Securing Europe’s Digital Future: The Drive for Tech Sovereignty
Europe’s strategic ambition of tech sovereignty seeks to ensure control over critical digital infrastructure, data, and platforms. Driven by geopolitical uncertainty, regulatory gaps in U.S. data control frameworks like the CLOUD Act, and dominance of U.S. hyperscalers, the EU is prioritising investments, partnerships, and policy structures to reclaim its technological independence, European DIGITAL SME Alliance+5European Parliament+5TechRadar+5.
This post examines the scope of Europe’s strategy, key initiatives like EuroStack and Gaia‑X, the rise of regional players, and roadmaps to long term resilience.
1. Why Digital Sovereignty Matters
Over 69% of Europe’s cloud market is controlled by U.S. firms such as AWS, Azure, and Google Cloud, with only about 13% by European providers posing legal exposure under U.S. extraterritorial laws like FISA and the CLOUD Act.. Nextcloud+4Inside Telecom+4Wikipedia+4European Parliament.
The Schrems II ruling underscored Europe’s distrust of U.S. standards, catalysing the urgency for truly sovereign infrastructure.
Political volatility particularly under recent U.S. administrations has amplified risks, prompting lawmakers and enterprises across member states to seek digital autonomy, Financial TimesBusiness Insider.
2. Key Pillars of the Strategy
EuroStack: Building the European Technological Stack
EuroStack is a €300 billion vision to construct a sovereign stack encompassing semiconductor manufacturing, AI frameworks, cloud platforms, digital identity, and public service, Reuters+15European DIGITAL SME Alliance+15Financial Times+15.
Public procurement reform is central through mechanisms like a “Buy European Tech Act” to ensure public contracts prioritise EU-native providers.Inside Telecom+1Financial Times+1.
Gaia‑X & the Super Cloud Continuum
Gaia‑X, launched in 2019 by Germany and France, is an EU backed federated data infrastructure aiming to give users control over data access, while ensuring transparency and interoperability across cloud services michaelwaterman.nl+3Wikipedia+3Inside Telecom+3.
Under the IPCEI “8ra” initiative, about 150 partners including SAP, Siemens, Airbus, Telefónica are building a pan-European cloud edge continuum targeting up to 10,000 edge‑cloud nodes by 2030 t-systems.com.
DNS4EU: Sovereign Domain Name Resolution
Launched in June 2025, DNS4EU offers an EU based, privacy-first DNS resolver service, free for public use. Operated by a multi country consortium, it reinforces sovereignty over critical infrastructure layers and ensures compliance with GDPR and NIS2.
3. Private Sector and Market Response
Despite regulatory efforts, over 70% of European businesses still rely on U.S. cloud providers. However, 72% now cite data control as a top priority when choosing vendors, TechRadar+1AInvest+1.
European cloud firms such as OVHcloud, Elastx, Scaleway, Exoscale, and Nextcloud are gaining traction as sovereign alternatives, TechRadar+2AInvest+2Cybernews+2.
A landmark agreement between CISPE (Cloud Infrastructure Services Providers in Europe) and Microsoft now allows European providers to offer Microsoft software independently and on more competitive terms a step toward operational sovereignty, TechRadar+1IT Pro+1.
Meanwhile, hyperscalers like Microsoft are adapting: expanding their European footprint by 40% across 16 countries, pledging legal protections via a “European cloud” board, staking infrastructure in Switzerland, and committing to the EU Data Boundary project to limit non EU access to European customer data. a InfoQ+1AP News+1.
4. Policy, Regulation, and Investment Framework

Key legislation includes the AI Act (effective 2024), Digital Markets Act, Data Act (effective late 2025), the Chips Act, CADDA, and Energy Efficiency Directive, all aligned to strengthen sovereignty, interoperability, and sustainability in digital infrastructure cascadeadvisory.co+1AInvest+1.
EuroHPC, with a €7 billion budget, is establishing AI data centre “gigafactories” across multiple member states, complemented by the InvestAI fund (€200 billion overall, including €20 billion specifically for infrastructure investment) announced in early 2025, Wikipedia+1cascadeadvisory.co+1.
5. Challenges and the Path Forward
Achieving true digital sovereignty requires more than localised data it demands capabilities spanning hardware, software, AI infrastructure, and open networks.
Europe’s existing shortfall in scale, fragmented regulation, and funding disparity with the U.S. and China pose ongoing barriers.
Progress hinges on empowering SMEs, reforming procurement policies, and building public-private partnerships rather than mere regulation or subsidies alone. TechRadarEuropean DIGITAL SME Alliance.
Finally, balancing collaboration with global players (e.g., Microsoft, Nvidia) and supporting truly independent European infrastructure is critical to avoid “sovereignty washing”, Financial Times.
Conclusion
Europe’s push for tech sovereignty is a comprehensive, long-term endeavour. Anchored in legislation, strategic investment, and collaborative infrastructure projects, it aims to reduce reliance on foreign platforms and enable European innovation to flourish. Whether it’s through Gaia‑X, EuroStack, DNS4EU, or European cloud providers, the path toward digital independence is underway.
For organisations and policymakers, the focus must shift from mere compliance to strategic sovereignty: building resilient systems, supporting native providers, and embedding control at every layer of the digital stack.
