  • They diverge on capability: AdBlock Plus covers Ad blocking, DataGrail covers Live data discovery.

DataGrail

  • A consumer brand whose deletion requests keep missing data in marketing tools the privacy team did not know existednot AdBlock Plus
  • A company processing hundreds of CCPA requests a month where manual fulfilment has become a full-time jobnot AdBlock Plus

  • An organisation needing evidence for a regulator that deletion actually occurred in every system, not that a ticket was closednot AdBlock Plus

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

AdBlock Plus

  • Acceptable Ads allowlist model generates controversy over ad filtering conflicts of interest
  • Smaller feature set compared to open-source alternatives like uBlock Origin
  • Less customization and dynamic filtering compared to uBlock Origin
  • Mobile version less comprehensive than desktop extension
  • Chrome version increasingly limited due to Manifest V3 migration

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.
