Cybersecurity
Entity resolution and network analytics for financial crime investigation
- From
- On request
- Rated
- -
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; Quantexa pricing is never published and lands in the seven figure range annually for a tier one deployment, so it is out of reach for mid-sized institutions no matter how well the analytics would fit.
- They diverge on capability: Microsoft Sentinel covers AI-powered analytics, Quantexa covers Entity resolution.
- Prices and features above were last checked on 1 September 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
Quantexa
- Pricing is never published and lands in the seven figure range annually for a tier one deployment, so it is out of reach for mid-sized institutions no matter how well the analytics would fit.
- Output quality is bounded by input data quality, and organisations without governed customer data spend the first phase of the programme fixing feeds rather than catching criminals.
- Implementation typically requires a systems integrator and runs into quarters rather than weeks, so the business case has to survive a long period with no operational benefit.
- The platform augments rather than replaces existing transaction monitoring, so you keep paying for the incumbent system alongside it and total compliance technology spend rises before it falls.
- Skills are scarce; the platform needs people who understand both Spark scale data engineering and financial crime typologies, and those people are hard to recruit and easy to lose.
