PRESS RELEASE

FREMONT, Calif., April 2, 2009 -- ActivIdentity Corporation (NASDAQ: ACTI), a global leader in strong authentication and credential management, today announced the release of 4TRESS 4.0 Authentication Server, the market leading solution for open, standards based strong authentication. Organizations are challenged to create greater efficiencies while leveraging existing resources and managing costs. Building on its market leading reputation as a feature-rich and highly flexible authentication solution, 4TRESS 4.0 expands operating system support and OATH authentication options for even greater flexibility.

"We are committed to open standards and an array of deployment options in 4TRESS," said Jerome Becquart, vice president product and services. "This release delivers even greater value to our customers, allowing them to address heterogeneous IT environments and varied authentication needs across their organizations."

The new release fully supports ActivIdentity's recently announced family of Soft Tokens. 4TRESS has a simple and secure process to activate soft tokens on the devices that users already carry, thereby dramatically altering the trade-off between security and convenience that has traditionally restricted user acceptance.

4TRESS meets many of the challenges faced by organizations in today's rapidly changing business environment, delivering an authentication infrastructure that supports multiple service channels, business units and transaction risk levels with a single solution.

The ActivIdentity 4TRESS Authentication Server 4.0 is available today. More information can be found at http://www.actividentity.com/products/4tress__home.php and at http://www.actividentity.com/products/tokens_soft__home.php.
