IdentityServer Containerized SSO

Overview

Implemented a comprehensive Single Sign-On (SSO) solution using IdentityServer4, providing centralized authentication and authorization for a complex enterprise ecosystem with zero-trust security principles.

The Challenge

The enterprise had 12+ disparate applications with inconsistent authentication mechanisms, leading to security vulnerabilities, poor user experience, and administrative overhead.

The Solution

Architected a containerized IdentityServer4 solution with Kubernetes orchestration, implementing OAuth2/OIDC protocols with zero-trust policies and seamless user experience across all applications.
