Door's ShareWay IP product line, Apple's AppleShare IP and StarNine Technology's WebSTAR. "The combination of DoorStop, WebSTAR 3.0 and the Mac OS work to provide an Internet solution that is highly functional, incredibly easy to use and very, very secure," said Eric Zelenka, product manager for WebSTAR. "Security is something that can never be taken too seriously, and, with DoorStop, server administrators have a very powerful new security option."

DoorStop is especially useful when run with ShareWay IP. ShareWay IP enables previously AppleTalk-only AFP (AppleTalk Filing Protocol) servers to communicate over the Internet or an intranet. This increasingly essential capability greatly expands the reach of AFP servers such as the Mac's built-in personal file sharing. It also, however, exposes those servers, for the first time, to access from beyond an organization's AppleTalk network, requiring the additional security provided by DoorStop.

DoorStop features include:

DoorStop requires a PowerPC processor, Mac OS 8.1 and Open Transport 1.3 or later. A free evaluation version is available off the DoorStop Web site at http://www.opendoor.com/doorstop/ along with additional information on the product. The retail price for a single copy of DoorStop is $299, with an educational price of $199. Through October 15, the product is available at the special introductory price of $199 ($149 educational). Volume and site licenses are also available.
