Pricing
PaidMicrosoft Sentinel uses consumption-based pricing with two primary models: Pay-As-You-Go (PAYG): ~$2.46-$5.20/GB of data ingested (varies by region). Best for organizations with variable or unpredictable ingestion below 50 GB/day. Commitment Tiers: Fixed daily rates offering 31-52% savings vs PAYG. Starts at 100 GB/day ($123/day = ~$3,690/month, ~$1.23/GB effective). Scales to 50,000 GB/day with the highest discounts. You pay the tier rate even on days when ingestion falls below the commitment. Three log tiers for cost optimization: Analytics Logs (full rate, real-time detection), Basic Logs ($1.12/GB, limited KQL), and Auxiliary Logs ($0.19/GB for cold/archival data). Many Microsoft data sources (M365 Defender alerts, Azure AD Identity Protection, Defender for Cloud) ingest at no additional Sentinel charge. Copilot for Security is priced separately at ~$4/SCU/hour. Contact Microsoft at azure.microsoft.com/sentinel for enterprise pricing.
EnterpriseIBM 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.

Summary
Cloud-native SIEM+SOAR on Azure — AI threat detection, KQL hunting, and native M365 integration
IBM's AI-powered on-premises SIEM — 30+ years of threat detection with watsonx GenAI investigation
Microsoft Sentinel

Microsoft Sentinel Pros & Cons

Pros

  • 50-60% lower cost than Splunk Enterprise Security at equivalent ingestion volumes — significant TCO advantage
  • Zero infrastructure management — cloud-native SaaS SIEM with elastic scaling and no hardware or patching
  • Native SOAR included free — 200+ Logic Apps playbooks at no additional license, unlike Splunk SOAR
  • Native Defender XDR integration — M365, Azure AD, and Defender alerts ingest with zero connector overhead
  • Three-tier log pricing (Analytics/Basic/Auxiliary) — cost-optimize ingestion by routing cold data cheaply
  • 8,500+ Microsoft security experts — continuously updated threat intelligence and detection content
  • M365 E5 benefit — 5 MB/user/day free Sentinel data allowance for M365 E5 subscribers

Cons

  • Cloud-only (Azure) — no on-premises deployment option, unsuitable for air-gapped or strict data residency environments
  • KQL requires specialized training — different from Splunk’s SPL and SQL, creating skill gap for analysts switching platforms
  • Copilot for Security is consumption-priced separately — heavy GenAI SOC use adds $4/SCU/hour on top of Sentinel costs
  • Smaller third-party app ecosystem than Splunk’s 2,800+ Splunkbase apps — fewer community detection packs
  • Commitment tier billing is inflexible — paying the committed daily rate even on low-ingestion days with no refund
IBM QRadar SIEM

IBM QRadar SIEM Pros & Cons

Pros

  • 30+ years of enterprise SIEM heritage — battle-tested in the world’s largest and most complex security environments
  • watsonx GenAI Investigation Assistant (May 2025) — on-premises AI investigation without sending data to external cloud
  • 3,000+ Sigma rules — community-maintained detection logic that stays current as threats evolve
  • IBM X-Force Threat Intelligence integration — one of the most respected threat research teams in the industry
  • On-premises deployment for strict data residency — the go-to SIEM for air-gapped, government, and regulated environments
  • 750+ integrations in IBM Security app marketplace — broadest third-party connector library after Splunk
  • On-prem QRadar SOAR remains fully supported — no announced end-of-life for automation workflows

Cons

  • QRadar SaaS/Cloud assets sold to Palo Alto Networks (Sep 2024) — cloud version reached EOL April 14, 2026; only on-premises remains under IBM
  • QRadar EDR and XDR SaaS reach end-of-life August 31, 2026 — significant platform uncertainty for existing cloud customers
  • IBM’s long-term engineering investment unclear after SaaS divestiture to Palo Alto Networks
  • Steep learning curve — less intuitive interface than modern SIEMs like Microsoft Sentinel or Exabeam
  • On-premises-only going forward limits cloud-native scalability and modern SaaS delivery model
