CIAM Providers Compared

Short answer. CIAM providers fall into four groups: broad identity platforms, B2B-focused CIAM platforms, developer-first authentication services and open-source identity servers. For business customers, compare them on organizations, delegated administration, partner sign-in and authorization, then test them in a proof of concept.

The categories of CIAM provider

• Broad identity platforms that cover workforce and customer identity in one portfolio.
• B2B-focused CIAM platforms built around customer organizations, delegated administration and partner sign-in.
• Developer-first authentication services that add sign-in and organizations to an application through APIs and prebuilt components.
• Open-source identity servers you host and operate yourself.

Who are the top CIAM vendors?

• SecureAuth: CIAM built for business customers and partners, with organizations and sub-organizations, delegated administration, per-organization sign-in and policy-based authorization.
• Auth0: a CIAM platform with organizations and a large developer ecosystem.
• Microsoft Entra External ID: Microsoft's customer identity service, a natural fit for Microsoft-centric teams.
• Ping Identity: enterprise identity, now including ForgeRock.
• Clerk: developer-first authentication with prebuilt components and organizations.
• WorkOS: developer-first enterprise sign-in for B2B software, including SSO and directory sync.

Evaluation criteria that separate vendors

• Organization model: flat or nested, and what an organization can own.
• Delegated administration: what a customer's administrator can do, and what stays with you.
• Partner sign-in: connecting each partner's identity provider, making it mandatory, and serving partners with none.
• Authorization: whether permissions are decided per organization and per API, and how policies are written.
• Lifecycle and audit: what happens on role changes and departures, including open sessions, and what is recorded.
• Extensibility: APIs, events and custom logic.
• Cost model: what you pay for as users and organizations grow.

How to run a 30-day CIAM proof of concept

• Week 1: set up your real user model: two customer organizations, one with sub-organizations, and a consumer flow if you have one.
• Week 2: test partner sign-in both ways: one organization through its own identity provider, made mandatory, and one through hosted sign-in.
• Week 3: test the lifecycle: a new joiner, a role change, a leaver with an open session, and a person in two organizations.
• Week 4: test administration and audit from the customer administrator's seat, check the events you need, and score each vendor against your criteria.
