- 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; OneTrust complex usage-based pricing model with multiple meters (admin users, inventory size, daily visitors, data subjects) making total cost unpredictable

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
OneTrust
- Complex usage-based pricing model with multiple meters (admin users, inventory size, daily visitors, data subjects) making total cost unpredictable
- No published pricing examples or per-unit costs; all pricing requires custom quotes
- Each solution area uses different pricing metrics, requiring complex calculations for multi-solution purchases
- Enterprise-only positioning (Fortune 500 focus) suggests premium pricing, discouraging mid-market or startup adoption
- Platform complexity and multiple solution areas may result in significant implementation and ongoing costs not disclosed upfront
