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.
PaidSentinelOne offers five pricing tiers based on per-endpoint annual licensing: Singularity Core: ~$69.99/device/year \u2014 EPP and basic endpoint protection. Singularity Control: $79.99/device/year \u2014 adds firewall management, device control, and cloud workload protection. Singularity Complete: $179.99/device/year \u2014 adds full EDR, XDR, Storyline, Purple AI, and 14-day data retention. Singularity Commercial: $229.99/device/year \u2014 adds identity threat detection, managed threat hunting, and 90-day data retention. Singularity Enterprise: custom pricing \u2014 adds agentic AI SOC analyst, full forensics, and 24/7 MDR. Starting price is approximately $5.83/endpoint/month. Enterprise pricing is custom-quoted via the sales team. Vigilance MDR can be added as a managed service layer on any tier. A 30-day free trial is available.

Summary
Cloud-native SIEM+SOAR on Azure — AI threat detection, KQL hunting, and native M365 integration
Autonomous AI XDR with offline EDR, one-click ransomware rollback, Purple AI, and 100% MITRE coverage
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
SentinelOne

SentinelOne Pros & Cons

Pros

  • Autonomous on-device AI — detection and response continues even when endpoints are offline or air-gapped
  • One-click ransomware rollback via VSS — restores encrypted files instantly without manual intervention
  • 100% MITRE ATT&CK detection coverage (2024) — best-in-class independent detection benchmark result
  • Storyline ActiveEDR auto-correlates attack events into visual narratives — eliminates manual investigation
  • Purple AI (first LLM natively in XDR) — natural-language threat hunting and agentic investigation from Complete tier
  • $1.001B FY2026 revenue, $1.055B ARR — proven scale with 22-24% YoY growth on NYSE
  • Unified platform: endpoint + identity (Attivo) + cloud (PingSafe) + AI-SIEM + MDR in one agent

Cons

  • Pricing is largely quote-based at higher tiers — harder to budget upfront vs CrowdStrike’s published list pricing
  • EDR, data retention, Storyline, and Purple AI only available from the Complete tier ($179.99/device/yr) and above
  • Still GAAP unprofitable despite $1B+ ARR — -$451M GAAP net loss in FY2026
  • Advanced features require significant SOC expertise to fully leverage
  • Cross-platform macOS/Linux coverage is less mature than Windows in some edge cases
