The hidden costs of open source SSO: Why enterprise readiness requires more than free code

Single Sign-On (SSO) systems are crucial components of an organization's infrastructure, controlling access to data and maintaining security, but opting for open-source SSO solutions like Keycloak, Gluu, or Authelia presents significant challenges as companies scale. While these open-source options offer transparency, control, and initial cost benefits, they require organizations to assume full responsibility for operational, security, and compliance burdens, transforming them into their own identity operations teams. This involves managing uptime, security patches, integration complexities, and compliance requirements, which can be overwhelming and demanding. As the complexity of authentication increases with enterprise demands and customer base growth, open-source tools often lack the necessary infrastructure for reliable enterprise-level authentication. Commercial-grade platforms like WorkOS provide a viable solution by offering pre-built integrations, compliance with standards like SOC 2 and GDPR, and robust support, helping businesses maintain enterprise-grade security and reliability without the overhead of maintaining it in-house.
