The short version

  • Each has a real cost: 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.; One Identity the portfolio is assembled from separate acquisitions, so components are separately licensed, separately administered and do not present one console, which raises operational cost.
  • They diverge on capability: Entrust Identity as a Service covers Multi-factor authentication, One Identity covers Identity Manager.
  • Prices and features above were last checked on 1 September 2026.

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.

One Identity

  • The portfolio is assembled from separate acquisitions, so components are separately licensed, separately administered and do not present one console, which raises operational cost.
  • Identity Manager implementations are customisation-heavy and commonly run over a year, with the services spend exceeding the licence cost in the first year.
  • Quest has changed private equity ownership more than once since the Dell separation, and buyers should ask directly about product investment commitments before signing a multi-year deal.
  • Product documentation and support sit behind a customer portal, which makes independent evaluation before purchase harder than with vendors that publish openly.
  • The cloud-native and developer experience trails the pure-play identity vendors, so organisations moving decisively to SaaS applications find the on premises heritage becomes a constraint rather than an asset.

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.

One Identity: Is One Identity the same company as Quest?

Yes. One Identity is Quest Software's identity and access management business unit, not a separate vendor.

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.

One Identity: Does it include privileged access?

Safeguard provides it, but it is licensed separately from Identity Manager. Neither includes the other.

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.

One Identity: Why choose this over SailPoint or Saviynt?

Almost always because of Active Directory depth via Active Roles or an appliance requirement for privileged sessions. For cloud-first estates the specialists are the stronger choice.
