CHEZ PL: A Scalable Zero-Trust CIAM-PAM Architecture for Large Enterprises

Abstract

The CHEZ PL architecture introduces a revolutionary approach to enterprise identity management by integrating Customer Identity and Access Management (CIAM) and Privileged Access Management (PAM) within a cohesive zero-trust framework. Traditional security perimeters have proven increasingly inadequate against sophisticated identity-based threats, with organizations struggling to maintain consistent security across fragmented identity ecosystems. CHEZ PL addresses these challenges through a microservice-based infrastructure that delivers federated identity management, passwordless authentication, adaptive multi-factor authentication, and fine-grained authorization through distributed policy enforcement points. This architecture substantially reduces breach risks, decreases detection times, and minimizes unauthorized access incidents while improving operational metrics such as authentication completion rates and system availability. The framework's distributed design enables horizontal scaling to handle authentication volumes typical of large enterprises while maintaining performance under load. Additionally, the architecture incorporates comprehensive audit capabilities and data minimization principles that facilitate compliance with global regulatory requirements. CHEZ PL demonstrates significant advantages over traditional approaches across security effectiveness, operational efficiency, and user experience metrics, providing a scalable foundation for enterprise identity governance that adapts to evolving threat landscapes and business requirements.
