PRESS RELEASE

OAKBROOK TERRACE, Illinois and ZURICH, Switzerland – September 11, 2012 - VASCO Data Security International, Inc. (Nasdaq: VDSI) (www.vasco.com), a leading software security company specializing in strong authentication products and services, announces today that Drupal (www.drupal.org) has added MYDIGIPASS.COM for DRUPAL v6 to its contributed modules enabling web developers to embed secure login access for the websites they build through the Drupal community.

Drupal is an open source content management platform powering millions of websites and applications. The Drupal platform is built, used, and supported by an active and diverse community of people around the world to build all sort of websites, from personal blogs to enterprise applications.

With the MYDIGIPASS.COM module for DRUPAL v6 the integration of two-factor authentication in websites that are built using the open source platform, becomes a matter of simple configuration instead of complicated development work. Web developers using Drupal v6 can add strong two-factor authentication in a straightforward and cost-efficient manner while at the same time providing their end-users with secure access to secluded content and online accounts in a most convenient way. Online profiles and user attributes can easily be managed on the MYDIGIPASS.COM authentication portal.

The solution offers an additional advantage: by becoming a part of the MYDIGIPASS.COM application eco-system, web site builders will also gain extra visibility that could potentially result in more website traffic. To integrate MYDIGIPASS into a Drupal v6 website, the website developer simply needs to select and install the module and request the MYDIGIPASS.COM connect button on developer.mydigipass.com. The plugin, which is freely available at http://drupal.org/project/mydigipass, contains necessary libraries, attributes and flows, enabling web developers to match the integration of MYDIGIPASS.COM in any Drupal v6 website through a simple configuration process.

“We are thrilled that MYDIGIPASS.COM is now available on Drupal’s open source platform”, says Jan Valcke, President and COO of VASCO Data Security. “The MYDIGIPASS.COM module for Drupal v6 enables Drupal’s users to add strong authentication to their websites assuring a secure login process and greatly enhancing security and user convenience.”
