Implementation of Keycloak as a Central IAM Platform
Keycloak was implemented as the central identity and access management platform.
The following were included:
- implemented modern authentication and SSO mechanisms
- integrated with existing user structures
- standard-based interfaces are used to integrate systems flexibly
including authentication, user migration and system integration
Seamless integration with existing systems
Existing systems and users were gradually migrated to the new platform.
The following were included:
- Users, including passwords, have been migrated
- integrated with existing applications
- Directory services integrated
- Logging and monitoring structures established
including migration, integration, and log forwarding
A Secure and Future-Proof Platform
The platform is operated as a scalable Keycloak-as-a-Service solution.
The result for the customer:
- zentralized and secure authentication
- reduced complexity in user management
- easy integration of new applications
- stable operation through structured update and release processes
includes staging, updates, and operation of the environment
