Europe is moving digital sovereignty from a broad policy principle toward a framework for assessing cloud and AI services and a procurement model for public-sector use. For CIOs, the practical question is not whether a provider is “sovereign” in the abstract, but which controls each workload needs—and whether a service can meet them without sacrificing essential capability, resilience or a credible exit path.
What does digital sovereignty mean for CIOs?
The European Commission defines tech sovereignty as “Europe’s ability to act independently in the digital world by developing and controlling key technologies, data, and infrastructure, while reducing reliance on non-EU providers.” That is broader than keeping data in a European data centre: it encompasses control over technology, infrastructure, operations and dependencies as well as data.
The shift matters because sovereignty is becoming something institutions can assess and apply in procurement, rather than only a strategic aspiration. It does not make every non-European service unsuitable, nor does it establish that every European provider meets every organisation’s needs. CIOs should treat it as a set of workload-specific risks and controls.
What has Europe changed, and what remains a proposal?
On 3 June 2026, the Commission presented a technological sovereignty package spanning semiconductors, cloud and AI, open source, and energy-system digitalisation. The package includes the EU Open Source Strategy and a Strategic Roadmap for Digitalisation and AI in Energy, as well as two proposed laws: Chips Act 2.0 and the Cloud and AI Development Act (CADA). Presentation of the package is not adoption of those proposed laws.
#1 Best Overall
CADA proposes a common EU-wide way to assess cloud and AI sovereignty, paired with a mechanism to encourage public-sector adoption. Its stated aims also include research, development and innovation in cutting-edge sustainable cloud and AI, and building capacity by accelerating conditions for deploying EU data centres, including those needed for essential public functions.
The Commission’s cloud policy page describes a proposal aim to at least triple EU data-centre capacity within five to seven years, and to meet the needs of EU businesses and public administrations by 2035. These are targets, not evidence that the capacity has already been built or a guarantee that it will be delivered.
How the Commission is making sovereignty measurable
The Commission’s Cloud Sovereignty Framework combines an overall score based on 48 criteria with Sovereignty Effectiveness Assurance Levels (SEAL). The criteria are grouped into eight categories: strategic, legal and jurisdictional, data and AI, operational, supply-chain, technological, security and compliance, and environmental sustainability. The Commission associates SEAL-2 with data sovereignty, SEAL-3 with technological autonomy, and SEAL-4 with full sovereignty.

Those levels are useful as a structured assessment, not a universal guarantee. A CIO still needs to establish what a rating covers, which service and operating arrangement it applies to, and whether its controls address the organisation’s own legal obligations and threat model. A broad label cannot substitute for checking contract terms, privileged access, dependencies and service capabilities.
What the Commission’s cloud procurement shows
The Commission says its sovereign-cloud call lets Union entities procure services with a maximum value of EUR 180 million over six years. It selected four contracts to diversify provision and reduce lock-in risk. The Commission’s reported SEAL results apply to these awards; they are not a market-wide provider ranking.
| Selected provider or consortium | Commission-reported SEAL level | What the Commission says about the award |
|---|---|---|
| Luxembourgish-French partnership led by Post Telecom, with OVHcloud and CleverCloud | SEAL-3 | Selected for the Union-entity procurement. |
| STACKIT (Germany) | SEAL-3 | Selected for the Union-entity procurement. |
| Scaleway (France) | SEAL-3 | Selected for the Union-entity procurement. |
| Belgian-French-Luxembourgish partnership led by Proximus, using services from S3NS, Clarence and Mistral | SEAL-2 | The Commission says the service includes a Google Cloud technology base operated exclusively by EU companies. |
The awards illustrate that the Commission considered multiple dimensions, including strategic, legal, operational, environmental, supply-chain, technology, security and compliance factors. It also considered service capability. A CIO comparing providers should therefore assess whether the service offers the managed capabilities, developer experience, automation and performance the workload requires alongside its sovereignty evidence.

How to assess a workload before choosing a cloud
Start with the workload, not the provider’s marketing category. Record what the system does, what harm an outage or disclosure could cause, what rules apply, and which controls are necessary. Then compare candidates against the same requirements.
- Classify sensitivity and criticality. Identify regulated, safety-critical, national-infrastructure and commercially sensitive workloads. Set the consequences of disclosure, disruption or loss of control before deciding what level of assurance is proportionate.
- Map legal and jurisdictional exposure. Establish which entities control the provider and its relevant affiliates, where contractual responsibility sits, and which authorities could compel access under applicable law. A European hosting location answers only part of that question.
- Verify operational control. Ask who administers systems, holds privileged credentials, approves support access and can keep services running during a disruption. Confirm how those controls are evidenced and enforced in the actual service arrangement.
- Trace technology and supply-chain dependencies. Identify important software, infrastructure, support and subcontractor dependencies. Assess whether a third party could interrupt service, constrain changes or limit access to updates and expertise.
- Demand workload-appropriate security, compliance and sustainability evidence. Match the evidence to the data and operating risks in scope. A general assurance statement is not equivalent to evidence for the specific workload, configuration or contract.
- Test service fit as well as sovereignty. Compare required managed services, automation, developer experience and performance. A control profile that cannot support the application’s operational needs is not a workable design.
- Make portability and exit concrete. Define data formats, contract rights, migration responsibilities, timelines and dependencies, then test the plan. The Data Act seeks fast, free and technologically fluid cloud switching, interoperability and safeguards for international transfers; those policy aims do not make a real migration effortless.
Does hosting data in Europe protect it from foreign laws?
Not by itself. Location is relevant, but it does not alone establish who controls a provider, who can administer a service, what laws may apply to the provider, or how an access demand would be handled. Evaluate the corporate and contractual structure, access controls, operating model and applicable law for the particular service. Avoid turning a data-centre address into a categorical claim about legal exposure.

Is a sovereign cloud really sovereign?
“Sovereign” is not a yes-or-no property that follows automatically from European ownership, European staff or European hosting. The Commission framework offers criteria and SEAL levels to distinguish dimensions of control. In its procurement account, the Proximus-led award reached SEAL-2 despite using a Google Cloud technology base, which the Commission says is operated exclusively by EU companies. That is an example of an assessed arrangement, not proof that the underlying technology has no dependencies or that the same result applies to other services.
Gaia-X is also not a cloud provider. A 26 November 2025 IT Pro feature describes it as a rules and trust-framework initiative involving identity, compliance automation, service labelling, policy enforcement and interoperability. In that report, Airbus chairwoman of the Gaia-X Board and EVP Digital Catherine Jestin described a workload distinction: “I really love to work with AWS, with Google and Microsoft… but not for the most critical applications and services.” Her comment illustrates that using a hyperscaler for some workloads can coexist with reserving stricter requirements for the most critical ones.
Should you move critical workloads to a European cloud?
Consider a move when the workload’s legal, operational or supply-chain exposure cannot be acceptably controlled in its current arrangement, and a candidate service can meet the workload’s technical and operational requirements with verifiable controls. Do not migrate solely to satisfy a broad label or assume that a European provider automatically eliminates dependencies. The Commission’s procurement and framework support a more precise decision: segment workloads, set required controls, compare evidence and service fit, and plan a practicable exit.
