  • They diverge on capability: Entrust Identity as a Service covers Multi-factor authentication, Sardine covers Device intelligence.
  • 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.

Sardine

  • Signal quality depends on the SDK being embedded in your own web and mobile clients, so fraud improvements become dependent on your app release cycle and any coverage gap is a blind spot.
  • Behavioural and device telemetry collection needs a documented lawful basis under GDPR, and EU privacy reviews frequently delay rollouts that were scoped as engineering work.
  • Pricing is per session or per active user, so a consumer product with many low value sessions pays in proportion to traffic rather than to fraud exposure.
  • As a younger private company it lacks the enforcement-tested audit history that a bank examiner expects, which makes it a harder sell inside a regulated bank than inside a fintech.
  • It is strongest on session-time signals and weaker as a system of record for long horizon AML typologies, so larger institutions end up running it alongside a traditional monitoring platform rather than instead of one.

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.

Sardine: Does Sardine do document verification?

It focuses on device, behavioural and transaction signals, and integrates identity verification providers rather than being one. Treat it as complementary to a KYC 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.

Sardine: What does it need from us to work?

An SDK in your web and mobile applications plus transaction feeds. Without the client side collector you lose the signals that differentiate it.

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.

Sardine: Is pricing published?

No. It is quoted, typically per session or per monthly active user with an annual volume commitment.
