The short version

  • Only Microsoft Sentinel has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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; Tanium no public pricing is published, requiring a sales engagement to get a quote.
  • They diverge on capability: Microsoft Sentinel covers AI-powered analytics, Tanium covers Real-time endpoint queries.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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
  • Commitment tier discounts require reserving daily ingestion capacity in advance, and a tier cannot be downgraded until 31 days have passed
  • Commitment tiers start at 100 GB per day, above what smaller estates ingest
  • Charges for Log Analytics, Logic Apps and Machine Learning are billed separately on top of Sentinel itself
  • The free allowance is only up to 5 MB per user per day for selected Microsoft 365 security logs
  • Promotional commitment pricing is time limited and locks in only until a stated end date

Tanium

  • No public pricing is published, requiring a sales engagement to get a quote.
  • Aimed at large enterprises, making it impractical for small teams or budgets.
  • Deployment and configuration of the agent-based architecture requires significant IT expertise.
  • Full value depends on adopting multiple Tanium modules, which can increase cost and complexity versus point solutions.
