Group Logic Releases MassTransit 5.1

New Features Further Empower Users and IT to Capture Strategic Business
Value through Enterprise File Transfer

September 10, 2007 ( Arlington , VA) - Group Logic, the leading provider of
enterprise file transfer and Mac/Windows connectivity solutions today
announced the immediate availability of MassTransit 5.1. The new version
includes nearly two-dozen new features designed to empower users through
improved ease-of-use, visibility and automation. It also delivers the first
phase of integration with enterprise security architectures through support
for Active Directory. The complete 5.1 feature set reinforces MassTransit's
unique position as the only enterprise software solution proven to
transform digital file transfers into strategic business processes.

MassTransit 5.1 makes it even easier for untrained users to successfully
send large folders. Support for Active Directory-based passwords and Single
Sign On (SSO) enable users to quickly and easily access the product's web
browser-based file transfer client. Version 5.1's comprehensive Web Client
compatibility - including support for Intel Macs, Vista, Internet Explorer
7 and Firefox 2.0 - insures users can benefit from MassTransit regardless
of browser or operating system.

Version 5.1 extends the product's unique notification, logging and tracking
features by providing notification through SMS text messages - allowing any
user with a cell phone to be instantly informed of key file transfer
events. MassTransit also extends access to its web-based log allowing any
Active Directory-based user to access and search file transfer histories.
With this enhancement, timely file delivery information is more easily
available to everyone who needs it to ensure business objectives are met.

Version 5.1 also enhances MassTransit's workflow automation and integration
tools. New Actions are provided for automatically moving files in transit,
which increases customers' ability to eliminate manual work. Other new
Actions allow for scripts to be triggered from virtually any language,
further providing for custom automation and insuring that file transfer
workflows can handle the most demanding volumes without negatively
impacting users productivity.

"To gain strategic value from digital file transfer business processes,
enterprises must enable users to quickly, easily and automatically move
files wherever they need to go - and to tightly monitor and manage the
delivery process to ensure the job gets done. " said Andy Lewis , Senior
Vice President of Sales, Group Logic. "MassTransit is the most powerful
solution for getting this done at an enterprise level - and the new release
reinforces this by improving all the features that empower users to use
digital file transfer business processes for their organization's benefit."

The product's integration with Active Directory is a highlight of the new
release that builds on MassTransit's unique, enterprise capabilities. The
MassTransit product roadmap includes tight integration with the technology
and Version 5.1 delivers the roadmap's first phase, allowing MassTransit
accounts to be linked to Active Directory for password and account
management.

"Securing customer's data in transit is absolutely critical in today's
business environment," said Lewis, "MassTransit 5.1's integration with
Active Directory offers increased security to customers exchanging files on
the Internet and it allows enterprises to gain more from their investments
in Active Directory-based architectures when deploying MassTransit. As the
first step in our Active Directory integration plan, the feature highlights
our commitment to solutions that deliver strategic value at the enterprise
level."

MassTransit 5.1 is available immediately and is a free update available to
all licensed MassTransit 5.0 users that have an active support contract.
