Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
GitLab CI/CD
- Compute minute quotas for Premium and Ultimate tiers not disclosed in documentation
- Additional compute minutes beyond quota incur charges; exact pricing not specified
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
