Where each one falls short

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

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.

Keycloak

  • Requires self-hosted deployment and operational expertise to install, configure and maintain
  • No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
  • Clustering and high-availability configurations require additional operational knowledge
  • Community support only; commercial support requires third-party vendors or distributions

Keycloak supports OpenID Connect, OAuth 2.0 and SAML 2.0 protocols for authentication and authorisation.
