MARKET AN ALYSIS Worldwide Security Software Forecast, 2003–2007
Christian A. Christiansen Charles J. Kolodgy Brian E. Burke Sally Hudson


In light of current economic and industry trends, IDC has updated the forecast for security software revenue for 2002–2006. IDC now expects the worldwide revenue for security software to be $6.9 billion in 2002, an increase of 16.2% from 2001. The market is now forecast to increase to $14.4 billion in 2007, a 16% compound annual growth rate (CAGR) for the period from 2002 through 2007. Highlights are as follows: ! 3A vendors are quickly repositioning themselves as identity management vendors. IDC believes single sign-on (SSO), provisioning, authentication, legacy access management, PKI, security management, and directory services will all be critical components of identity management. Web services represent a whole new model for integrating applications, which means organizations will have to think in a whole new way about security. IDC believes identity management will be the foundation for Web services. ! 2002 proved to be an even more impressive year for the SCM market than IDC forecast in mid-2001. All of the major vendors in the SCM market performed extremely well in 2002. In addition, we believe that many SCM vendors are quietly but successfully increasing the subscription renewal rate with both corporations and consumers, thus generating a more predictable revenue stream. ! 2002 was a down year for the firewall/VPN software market. Although the overall market experienced negative growth, positive growth occurred in Western Europe and the Asia/Pacific region. IDC believes that the firewall/VPN hardware appliances are putting pressure on the enterprise software market. More software vendors are providing their software preinstalled in hardware appliances, which will continue to move the two markets together. ! 2002 provided another strong year for the intrusion detection and vulnerability assessment (ID&VA) market, and strong opportunities continue outside of North America. IDC believes that the intrusion detection market will become one that offers solutions that combine detection with prevention. Enterprises continue to use vulnerability assessment (VA) software to determine their security posture, which is a growing requirement of various government regulations and industry security best practices.
