The text highlights the differences between Customer Identity and Access Management (CIAM) and Identity and Access Management (IAM). While both systems aim to manage user identities, they serve distinct purposes. IAM is primarily focused on managing employee identities, with a focus on security, scalability, and hierarchical permission structures. In contrast, CIAM is designed for customer identity management, prioritizing customer experience, localization, and consumer-grade user interfaces. CIAM solutions are built for scale and flexibility to accommodate large numbers of customers with varying access requirements. The key differences between CIAM and IAM lie in their respective focus on employee versus customer identities, security protocols, and permission structures.
