Digital Insight and TriCipher Partner to Enhance Online Banking Security With Multifactor Authentication

Partnership Will Provide Middle Market Financial Institutions With
Customizable Solution That Helps Protect End Users and Administrators
Against Online Fraud and Identity Theft

CALABASAS, Calif., Aug. 25 /PRNewswire-FirstCall/ -- Digital Insight Corp.
(Nasdaq: DGIN) (http://www.digitalinsight.com), the leading online banking provider,
announced today it has entered into a strategic partnership with TriCipher,
Inc. (http://www.tricipher.com), a leading innovator of strong authentication
technologies, to help enhance online banking security. The latest partnership
supporting Digital Insight's comprehensive security offerings, Multifactor
Authentication is designed to help banks and credit unions seamlessly protect
their users and administrators from various forms of online fraud by
strengthening security at login with a multi-part credential for each user.
"Digital Insight is committed to helping ensure the security of online
banking for our clients and their users in a convenient manner, and strong
authentication has emerged as one of the most important steps in protecting
against Internet-based electronic fraud," said Scott Mackelprang, vice
president of security and compliance for Digital Insight. "The Multifactor
Authentication solution we have chosen can significantly reduce the threat of
current online concerns such as phishing, pharming and other unauthorized user
attacks, while still providing scalability to address the potential security
concerns of tomorrow."
Multifactor Authentication from Digital Insight meets the diverse needs of
the Digital Insight client base. Client financial institutions can implement
a customizable, user-friendly version of TriCipher's robust strong
authentication system and still maintain enough flexibility to create
different authentication levels that match application, data or user risk.
The baseline solution enhances login security beyond username and password by
storing a second factor of identity authentication on each user's PC that
helps prevent fraudsters from impersonating legitimate users. Depending on
the level of security desired, a financial institution can elect to
incorporate additional layers of strong authentication from users in the form
of challenge questions and temporary passcodes, downloaded software modules,
USB memory tokens, or other methods of identity verification.
"Flexibility and cost have long been critical issues for middle market
financial institutions seeking the security of strong authentication without
significant change to existing infrastructure," added TriCipher CEO Ravi
Ganesan, who formerly served as Vice Chairman of CheckFree Corporation. "We
have worked with Digital Insight to develop a customizable solution that meets
the specific needs of their customers and believe this partnership will
provide significant, user-friendly protection to their clients and end users."
"Digital Insight continues to provide the critical capabilities, solutions
and security services our client financial institutions need to compete and
win in the marketplace," said Digital Insight Chairman, President and CEO Jeff
Stiefler. "We are pleased to partner with a leading anti-fraud technology
provider like TriCipher and look forward to working with them to help our
clients deliver greater peace of mind to users."
