With VASCO’s entire family of Digipass products already integrated into the complete Identikey product line, organizations can choose a turnkey web portal security solution including Digipass strong two-factor authentication and e-signature capabilities, at an affordable purchase price and low total cost of ownership.

The Identikey software offers VASCO a web authorization product that extends security beyond the LAN authentication market of SnareWorks SecureServer, providing quick-to-implement web portal security. Organizations looking for full enterprise-wide security with multiplatform support as well as capabilities for providing true Single Sign-On and PKI enablement can draw on VASCO’s SnareWorks enterprise security software. VASCO will market and sell the Identikey product family under its SnareWorks brand, merging the companies’ sales and development operations worldwide. Mark Kefford, Identikey’s founder and president, will also join VASCO’s management team.

Mark Kefford of Identikey concurred. “We developed our entire product family specifically to address web portal security as the fastest-growing segment of the security market. Over the past several years, our efforts have been focused on developing software products that are affordable, easy to implement, and simple to manage – eliminating the cost and integration
complexity which present high barriers to entry for organizations wishing to secure their web portals. We’re pleased that VASCO has recognized our security software’s strength in addressing this critical and largely untapped market.”
