Where each one falls short

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

Entrust Identity as a Service

  • The application integration catalogue is smaller than that of the dedicated identity vendors, so uncommon SaaS applications more often need custom SAML configuration rather than a template.
  • Developer experience for customer identity use cases is behind the specialists, and teams building consumer signup flows will find the APIs and documentation less complete.
  • Advanced capabilities including adaptive authentication and credential management sit above the published entry price, so the two dollar figure rarely reflects what a regulated buyer actually spends.
  • There are two overlapping products, Identity as a Service and Identity Enterprise, and choosing wrongly at the start means a migration later rather than a licence change.
  • Identity governance, access certification and privileged access are not covered, so an organisation with audit-driven access review requirements needs a second vendor alongside it.

Keygen

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

Answered from the vendors’ own pages

Entrust Identity as a Service: Is MFA included or extra?

Multi-factor authentication is included in the workforce bundles rather than sold separately, which is not true of every competitor. Adaptive risk-based authentication sits in higher tiers.

Keygen: Does Keygen have a free tier?

Yes, the Dev tier is free and supports up to 100 Active Licensed Users with 10 product releases and core licensing API access.

Source
Entrust Identity as a Service: Does it do identity governance?

No. Access certification, role mining and joiner-mover-leaver governance require a separate product such as SailPoint or Saviynt.

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
Entrust Identity as a Service: Why choose this over Okta or Entra ID?

Almost always because of PKI, smart cards or derived credentials. Without that requirement the mainstream platforms are the stronger general purpose choice.

Keygen: Does Keygen charge for additional features like SSO?

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