TL;DR: Cloud migration has made data residency and sovereignty harder to reason about because physical storage location, legal jurisdiction, and access control no longer line up cleanly, according to IS Decisions. The governance problem is not just where data sits, but who can access the keys, the sessions, and the files once control leaves the perimeter.
Editorial analysis by NHI Mgmt Group, based on content published by IS Decisions: “On-premise networks and data sovereignty: What you need to know in 2026”.
Key questions
Q: Who should own remediation when identity sprawl spans cloud and on-premises systems?
A: Ownership should sit with the programme that can reconcile inventory, entitlement data, and business purpose across environments, usually the IAM or identity governance team with security leadership backing.
Q: Why do data residency requirements matter more in cloud and SaaS environments?
A: Because the same record can exist in multiple locations at once, including replicas, backups, and analytics pipelines.
Q: What breaks when organisations treat on-premises storage as automatically sovereign?
A: They can miss third-party access, remote administration, and unmonitored file activity.
Practitioner guidance
- Separate residency from sovereignty in policy Document where data is stored, which laws apply, who administers the environment, and who can actually access the data.
- Govern encryption keys as part of sovereignty Inventory who controls keys for data at rest and how key access is delegated across cloud, SaaS, and on-prem environments.
- Extend MFA and contextual access to cloud services Anchor authentication in your existing identity system while enforcing conditional access for SaaS and remote access paths.
Bottom line: Cloud residency and sovereignty are no longer solved by knowing where data is hosted, because control over access, keys, and sessions now defines the real boundary.

Sovereignty without access governance is an assumption, not a control. The article shows that data residency only tells you where storage sits, while sovereignty depends on who can access the data and who controls the keys. That distinction matters because cloud architecture separates storage, administration, and usage into different control planes. Practitioners should stop treating sovereignty as a location decision and start treating it as a governed access state.
A question worth separating out:
Q: How should IAM teams handle data residency requirements in a regional deployment?
A: Start by classifying which identity records, logs, and device data are subject to residency rules, then map each to the region where it must be stored or processed. The key control is governance consistency: regional hosting only helps if administration, logging, retention, and offboarding remain aligned with the same policy baseline across every tenant.
