Abstract: Implementing Keycloak as an identity management solution within SASE architectures presents a strategic approach to modern security challenges. The Regional Hub Model effectively addresses authentication complexities in distributed SASE environments where continuous identity verification supports Zero Trust principles. SASE architectures struggle with complex challenges stemming from the need to support multiple tenants and connect with various identity systems within organizations. These architectural hurdles demand thoughtful solutions that address both technical and operational needs. Strategically positioning dedicated Keycloak clusters across geographic regions delivers tangible benefits: reduced authentication response times, simplified management overhead, regional capacity scaling based on local demand patterns, and contained failure domains that preserve global service availability. Key implementation factors include careful hub location selection based on user distribution, reliable configuration synchronization between regional deployments, comprehensive performance monitoring frameworks, and robust automation pipelines to maintain consistency across the distributed architecture. This architecture enables effective adoption of Zero Trust security principles within global SASE infrastructure while balancing performance, manageability, and resilience requirements critical to enterprise deployments.
