The short version

  • Only Proton Mail has a free tier, so it costs nothing to try first.
  • Each has a real cost: Proton Mail paid plan pricing not displayed on vendor site; Trulioo per-check rates vary widely by country and data source, so a blended average from the sales conversation misleads if your volume concentrates in expensive markets.

Where each one falls short

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

Proton Mail

  • Paid plan pricing not displayed on vendor site
  • Free tier limited to 1 GB storage
  • Free tier limited to single email address

Trulioo

  • Per-check rates vary widely by country and data source, so a blended average from the sales conversation misleads if your volume concentrates in expensive markets.
  • Coverage breadth is real but depth is uneven; a country on the map may be served by one thin source with low match rates, which you only discover in a live test.
  • You are charged per query including no-match results, so a market with poor source coverage burns budget producing nothing usable.
  • Because it aggregates third-party data, data residency and consent handling depend on the underlying provider terms, which complicates GDPR assessments in some jurisdictions.
  • Document and biometric capability is competent but not the strongest in the market, so buyers whose primary need is document fraud detection usually pair it with a specialist.
