VeriSign(R) Mobile Banking Solution to Include 2-Way Customer Interaction Platform From ClairMail

MOUNTAIN VIEW, CA and NOVATO, CA (Marketwire) - VeriSign, Inc. (NASDAQ: VRSN), the leading provider of digital infrastructure for the networked world, and ClairMail, Inc., the leader in 2-way mobile phone-based customer interaction, today announced that VeriSign will integrate ClairMail's secure 2-way mobile customer interaction platform and applications with the VeriSign® Mobile Banking Solution. The integration agreement is part of a global technology solution alliance between the two companies.

The agreement reflects VeriSign's strategy to meet the changing needs of financial institutions by leveraging its global infrastructure for mobile messaging and content delivery. ClairMail's scalable platform and breakthrough technology combined with VeriSign's messaging and operations infrastructure will facilitate bringing this revolutionary solution to market rapidly, benefiting financial institutions of all sizes.

"VeriSign is the leader in trusted managed services for ecommerce, security and financial services customers. We are confident that their world class messaging and operations infrastructure will enable banks, credit card issuers and brokerage customers to accelerate the use of the mobile device as a channel for 2-way customer interaction," said Joseph Salesky, CEO of ClairMail. "This partnership enables a broad feature set for mobile banking to be delivered to a wide set of financial institutions in an on-demand, trusted managed service."

Incorporating ClairMail's platform and applications enables the VeriSign Mobile Banking Solution to support the "triple play" of mobile interface types: messaging (SMS and email), mobile web and native client applications. Support of these interface types enables financial institutions to offer reliable, secure and easy-to-use mobile services to their customers on a wide range of handsets. The joint solution securely and cost-effectively integrates with a financial institution's systems of record and enables a broad set of 2-way services on one platform with a single implementation, including account management, fraud mitigation, actionable alerts, mobile payments, marketing campaigns and no-hold customer service.

"Since launching the VeriSign Mobile Banking Solution in March, we've sought differentiated offerings that dovetail with our solution strategy by creating a true competitive advantage for financial institutions," said Brian Matthews, vice president, enterprise solutions, VeriSign. "We chose to work with ClairMail because their approach met VeriSign's stringent requirements for scalability, reliability and security. Together, we can enable financial institutions to develop cost-saving efficiencies, while helping them build loyal, lasting relationships with their customers."

"Simple user experience, security, flexible architecture and broad device support are critical components for an effective mobile banking and payments solution," said Bob Egan, chief analyst & research area director, TowerGroup. "Mobility drives digital/electronic commerce services to the absolute domain of the individual, 24x7, right here, right now. Banks who demonstrate market leadership will deploy secure, real-time multi-modal solutions."
