Digital Sovereignty for Enterprises: Cloud, AI, and Data Control in Europe

"Our data is on AWS" – a sentence that will raise more questions in the future. The EU is pushing digital sovereignty, and companies need to position themselves.

What does this mean concretely? What decisions are pending? And how do you find the balance between innovation and independence?

What Is Digital Sovereignty?

Digital sovereignty means:

1. Control over your own data – Where is it, who has access?
2. Technological independence – No critical dependency on single vendors
3. Legal certainty – Which law applies to my data?
4. Strategic capability – Can we switch if needed?

Why Now?

Political drivers:

• EU Data Act in effect
• AI Act with transparency requirements
• CLOUD Act conflict (US authority access to EU data)
• Geopolitical tensions

Economic drivers:

• Rising cloud costs
• Vendor lock-in becomes expensive
• Customers ask about data locations
• Tenders require EU hosting

The Dimensions of Digital Sovereignty

Dimension 1: Cloud Infrastructure

Current reality:

• ~70% of EU cloud market with US hyperscalers
• AWS, Azure, Google dominate
• Few European alternatives at enterprise scale

Options for companies:

Recommendation by use case:

Dimension 2: Software & SaaS

The problem:

• Microsoft 365, Google Workspace, Salesforce – all US-based
• Alternatives exist but often less convenient
• Switching costs are high

Alternatives landscape:

Pragmatic approach:

1. Identify critical data
2. For critical areas: Evaluate EU solutions
3. For less critical: US solutions with additional measures
4. Document exit strategies

Dimension 3: AI & Data

Special challenge:

• ChatGPT, Claude, Gemini – all US-based
• Training data question: Does my data flow into training?
• Inference in US data centers
• No fully sovereign enterprise LLMs

Options:

Recommendation:

1. For general use: Enterprise versions with opt-out
2. For sensitive data: EU-hosted solutions
3. For critical applications: Open source or on-premise

Dimension 4: Network & Connectivity

Often overlooked:

• Internet routing frequently through US
• DNS predominantly US-controlled
• CDNs (Cloudflare, Akamai) US-based

Measures:

1. Evaluate EU CDNs (Bunny.net)
2. DNS redundancy with EU providers
3. Direct peerings where possible
4. Check routing policies

GAIA-X: The European Approach

What Is GAIA-X?

GAIA-X is an initiative for a federated, sovereign data ecosystem:

• Common standards and rules
• Interoperability between providers
• Transparency about data processing
• European values

Current Status

Positive:

• Framework for data sovereignty
• Growing ecosystem
• Industry-specific data spaces (Catena-X for automotive)

Challenge:

• Complex governance
• Slow implementation
• Few concrete products for SMBs yet

Relevance for Companies

Relevant now:

• Automotive (Catena-X)
• Healthcare
• Public sector

Future relevance:

• All industries with data exchange needs
• Companies with public contracts
• Regulated industries

Practical Implementation: The Sovereignty Roadmap

Phase 1: Assessment (Month 1)

Create data inventory:

Document dependencies:

• Which vendors are irreplaceable?
• What happens if a vendor fails?
• How expensive would a switch be?

Phase 2: Strategy (Month 2)

Classification:

Create roadmap:

1. Identify quick wins
2. Plan medium to long-term measures
3. Allocate budget
4. Clarify responsibilities

Phase 3: Quick Wins (Month 3-4)

Immediately implementable:

1. Activate training opt-outs (ChatGPT Enterprise, etc.)
2. Review and renegotiate DPAs
3. Backup strategy for critical SaaS
4. Data location documentation for customers/audits
5. Password manager to EU solution (Bitwarden EU)

Phase 4: Structural Changes (Month 5-12)

Medium-term measures:

1. Email migration (if desired)

   • Exchange Online → Mailbox.org or Proton Business

2. Cloud diversification

   • Critical workloads on EU providers
   • Multi-cloud architecture

3. Adjust AI strategy

   • EU LLMs for sensitive applications
   • Open source for on-premise needs

4. Document exit strategies

   • For every critical vendor
   • Including data export processes

Cost-Benefit Analysis

Typical Additional Costs

Quantify Benefits

Direct benefits:

• Compliance with EU regulation (avoid fines)
• Reduced vendor lock-in risk
• Negotiating power in contracts

Indirect benefits:

• Customer preference for EU providers
• Public contracts (often EU hosting required)
• Reputation protection
• Lower geopolitical risks

Industry-Specific Requirements

Financial Services

• BaFin requirements for outsourcing
• DORA (Digital Operational Resilience Act)
• Often: On-premise or dedicated infrastructure

Healthcare

• Special protection requirements (Art. 9 GDPR)
• Gematik requirements
• Tendency toward German providers

Public Sector

• Procurement law favors EU providers
• BSI requirements
• Increasingly: Open source preference

Industry/Manufacturing

• Catena-X for automotive
• Protect trade secrets
• Consider OT/IT convergence

Checklist: Digital Sovereignty

Immediately

• Create data inventory
• Document vendor locations
• Activate training opt-outs
• Check DPAs

Short-term (3 months)

• Classify critical data
• Document exit strategies
• Evaluate EU alternatives
• Create roadmap

Medium-term (12 months)

• Implement quick wins
• Pilots with EU providers
• Develop multi-cloud strategy
• Implement AI governance

Long-term

• Structural migration where sensible
• Regular reviews
• Regulatory monitoring
• Share best practices

Conclusion

Digital sovereignty is not all-or-nothing. It's a spectrum on which every company must position itself.

The three most important steps:

1. Know what you have – Data, dependencies, risks
2. Prioritize – Not everything is equally critical
3. Act pragmatically – Quick wins first, plan strategic measures

EU regulation will continue to increase. Those who start today have an advantage.
