Understanding SCIM and Directory Sync

System for Cross-domain Identity Management (SCIM) is an open standard that automates user provisioning and de-provisioning, facilitating efficient user lifecycle management (ULM) by syncing user identity data between Identity Providers (IDPs) like Okta and OneLogin, and Service Providers (SPs) such as Enterprise SaaS apps. Directory Sync, which relies on SCIM protocols, streamlines this process by enabling automatic updates to user identities, thus saving IT resources and reducing errors associated with manual handling, especially in large organizations. Implementing Directory Sync can be labor-intensive and complex if done in-house, but using open-source solutions like Ory Polis can simplify the process by providing easy integration with multiple IDPs, minimizing the need for extensive engineering work. Ory Polis enhances efficiency by notifying SPs of changes in user identity data through Webhook endpoints, offering a scalable, secure, and maintainable solution for managing user data across various platforms.
