A Security Framework for Multi-Tenant PEO Applications in Cloud Environments

Abstract

This paper presents a comprehensive security framework tailored for multi-tenant Professional Employer Organization (PEO) applications hosted in cloud environments. Multi-tenancy in cloud-based PEOs introduces complexities related to data isolation, identity management, compliance, and threat detection. Our proposed framework integrates Zero Trust principles, tenant-aware identity federation, and AI-driven threat modeling to address these challenges. Through simulations and case studies, we demonstrate the framework’s ability to improve security posture while maintaining performance and scalability across cloud platforms. The study concludes with implications for future cloud-native PEO systems and recommendations for implementation.
