Scalekit SCIM Provisioning is a System for Cross-domain Identity Management implementation that enables automated user lifecycle management for enterprise applications. The product provides a single API for integrating with multiple enterprise directory systems. The solution automates user provisioning by synchronizing users from enterprise directories to applications without manual intervention. It handles user creation, updates, and deactivation based on changes in the source directory system. The product supports automated role assignment through directory groups and custom attributes. Administrators can map roles and permissions based on group memberships and custom user attributes defined in enterprise directories. User deprovisioning is automated to remove access when users are deactivated or removed from the source directory. This reduces security risks associated with orphaned accounts and eliminates the need for manual access revocation. The platform supports custom attribute mapping to extend standard SCIM schema with application-specific user attributes. It provides webhooks for event-driven workflows and includes audit logging capabilities for tracking provisioning activities. The solution is designed for B2B SaaS applications that need to support enterprise customer requirements for automated user management. It integrates with existing authentication systems without requiring migration of user databases.
