Hook: Why hosting applicant data in the EU matters to HR and legal teams in 2026
Employers hiring international talent face a double bind: the need to move quickly to secure candidates, and ever-tightening rules about where and how personally identifiable information (PII) — including sensitive immigration records — may be stored and accessed. In January 2026, AWS launched the AWS European Sovereign Cloud, a region designed to address EU sovereignty concerns by physically and logically separating infrastructure and inserting contractual and technical safeguards. But is a sovereign cloud required for your immigration applicant data? And if so, how do you migrate without creating more compliance risk?
Quick answer (inverted pyramid): When to consider a sovereign cloud — and what to do first
Short version: If you process EU applicant data that includes sensitive immigration records (biometrics, criminal checks, medical or ethnicity information), if national laws in specific member states require local storage or restrict cross-border transfers, or if your organisation is subject to high-risk regulatory oversight, you should strongly consider a sovereign cloud. For most employers, the decision should be based on a documented risk assessment (DPIA), data mapping and contractual review — not marketing alone.
Top-line checklist (start here)
- Perform a targeted Data Mapping for all immigration and applicant data.
- Run a DPIA focused on cross-border transfer risk and special category data.
- Review local laws in key jurisdictions for data residency mandates.
- Evaluate the sovereign cloud provider’s technical, legal and contractual assurances.
- Plan a staged migration with encryption, key custody strategy (BYOK/HYOK), and rollback testing.
