IBM QRadar

Long-established enterprise SIEM offering log correlation, UEBA and SOAR, now offered as SaaS or on-premises appliances.

Visit IBM QRadar Alternatives

IBM QRadar is a longstanding enterprise SIEM providing log collection, real-time correlation rules, network flow analysis, and user/entity behavior analytics, historically deployed as dedicated hardware/virtual appliances and increasingly offered as QRadar SIEM SaaS on IBM Cloud. IBM has been consolidating its security portfolio around QRadar plus its acquired SOAR (formerly Resilient) and EDR capabilities to cover detection through response in one suite. It suits large enterprises and MSSPs with established SOC processes already built around QRadar's rule and offense model, though newer cloud-native SIEMs have made inroads on ease of onboarding. Pricing is quote-based and not published; it typically scales with events-per-second (EPS) or flows ingested.

SOAR (security orchestration, automation and response) A platform that automates and orchestrates the response steps a security team takes after an alert is raised. Threat intelligence Analyzed information about attacker groups, tools, and techniques used to anticipate and defend against threats, not just react to them. User and entity behavior analytics (UEBA) Analytics that baseline normal user and device behavior and flag deviations that could signal a compromise, even without a known IOC.
