Where each one falls short

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

GNAT Pro

  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs

iDenfy

  • Rates are quoted rather than published on an accessible page, so despite the marketing emphasis on transparency you still need a sales conversation to get a number.
  • It is a smaller vendor than the market leaders, which makes it a harder sell through enterprise vendor-risk review even when the product performs well.
  • Human review on every case caps throughput in a way fully automated competitors are not constrained by, which shows up as latency during volume spikes.
  • Coverage and accuracy are strongest on European documents; performance on some Asian, African and Latin American document types trails specialists in those regions.
  • The bundled AML screening uses its chosen data sources, so institutions mandated to use a specific list provider such as Dow Jones cannot substitute it and end up paying twice.
