January 31, 2007

NEW YORK, NY — January 31, 2006 -- VASCO Data Security International, Inc. (www.vasco.com) (Nasdaq: VDSI), the global number one vendor of strong user authentication and e-signature products, today announced at its 3rd Investor and Media Summit in New York that it has passed the landmark of 150 customers in the U.S. banking sector.

The company reaps the benefits of the momentum created by FFIEC guidelines regarding high-risk money transactions and the continuing threat of online fraud schemes such as phishing, man-in-the-middle attacks and Trojan Horses.
VASCO’s strong user authentication and e-signature technology is the perfect tool to counter the above mentioned threats in a simple yet highly effective way.

According to VASCO, the combination of its continuing reinforcement of its U.S. sales staff and its solution partnerships with companies such as Fiserv and Fundtech, are the main reason for its countrywide success.

During the Investor and Media Summit, Mr. Ken Hunt, VASCO’s Chairman and CEO, announced that VASCO doubled its U.S. sales force during the last 12 months.
“VASCO proves once again to be the strong authentication market leader in the U.S. and worldwide,” concluded Mr. Hunt. “We are convinced that we will be able to reinforce our leadership position.”
