Combining a proprietary panel of more than 50,000 senior IT buyers with our robust data-collection methodologies, 451 Research's Voice of the Enterprise: Information Security tracks and analyzes the disruption occurring in the market today and exposes the major opportunities for enterprises, IT vendors, suppliers and investors. The study represents more than 900 completes of a web-based survey, completed by information security decision-makers worldwide, primarily based in North America and Europe, and supplemented by 20 in-depth, phone-based interviews. The sample is representative of small, medium, large and very large organizations in both the private and public sectors. In addition to regular quarterly topics, the survey focuses vendor valuations of three information security toolsets used within enterprises: Security Information and Event Management, Endpoint Security and Application Security tools. This includes the 451 Research Vendor Window, which plots enterprise adoption as well as Promise and Fulfillment indices that compare vendors' effectiveness at both marketing and execution.
