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.
PaidMicrosoft Defender for Endpoint has two standalone tiers and M365 bundle pricing: Plan 1 (standalone): $3/user/month \u2014 next-gen antivirus, attack surface reduction, device control, web protection. Prevention-only. Included in M365 E3 ($36/user/month). Plan 2 (standalone): $5.20/user/month \u2014 full EDR, behavioral AI, AIR, 6-month retention, Live Response, KQL threat hunting. Included at no cost in M365 E5 ($60/user/month) and E5 Security add-on ($12/user/month on E3). M365 Business Premium ($22/user/month, up to 300 users) includes Defender for Business. Copilot for Security ~$4/SCU/hour billed separately.

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
Microsoft Defender for Endpoint

Microsoft Defender for Endpoint Pros & Cons

Pros

  • Zero incremental cost for M365 E5 subscribers — Plan 2 full EDR included, most cost-effective for Microsoft shops
  • Native Windows/Azure/M365/Intune integration — unmatched ecosystem coherence for Microsoft enterprises
  • Defender XDR unifies endpoint, email, identity, cloud apps, and cloud signals — broadest cross-domain correlation
  • Copilot for Security GenAI SOC assistant — incident summarization, script deobfuscation, natural-language hunting
  • 35,000+ ransomware incidents disrupted monthly — proven at unprecedented real-world scale
  • FedRAMP High compliance — approved for US federal government deployments
  • AIR autonomous triage reduces tier-1 SOC analyst workload significantly

Cons

  • Full EDR requires Plan 2 or M365 E5 — Plan 1 is prevention-only with no investigation or threat hunting
  • Copilot for Security consumption-based (~$4/SCU-hour) — costs scale unexpectedly for heavy SOC use
  • Advanced hunting requires KQL expertise — steeper than Charlotte AI natural language
  • MacOS and Linux support less mature than Windows in some edge cases
  • Complex M365 E3/E5/standalone/bundle licensing creates confusion and duplicate spend risk
