DataGrail
Cybersecurity
Privacy platform that finds shadow data systems and automates data subject requests across them
- 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: DataGrail no pricing is published, and while benchmarking suggests it undercuts OneTrust for comparable scope, cost still scales with request volume and connected systems, which grow with the business.; 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: DataGrail covers Live data discovery, Microsoft Sentinel covers AI-powered analytics.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
DataGrail
- No pricing is published, and while benchmarking suggests it undercuts OneTrust for comparable scope, cost still scales with request volume and connected systems, which grow with the business.
- Automated fulfilment only works for systems with a supported connector, so homegrown applications and legacy databases still need manual handling, and those are usually where the awkward data lives.
- Discovery works by observing integrations and traffic patterns, so genuinely isolated systems, offline data and files on employee machines remain invisible and outside the data map.
- It is narrower than the enterprise privacy suites, lacking the assessment, third-party risk and wider GRC modules a large regulated organisation will also need, so it may be one of two platforms rather than the only one.
- Deletion automation is irreversible and mistakes are unrecoverable, so teams need real confidence in identity verification before enabling it, and that caution often keeps deletion semi-manual for months after purchase.
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

Answered from the vendors’ own pages
DataGrail: How is DataGrail different from OneTrust?
OneTrust orchestrates the workflow; DataGrail focuses on connecting to systems and completing the request, and benchmark data suggests it prices materially below OneTrust for comparable scope.
Microsoft Sentinel: How is Microsoft Sentinel pricing calculated?
Microsoft Sentinel uses a pay-as-you-go usage-based model where you pay only for data ingested, stored, and consumed. Flexible commitment tiers are available to reduce total cost of ownership, with specific rates not published on the public pricing page.

SourceDataGrail: Does it find systems we do not know about?
Yes. Continuous discovery of unsanctioned tools processing personal data is its main technical claim.
Microsoft Sentinel: Does Microsoft Sentinel require an Azure subscription?
Yes, Microsoft Sentinel requires a Microsoft Azure subscription to operate. Pricing is handled through Azure and varies based on data consumption and the commitment tier you select. Source: https://www.microsoft.com/security/business/siem-and-xdr/microsoft-sentinel/
SourceDataGrail: What does it cost?
Not published. Pricing is quoted by request volume and connected systems, with multi-year commitments typically discounted.
