This white paper discusses the evolving concept of data sovereignty, emphasizing the importance of control over mere location in the context of data management and compliance. It outlines how enterprises must navigate a landscape where data flows across regions and platforms, highlighting the inadequacies of traditional location-based sovereignty approaches. The document identifies critical trends affecting data sovereignty, including global operating models, platform concentration, and regulatory fragmentation. It presents a framework for redefining data sovereignty through three key capabilities: control, enforcement, and proof. Control involves establishing clear ownership and usage rights, while enforcement focuses on applying sovereignty rules consistently across systems. Proof entails demonstrating compliance through audit trails and data lineage. The paper argues that organizations must integrate sovereignty into their architectural design rather than treating it as an afterthought, thereby positioning themselves to adapt to regulatory changes and leverage advanced analytics and AI safely.
