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.

OpenCities

  • Population-based pricing model limits scalability for growing municipalities
  • No self-hosted or on-premises deployment option
  • Limited code customization without vendor support

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.

OpenCities: Does OpenCities work offline?

No, OpenCities is a cloud-based SaaS platform that requires an internet connection. All editing and management is done through web browsers.

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.

OpenCities: What accessibility standards does OpenCities meet?

OpenCities is maintained to comply with WCAG AA requirements, ensuring equitable access to government services and information for all residents.

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.

OpenCities: Can I integrate OpenCities with other government systems?

Yes. OpenCities integrates with Google Analytics, govDelivery for notifications, EngagementHQ for feedback collection, Legistar for meeting management, and Active Directory for intranet workflows.
