"Omgeo chose Securant's ClearTrust authorization solution to enable role-based control of its Intelligent Trade Management Solutions(SM), including the settlement portal," said George Wrenn, director of portal development of Omgeo, a global joint venture of the Depository Trust & Clearing Corporation (DTCC) and Thomson Financial. "The acquisition should prove to be beneficial for Omgeo and other industry participants as RSA Security will be able to produce additional powerful solutions for the industry." 2 "Authorization has always been part of RSA Security's mission to enable secure e-business by ensuring the authenticity of people, devices and transactions," said Art Coviello, CEO and president at RSA Security. "This acquisition will help us fulfill that mission. We started with RSA SecurID authentication solutions to help organizations ensure the identity of users. We are adding the ClearTrust authorization solution to enable organizations to control what those users see or do once they have been authenticated. RSA BSAFE encryption software is designed to ensure the privacy and integrity of information and our RSA Keon PKI solutions are designed to ensure the integrity of the transactions users have been authorized to conduct." "Authorization is an important part of enabling e-commerce, and a natural complement to RSA Security's current capabilities," said Charles Kolodgy, research manager at IDC. "Securant is a technology leader in this segment, and RSA Security's acquisition should enable the company to offer even stronger authorization solutions. This move should add a healthy dose of competition to the market, which can help the segment grow and expand technology innovation." "RSA Security's acquisition of Securant is a very positive step for the company," said Dr. Verena Salzmann, consultant at research firm DataMonitor. "Adding an authorization solution is an organic move that extends the company's product range." NEW PRODUCT TO SERVE EXPANDING MARKET RSA Security believes this acquisition will enable it to provide leadership in the growing authorization market segment. According to the research firm IDC, the Web-based authorization market segment is expected to grow at a compound annual rate of nearly 70 percent over the next four years. This increase is being driven by organizations that need to both expand the number and types of users who can access their networks, applications and Web sites, and at the same time, consolidate their numerous Web sites under a comprehensive portal management system. Acquiring Securant enables the company to offer an award-winning authorization product that is also a natural complement to RSA Security's authentication, PKI and encryption solutions. Securant's ClearTrust was recently named the best product in the authorization market segment, winning both Network Computing's Editor's Choice and NetworkWorld's Blue Ribbon awards. These tests included competitors such as Entrust, Oblix, Netegrity, Open-Networks, Entegrity, Baltimore and Symantec. Compared with other authorization solutions, ClearTrust has been recognized for the following primary business benefits: - Total solution scalability - Speed of deployment - Intuitive and cost-effective user management, and - Open, interoperable Java-based architecture with full LDAP integration ABOUT RSA SECURITY INC.
