What is Customer Identity and Access Management (CIAM)?

Customer Identity and Access Management (CIAM) is a specialized branch of IAM that manages the identities of external customers and consumers rather than internal employees. It handles registration, authentication, consent, and profile management at large scale, balancing strong security with a smooth user experience while complying with privacy regulations such as GDPR.

How CIAM works

  • Lets customers self-register and authenticate (including social and passwordless login).
  • Manages consent and privacy preferences in line with GDPR.
  • Scales to millions of external identities with low friction.
  • Personalizes experiences using progressive profiling.
  • Protects against fraud, bot signups, and account takeover.

CIAM vs workforce IAM

CIAM and workforce IAM serve different audiences. CIAM addresses external customers and consumers, prioritizing experience, scale, and consent for millions of users, and is typically driven by marketing and product. Workforce IAM addresses internal employees and contractors, prioritizing control, governance, and lifecycle for hundreds to thousands of users, and is driven by IT and security.

Examples and use cases

A SaaS vendor uses CIAM so its end users sign up, log in with a passkey, and manage consent, all at scale. This is distinct from how the same vendor manages its own staff. Corma focuses on the workforce side: governing employee access, SaaS usage, and licenses internally. CIAM is the customer-facing counterpart, and the two rarely use the same tooling.

FAQ

What is the difference between CIAM and IAM?

‍CIAM manages external customer identities with a focus on scale and experience. Workforce IAM manages internal employees with a focus on governance and control.

Does Corma provide CIAM?

‍Corma focuses on workforce IAM and SaaS Management, which govern internal employee access and software. CIAM is a separate, customer-facing discipline.

Why is consent central to CIAM?

‍Because CIAM handles consumer data, it must capture and honor privacy consent under regulations like GDPR, which is less prominent in workforce IAM.

For governing internal employee access and SaaS, Corma is the workforce IAM and SaaS Management layer. Request a demo.
