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

Sumsub

  • The published per-verification rate is undercut by a monthly minimum of 149 or 299 dollars, so low volume businesses pay a much higher effective rate than the headline suggests.
  • You are billed per verification attempt in most configurations, meaning applicant drop-off and resubmissions cost money without producing a customer.
  • Pass rates and document support vary noticeably by country, and a market that works well in Europe can produce materially worse rejection rates in parts of Africa and South East Asia.
  • The AML screening tier bundles list coverage that large institutions would normally buy separately and tune, giving less control over match thresholds than a dedicated screening vendor.
  • The company originated in Russia before restructuring to a UK entity, and some financial institutions still raise that history in vendor risk review, which can slow or block procurement at conservative banks.
