Data Sovereignty by Design: Five Practical Evaluation Lenses for IT Leaders

Summary

Data sovereignty is a market expression, not a universal legal standard, and IT leaders should evaluate it through architecture and governance questions rather than a single label. The assessment covers where data resides, who can access it, how it moves, and whether control is retained, with considerations varying by jurisdiction, industry, and risk posture. Physical location is only one part of a broader control boundary that includes operations, key custody, and access paths. The article proposes five technical lenses for evaluation: jurisdiction-native data placement, in-use encryption, customer-held keys, network isolation and identity-based access, and forensic-grade audit evidence. These lenses are practical reference points for architecture decisions, not a legal test or certification checklist, and organizations should assess their own requirements with qualified counsel.
