Schrems III: Preparing for the Next Data Transfer Challenge
The EU-US Data Privacy Framework (DPF), adopted in July 2023, was supposed to provide a stable legal basis for transatlantic data transfers. Yet legal scholars and privacy advocates have long predicted its vulnerability to challenge, and in 2026, that challenge is materialising.
The Pattern
The history is instructive:
- Safe Harbor (2000–2015): Invalidated by Schrems I due to inadequate US surveillance protections
- Privacy Shield (2016–2020): Invalidated by Schrems II for essentially the same reasons
- Data Privacy Framework (2023–?): Built on Executive Order 14086, which can be modified or revoked by any future US administration
Why Schrems III Is Coming
The fundamental tension remains unresolved. US surveillance law (particularly Section 702 of FISA) grants broad data collection powers that many EU legal experts consider incompatible with EU fundamental rights. The DPF's reliance on an executive order, rather than legislative reform, means its protections can be revoked overnight.
How to Prepare
Assess Your Exposure
Catalogue every data flow that relies on the DPF. Prioritise by:
- Volume and sensitivity of data transferred
- Criticality of the service to business operations
- Availability of EU-based alternatives
Develop Contingency Plans
For each critical service, identify:
- EU-based alternative providers
- Migration timelines and complexity
- Interim measures (encryption, pseudonymisation)
Implement Technical Safeguards
Regardless of legal frameworks:
- Use end-to-end encryption where possible
- Implement data pseudonymisation for analytics
- Maintain EU-based backup copies of critical data
Diversify Your Stack
The most resilient strategy is to reduce dependency on any single jurisdiction. A predominantly EU-based stack with selective, well-managed transatlantic flows minimises disruption from legal framework changes.
The Strategic Advantage
Organisations that proactively build sovereign European infrastructure won't just survive Schrems III. They'll thrive while competitors scramble to adapt.
