The short version

  • Only Microsoft Sentinel has a free tier, so it costs nothing to try first.
  • Each has a real cost: Azure Government restricted to US government entities, their solution providers and contractors handling government data, with Microsoft validating eligibility first; Microsoft Sentinel billing is driven by the volume of log data ingested per day, so cost scales with log noise rather than with users or protected assets
  • They diverge on capability: Azure Government covers FedRAMP High Authorized, Microsoft Sentinel covers AI-powered analytics.
  • Prices and features above were last checked on 30 August 2026.
