The corporate world is finally getting serious about the security of its information, according to an International Data Corporation (IDC) study. As Graph 3 shows, the research company forecasts that revenues for information security services will triple by 2005, topping the $21 billion mark. The increase represents a compound annual growth rate of more than 25 percent.

"The growing corporate appetite for remote LAN, Internet, extranet/intranet, and wireless access services will drive the need for advanced information security services," said Allan Carey, IDC senior analyst. In addition, new technologies to penetrate corporate networks seem to be developed almost as fast as new technologies to protect them. Consequently, many companies might turn to third-party providers for information security services to ensure that they always have best-of-breed applications guarding their most valuable corporate assets.
