IDC has sized the market for private and public cloud security products, and forecasted strong five-year growth for both segments. A new report published last week (Worldwide Cloud Security 2011-2015 Forecast) highlights private clouds as biggest opportunity for security products vendors to sell cloud-focused security hardware and software.
The public cloud segment, while much smaller, will grow rapidly over the next five years, as cloud providers weave security features and underlying functionality into their public infrastructure, platform and software as a service offerings.
Spending on security products for private cloud environments will be the dominant segment of the overall public/private cloud security market over the next five years. In 2010, nearly three-quarters of revenue from security products sold into cloud environments were classified as private cloud. The need for advanced identity, monitoring, policy, data protection, and management tools to control these new, highly automated, virtualised on-demand enterprise datacentres.
Security products sold into public cloud environments will be the fastest-growing segment of the cloud security market, at a 36% compound annual growth rate over the next five years. While spending on security products for public clouds accounted for only one-quarter of overall cloud security revenue in 2010, this segment will represent nearly one-third of the market by 2015.
IDC expects CSPs' consumption of security products to be driven by increased demand by enterprises and consumers for more security features in cloud services overall, from social media and personal Web productivity tools (i.e., Facebook and Dropbox) to enterprise-class cloud platforms (such as Amazon Web Services and salesforce.com). As organisations adopt more cloud services and technology, they will expect the same level of security controls and safeguards integrated into the technology as they have with their own internal ID deployments.
Overall, the combined private/public cloud security market will account for nearly 14% of all security products sold worldwide by 2015. (Cloud security products accounted for only 5.7% of the total market in 2010).
