As per the survey, the vast majority of respondents expected their security budgets to increase or stay the same -- 45 percent and 50 percent respectively -- with only 5 percent expecting their budget to decrease in 2012, Gartner reported.

While this was the general overall pattern, respondents in some emerging regions were more likely to expect an increase in their budgets.

"Although security remains fairly resilient in tough times, the prolonged financial crises seen in the U.S. and Europe have had some impact on IT security spending globally but to a lesser extent for emerging countries, such as Brazil, China and India," said Ruggero Contu, research director at Gartner.

"In 2012, the market contributing most to overall growth, excluding exchange rate effects, is security services, followed by security software," Pingree said.

This increased demand for security products and services will be driven by the need for organizations to mitigate risks and reduce security vulnerabilities in the face of the continuous and evolving sophistication of threats.
