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 Defender
- Defender Suite requires existing Microsoft 365 E3 or equivalent base licensing
- Some Defender products use pay-as-you-go pricing with variable costs
- Prices vary based on Microsoft agreements, requiring sales contact for custom quotes
