Client

A leading European bank serving millions of retail, corporate, and investment customers across multiple digital channels. As one of the largest financial institutions in the region, the bank continuously invests in technology to enhance security, improve user experience, and accelerate digital transformation.

Challenge

The bank’s legacy Identity and Access Management (IAM) infrastructure had become fragmented and outdated. Multiple IAM servers lacked support for modern standards such as OpenID Connect, OAuth 2.0, SCIM, and SAML, and did not provide Single Sign-On (SSO), Multi-Factor Authentication (MFA), or user federation capabilities.

Authentication and authorization logic were tightly coupled with business applications, resulting in complex workflows, difficult maintenance, and limited flexibility. The absence of autoscaling and configurable IAM features slowed down the development cycle and made it challenging to respond to new business and security requirements.

Additionally, legacy integrations limited support for multi-channel platforms—mobile, web, and APIs—leading to inconsistent and inefficient user experiences.

Project journey

To modernize the client’s IAM ecosystem, our team designed and implemented a centralized, on-premise Keycloak-managed service that unified all existing IAM servers under a single, secure, and scalable platform.

  • Implementing Keycloak as a centralized authorization and authentication platform.
  • Deploying a microservice-based architecture on Kubernetes for scalability and high availability
  • Consolidating legacy IAM systems into one unified solution to simplify operations and reduce maintenance overhead.
  • Introducing configurable authentication and authorization flows to improve agility and strengthen security.
  • Integrating Keycloak with Active Directory, custom user storage, and legacy systems to enable flexible user federation.
  • Establishing multi-channel support for mobile, web, and API-based applications.
  • Setting up a new CI/CD pipeline to accelerate release cycles and updates.
  • Emphasizing a configuration-driven approach for faster adaptation to evolving requirements.
  • Enabling continuous monitoring and optimization to maintain peak performance and security.

Results

  • Unified all IAM systems into a single, scalable Keycloak-based platform.
  • Enhanced user experience with secure SSO, MFA, and multi-channel access.
  • Improved security and compliance through centralized policies and modern standards (OAuth 2.0, OpenID Connect, SAML, SCIM).
  • Accelerated delivery and adaptability with a configuration-driven, CI/CD-enabled architecture.
