CIAM vs. IAM: What's the difference, and why it matters for B2B SaaS

IAM (Identity and Access Management) and CIAM (Customer Identity and Access Management) are both concerned with identifying individuals and determining their access rights, but they cater to different audiences. IAM is typically used for managing workforce identities within an organization, focusing on control, compliance, and lifecycle management, with tools like SCIM provisioning and role-based access control. Conversely, CIAM is aimed at managing external users such as customers and partners, prioritizing seamless signup processes and user experience to minimize friction and support growth. The distinction between these two systems is crucial, as a system designed for workforce management can create barriers for customer conversion, while a customer-focused system may lack the governance and audit capabilities needed for workforce management. Many organizations, therefore, operate separate systems for IAM and CIAM, even if a single vendor offers both solutions. In B2B SaaS environments, the lines between IAM and CIAM can blur as customers often require enterprise-grade features like single sign-on, which is where WorkOS provides a solution. WorkOS offers pre-built connectors for enterprise identity features like SCIM provisioning and directory sync, bridging the gap between customer and workforce identity needs without requiring extensive development efforts from engineering teams.
