February 13, 2006

OAKBROOK TERRACE, Ill. and BRUSSELS, BELGIUM-- February 13, 2006 -- VASCO Data Security International, Inc. (Nasdaq: VDSI), the global number one vendor of strong user authentication and e-signature products, and Imprivata, Inc., the enterprise single sign-on (ESSO) appliance company, today announced a strategic alliance to deliver a fully integrated, strong authentication solution for network logon and Windows access. The combined VASCO Digipass and Imprivata OneSign Network Logon solution, allows companies to take advantage of VASCO’s Digipass and VACMAN Controller, the leading strong authentication technology, fully integrated and packaged with Imprivata OneSign’s breakthrough appliance technology to deliver a highly-secure, easy to use and affordable network access solution with a single point of token management and deployment.

Companies faced with stringent security regulations including the US Homeland Security Policy Directive 12 (HSPD-12) are under pressure to not only secure remote access for users, but also implement secure access at the desktop. The combined solution eliminates the user’s reliance on the Windows password login, a known security vulnerability and “weak link” access point into the network. With Imprivata OneSign’s core access and security functionality and unique packaging, companies can now easily add Digipass token-based strong authentication to their networks. And because OneSign already integrates with a wide range of complimentary strong authentication options, organizations can also combine modalities to quickly and affordably implement additional effective two-factor authentication solutions.

VASCO’s Digipass enables users to generate one-time passwords, host authentication and e-signatures that safeguard access to e-business applications, corporate networks, and allow for more secure transactions. By using Digipass patented technology, IT can eliminate the weakest link in any security infrastructure: The use of static passwords that are easily stolen, guessed, reused, or shared.

“The partnership with Imprivata proves once more that VASCO’s VACMAN Controller enjoys high market esteem all over the world.” said Jan Valcke, President & COO VASCO. “Our focus is on improving the customer’s experience and success with their network security systems. We see the VASCO Digipass and Imprivata OneSign appliance as an innovative and breakthrough approach that goes well beyond current offerings for this market in order to save customers significant time and money.”

Imprivata OneSign is a proven enterprise SSO appliance that provides an easy, intelligent and affordable solution for organizations that need to quickly and effectively solve password management and user access issues. The Digipass/OneSign Network Logon solution takes advantage of OneSign’s out-of-the-box architecture and functionality to provide two factor authentication with no need for an additional, separate server, nor the need for a long installation engagement. The solution can be easily and seamlessly upgraded to include full support for enterprise SSO via a simple license key.

Summary of key benefits include:
- A completely integrated, highly secure and ease to deploy and maintain redundant appliance-based solution
- Out-of-the-box support for all Digipass tokens
- Secure on-line and off-line authentication
- Ability to centrally manage and administer authentication and access policies for all users, authentication modalities and applications
- Ability to seamlessly add complete ESSO capability via a license key

“In a short period of time we’ve been able to make a big impact on the market with OneSign – addressing password management and access control, given constrained IT staffs and the need for greater user productivity,” said Omar Hussain, president and CEO, Imprivata. “Our relationship with VASCO takes our commitment to providing cost effective and easy to implement access solutions even further.”

Imprivata will sell this complete solution through its worldwide channel beginning in April. For further information, please visit the company’s website at: http://www.imprivata.com or contact Imprivata sales at [email protected].
