These capabilities allow QRadar to analyze vast amounts of data and accurately prioritize potential security events, separating real threats from explainable anomalies. For the second year in a row, IBM was positioned the furthest for both completeness of vision and the ability to execute. On the completeness of vision scale, Gartner analysts evaluated the ability of vendors to understand buyers' wants and needs, and to translate those into products and services. With regard to ability to execute, Gartner evaluated on seven criteria, including customer experience and market responsiveness. Earlier this year, IBM Security brought the power of QRadar SIEM to the cloud, launching new cloud-based software-as-a-service delivery models that combine advanced monitoring and analytics with the simplicity of a hosted deployment.
