Where each one falls short

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

Feedzai

  • Pricing is per transaction with an annual minimum, so a bank with seasonal or growing volume commits to a floor it may not use and pays overage above the band.
  • It sits in the authorisation path, which makes every upgrade a change-controlled event with rollback plans, and the operational burden falls on the bank rather than the vendor.
  • Out of the box models need months of the customer own labelled fraud history before they beat the rules they replace, so the value case starts late.
  • AML and fraud are licensed as separate modules, so institutions expecting one platform fee find the transaction monitoring capability is a second line item.
  • The buyer profile is large institutions, so smaller banks and fintechs face minimums that make per-transaction economics unattractive below significant scale.

Keygen

  • Specific Active Licensed User (ALU) pricing not listed; requires interactive pricing calculator
  • Whitelabel API add-on costs $995/year per domain

It does, but transaction monitoring is a separately licensed module. Assume two line items if you want both.

Keygen: How is Keygen pricing calculated?

Keygen uses scalable, flat monthly or yearly fees based on your licensing volume (Active Licensed Users). No revenue share or transaction fees are charged.

Source
Feedzai: How fast are decisions?

SAML/SSO is included in Enterprise tiers. Whitelabel API support costs $995/year per domain. Premium Support SLA is $995/month for Enterprise.
