IBM QRadar SIEM

IBM QRadar SIEM is one of the most established enterprise security information and event management platforms in the world, originating from Q1 Labs (founded 2001, acquired by IBM in 2011) and built over 30+ years into a comprehensive threat detection platform trusted across financial services, government, defense, and critical infrastructure globally.

In September 2024, IBM sold its QRadar SaaS assets to Palo Alto Networks in a major strategic shift. QRadar Cloud, QRadar SOAR cloud, and QRadar Log Insights all reached end-of-life on April 14, 2026. QRadar EDR and XDR SaaS followed on August 31, 2026. However, IBM QRadar SIEM on-premises was explicitly excluded from the sale and remains fully supported by IBM with no announced end-of-life date \u2014 serving thousands of organizations in air-gapped, regulated, and strict data residency environments. In May 2025, IBM launched the QRadar Investigation Assistant, powered by watsonx generative AI, to accelerate on-premises security investigations by summarizing offenses and generating remediation recommendations. On-premises watsonx integration was announced in early 2026 for regulated customers. QRadar on-premises also supports 3,000+ open-source Sigma rules for flexible community-maintained detection, 750+ third-party integrations, IBM X-Force threat intelligence, and User Behavior Analytics for insider threat detection.

IBM QRadar SIEM is the right choice for large enterprises and government agencies in 2026 that require strict on-premises deployment for air-gapped or data residency compliance, have significant existing QRadar investments, and cannot move to cloud SIEM platforms \u2014 particularly those leveraging IBM X-Force threat intelligence and IBM Consulting for managed security services.

IBM QRadar SIEM (on-premises) uses enterprise custom pricing with no public list price. All contracts require direct engagement with IBM sales.

On-premises pricing is based on Events Per Second (EPS) ingestion volume, Flows Per Minute (FPM) for network traffic analysis, deployment size, and selected add-on modules (UBA, QRadar SOAR, X-Force Threat Intelligence). Reference pricing from verified buyer reports: approximately $50,000\u2013$200,000+/year for mid-size enterprises, scaling significantly for large government and financial services deployments.

Note: QRadar SaaS, QRadar Cloud, and QRadar EDR/XDR SaaS products are no longer available \u2014 those were sold to Palo Alto Networks in September 2024 and have reached end-of-life. The available IBM product is QRadar SIEM on-premises only. Contact IBM at ibm.com/products/qradar-siem for enterprise pricing.
