TL;DR: Gartner’s Innovation Insight for Customer and Partner IAM argues that more than half of organisations still rely on homegrown CIAM or no solution at all, according to Descope’s reading of the report, while external identity demands are becoming more dynamic and security-sensitive. The governance problem is no longer authentication alone but whether identity architecture can support transient users, partner ecosystems, and modern protocols without overloading workforce IAM assumptions.
Editorial analysis by NHI Mgmt Group, based on content published by Descope: “Reflections on the 2025 Gartner® Innovation Insight for Customer & Partner IAM”.
By the numbers:
- Over 50% of organizations are using either homegrown CIAM solutions or no solution at all.
- Gartner published its Innovation Insight for Customer and Partner Identity and Access Management on 28 April 2025.
Key questions
Q: What breaks when organisations use workforce IAM for customer identity journeys?
A: The usual failure mode is rigidity.
Q: Why do customer and partner IAM programmes need different governance than employee IAM?
A: Because external identities are governed by relationship and usage context, not by employment status.
Q: How should teams decide whether to build or buy CIAM and PIAM capabilities?
A: Teams should evaluate whether they can sustain modern protocol support, external identity journey design, and security updates without pulling core engineering away from product work.
Practitioner guidance
- Separate external identity from workforce IAM Define CIAM and PIAM as distinct programme scopes with different lifecycle rules, UX expectations, and risk controls instead of folding them into employee IAM workstreams.
- Model stakeholder types explicitly Map customers, partners, vendors, and tenant admins as separate identity constituencies so journey design, consent handling, and administrative privileges reflect real relationships.
- Keep protocol logic in the identity layer Centralise federation, adaptive authentication, and session decisions in the identity control plane rather than embedding them in application code.
Bottom line: Customer and partner IAM has different lifecycle and trust assumptions from workforce IAM, so employee-centric controls are a poor default fit.

External IAM is no longer a subset of workforce IAM. The article’s central argument is that customer and partner identity has different operating assumptions, different security expectations, and different lifecycle realities. Workforce IAM can authenticate an employee, but it does not automatically govern a transient customer, a partner admin, or a multi-tenant business relationship. Practitioners should stop treating external identity as an extension of employee access and start treating it as its own governance domain.
A question worth separating out:
Q: What is the difference between B2C and B2B in mature external IAM?
A: In mature external IAM, B2C and B2B are not hard programme boundaries. They are collections of identity functionality for individuals and organisations that often coexist in the same customer, partner, or vendor ecosystem. The practical difference is that identity architecture must support both constituency types without forcing one rigid model across every external relationship.
