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.

Fathom Analytics

  • There is no free tier, only a 7 day trial
  • Priced on pageviews, from $45 a month at the 500,000 pageview level
  • Custom events count against the pageview allowance rather than being tracked separately
  • Site allowances come in packs, with additional 50-site packs at $10 a month
  • Data is retained forever only while the subscription is active

Answered from the vendors’ own pages

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.

Fathom Analytics: How much does Fathom Analytics cost?

Fathom's entry-level plan costs $45/month for up to 500,000 pageviews. Higher volume tiers exist (1M, 2M, 10M, 25M+ pageviews) with custom pricing. Yearly billing provides 2 months free.

DataGrail: Does it find systems we do not know about?

Yes. Continuous discovery of unsanctioned tools processing personal data is its main technical claim.

Fathom Analytics: Is there a free trial for Fathom Analytics?

Yes, Fathom offers a 7-day free trial. There is no free tier after the trial ends.

Source
DataGrail: What does it cost?

Not published. Pricing is quoted by request volume and connected systems, with multi-year commitments typically discounted.

Fathom handles usage overage graciously, only upgrading your plan after two consecutive months over your limit. There are no immediate overage charges.

Source
DataGrail: Does it cover consent as well as requests?

Yes, it includes consent management, though publishers needing certified advertising consent usually use a specialist CMP.
