The conversation around digital sovereignty has moved from academic to urgent. What was once a niche concern for government agencies is now a board-level issue for enterprises, public sector organisations, and scale-ups across Europe.
Here is why, and what it means for your cloud strategy.
The legal landscape has shifted#
The Data Privacy Framework: a framework still under scrutiny#
In July 2023, the European Commission adopted the EU-US Data Privacy Framework (DPF), replacing the Privacy Shield that was invalidated by Schrems II in 2020. This framework currently allows organisations to transfer data to US providers.
But even with the DPF in place, several structural concerns still matter:
- FISA Section 702 still allows US intelligence agencies to compel US companies to hand over foreign users’ data, without a warrant, without notification
- The CLOUD Act still grants US authorities access to data held by US companies regardless of where it’s stored geographically
- Limited judicial redress — the new “Data Protection Review Court” remains disputed by many critics, who question whether it provides the remedies EU law requires
Many legal observers expect further challenge. The framework rests on executive orders that a future US administration could revoke, which is why some organisations are reassessing how much critical exposure they want tied to it.
Geopolitical risk is real#
Beyond the legal technicalities, the geopolitical landscape has fundamentally changed:
- Increasing US-EU tensions on trade, tariffs, and technology policy
- Sanctions and export controls that can be applied unpredictably
- The precedent of sudden service restrictions based on political decisions
Relying entirely on US infrastructure means accepting that parts of your business continuity and compliance model are linked to political stability between Washington and Brussels. For some critical operations, many organisations will judge that risk too high.
GDPR enforcement is intensifying#
We’re past the grace period. Regulators are issuing record fines:
- Meta: €1.2 billion (May 2023) for EU-US data transfers
- Amazon: €746 million (2021) for processing personal data
- Google: Multiple fines totalling hundreds of millions
More importantly, the pattern of enforcement is expanding beyond tech giants to enterprises across sectors.
NIS2 raises the bar#
The NIS2 Directive, effective October 2024, significantly expands cybersecurity requirements:
- More sectors covered (healthcare, waste management, food production, etc.)
- Personal liability for management
- Stricter incident reporting (24-hour notification)
- Supply chain security requirements
US cloud providers aren’t automatically disqualified, but the compliance burden for using them has increased substantially.
Beyond compliance: strategic considerations#
Customer trust#
Your customers are paying attention. B2B buyers increasingly include data residency questions in procurement processes. B2C customers are becoming more aware of where their data lives.
“Data stored in EU” is becoming a competitive differentiator.
Operational certainty#
Regulatory uncertainty creates operational risk. If a future court ruling or regulatory action restricts US cloud services, organisations heavily dependent on hyperscalers face:
- Emergency migration projects
- Service disruptions
- Potential fines for non-compliance during transition
Moving some or all critical workloads to EU-sovereign infrastructure can reduce this exposure materially.
What “EU sovereignty” actually means#
Not all EU-based cloud services are equal. True sovereignty requires:
Data residency#
Data stored exclusively in EU data centres. This is the baseline requirement.
Legal jurisdiction#
The entity controlling the data is subject to EU law, not US, Chinese, or other foreign jurisdiction. This means EU-owned or a legal structure that insulates from foreign government access.
Operational control#
EU persons and entities control the infrastructure operations. No remote access from non-EU locations to administrative systems.
Technology independence#
For the most sensitive use cases: no hardware or software components that create backdoor access, ability to verify the full technology stack.
T Cloud: hyperscaler capabilities, EU sovereignty#
The market for EU-sovereign cloud has matured. T Cloud, Deutsche Telekom’s sovereign cloud platform, now offers the service breadth and operating model most enterprises expect from hyperscalers:
- Enterprise-grade infrastructure with the scale and reliability you expect
- AI and machine learning capabilities operated entirely from German data centres
- Complete tooling ecosystem — the same developer experience, CI/CD pipelines, and operational workflows you’re used to
- 24/7 EU-based support with operations and support centred in the EU
This isn’t a compromise. It’s a credible enterprise cloud platform under EU jurisdiction.
The path forward#
Shifting critical workloads into EU-sovereign infrastructure doesn’t mean a risky big-bang migration or starting from scratch. A pragmatic, proven approach:
- Design — Start with architecture, exploration, and transformation planning tailored to your business and compliance requirements
- Build — Platform engineering, landing zones, shared services, and cloud-native application platforms, fully built and production-ready
- Protect — Zero-trust security, sovereign identity, compliance as code, and continuous governance
- Operate — Centralised monitoring, backup, disaster recovery, and cost management from day one
- Migrate — Assess existing workloads, modernise where needed, and execute the migration systematically
- Enable — Phased knowledge transfer and paired operations until your team has full ownership
The goal is an EU-sovereign target state for the workloads that need it most, delivered at a pace that works for your organisation, without disrupting your business.
