Definition
IBM QRadar is a security information and event management (SIEM) platform that collects and correlates log and network flow data across an organization to detect threats, prioritize alerts, and support security investigations.
Overview
IBM QRadar aggregates log events and network flow data from across an organization's infrastructure — firewalls, servers, endpoints, and applications — into a centralized platform, applying correlation rules to reduce large volumes of raw events into a smaller number of prioritized offenses that analysts can investigate. This offense-based model is one of QRadar's distinguishing characteristics compared to some other Security Information and Event Management (SIEM) platforms. QRadar's analytics engine incorporates behavioral analysis and threat intelligence feeds to help identify anomalies that might indicate a compromise, and it integrates with IBM's broader security portfolio, including QRadar SOAR for automated incident response playbooks. IBM has also incorporated AI-assisted investigation capabilities to help analysts triage and understand offenses faster. As an enterprise-grade SIEM, QRadar competes with platforms like Splunk SIEM and Microsoft Sentinel, and is commonly deployed by large organizations with mature security operations centers that need to correlate high volumes of log and network data.
