MassTransit Gains Improved Encryption and Security Capabilities

Group Logic Simplifies Creation of Secure Digital Printing Workflows

Arlington, VA -- April 3, 2002 -- Group Logic, developer of best-selling
network workflow software products, announced the planned availability of
significant new security capabilities within its MassTransit Enterprise
product. With the new capabilities organizations can, for the first time,
build secure digital workflows across multiple organizations with
Industry-standard encryption and authentication technology. MassTransit
acts as a "digital shipping and receiving department" that completely
automates and manages the process of transferring graphics, multimedia, and
other production files between print media suppliers and their customers.

MassTransit Enterprise version 4.1 delivers three key security-enhancing
capabilities:

- Protection of digital data in transit through the use of OpenSSL-based
encryption. MassTransit Enterprise will use an RC4-based encryption
algorithm with a 128-bit key for encryption of data transfers between web
clients and servers, as well as server-to-server transfers.

- Validation of identity of both web clients and servers with support for
X.509 digital certificates.

- Improved network security by eliminating the requirement that
organizations open a dedicated firewall port for MassTransit traffic.
Instead, MassTransit will now use TCP/IP port 443, the well-known port used
for SSL connections carrying data.

MassTransit Enterprise v.4.1 will also add support for web browser clients
operating in the Macintosh OS X operating system.

"We've worked closely with our customers to respond to their growing
requirements for a higher level of security in their workflows" said Andy
Lewis, Vice President of Marketing and Sales at Group Logic. "In the past,"
Lewis explained, "customers would have to implement a virtual private
network to provide this type of security, a process that can add complexity
to a workflow." With these new capabilities, Lewis claims, "Our customers
will be able to implement secure workflows with the same simplicity and
ease of use they've come to expect and enjoy from other MassTransit
capabilities."

Pricing and Availability
Version 4.1 of MassTransit Enterprise is scheduled for general availability
by the end of the Second Quarter of 2002. The update will be provided free
of charge to existing MassTransit Enterprise v.4.0 customers with
maintenance and support agreements.
