news_VASCO and OpSource partner to provide secure cloud services

OAKBROOK TERRACE, Illinois and ZURICH, Switzerland – October 5th, 2011 - VASCO Data Security International, Inc. (Nasdaq: VDSI) (www.vasco.com), a leading software security company specializing in authentication products, announces today that it has partnered with OpSource, Inc., Dimension Data’s wholly-owned enterprise cloud and managed hosting business, providing an enterprise-class solution for joint clients. VASCO’s authentication platforms VACMAN®, IDENTIKEY® and its cloud-based authentication DIGIPASS as a Service® offering are now available for the OpSource Cloud.

OpSource provides enterprise cloud and managed hosting solutions, enabling businesses of all sizes to accelerate growth and scale operations while controlling costs and reducing IT infrastructure support risks. As part of the partnership, VASCO’s strong authentication and e-signature solutions have been tested and validated on the OpSource Cloud. VASCO adds additional security to OpSource’s Cloud platform, offering businesses cloud and managed hosting solutions that are secure, high performance and easy to manage.

The joint partnership provides enterprises with customized and secure cloud-based services that match the organization’s business needs in addition to their application hosting requirements.
VASCO’s two-factor authentication technology replaces less secure static passwords with dynamic one-time passwords. This enhancement increases access security without compromising user convenience, assuring clients that only properly authenticated users gain access to the OpSource network.

“We have seen dramatic increases in the demand for public cloud hosting, however, many organizations are still hesitant to trust business-critical information to the cloud,” says Jon Beck, SVP of World Channels and Alliances at OpSource. “Through this partnership with VASCO, we deliver joint clients a high-performance cloud solution with convenient and secure authentication and login.”

“VASCO has a longstanding experience in providing security solutions for businesses prone to identity and data fraud. With its authentication platforms and DIGIPASS as a Service offering, VASCO provides an additional security layer for cloud application providers mitigating risk of fraud and data theft and boosting end-user confidence”, says T. Kendall Hunt, founder, chairman and CEO of VASCO Data Security. “With the combination of VASCO’s authentication solutions and OpSource's cloud application platform, we will together provide enterprises with a more comprehensive and secure cloud infrastructure."
