The acceleration of cloud transformation has brought SAP Business Technology Platform (SAP BTP) to the center of intelligent enterprise architectures. As organizations expand hybrid landscapes integrating SAP S/4HANA, cloud extensions, APIs, and third-party systems, traditional perimeter-based security models have become insufficient [3]. This paper presents comprehensive security architecture grounded in Zero-Trust principles, continuous verification, identity centric security, least privilege design, and micro segmentation, aligned with industry standards defined by NIST and adapted for SAP BTP’s multi-tenant environment. The study evaluates identity governance using SAP Cloud Identity Services, secure integration patterns for SAP CPI, and AI-driven threat detection mechanisms. Through comparative assessments and real-world architectural patterns, this work demonstrates that Zero-Trust adoption significantly enhances confidentiality, integrity, audit readiness, and resilience across SAP BTP ecosystems [5], [10].
