Vasco Data Security, a software security company specializing in authentication products, has been rank 5th in Fortune Small Business’ Top 100 list of America’s fastest-growing small public companies.

For the compilation of the eighth annual list, Fortune Small Business worked with financial research firm Zacks, which ranked public companies with revenues of less than $200 million and a stock price of more than $1. All companies that met these criteria were ranked, 1-100, based on the past three years’ earnings growth, revenue growth, and stock performance. The overall rank was based on the sum of these three ranks. Banks and real-estate firms were excluded from the list.

Vasco ranks 5th- as to eleventh in 2007 – and is the first technology and IT-company in Fortune Small Business’ Top 100 list. “We see this great accomplishment as recognition for Vasco’s sustained business success”, said Jan Valcke, Vasco’s President & COO. “This ranking illustrates Vasco’s leading presence as a global market leader in strong authentication.”

Currently, Vasco secures approximately 7,100 companies, including over 1,000 banks, against e-fraud in more than 100 countries.
