Digital sovereignty has moved from political speeches into boardrooms and factory planning. The question behind it is simple: who controls the data, software and infrastructure a company or a country depends on, and what happens if that control is lost? For Europe, the debate is about dependence on a small number of non-European tech giants, about national security and about resilient supply chains for chips and digital infrastructure. For manufacturers, it is about being able to choose, combine and replace technology without losing their data or their freedom of action.
- What it is: the ability of states, companies and individuals to make their own decisions in the digital world
- Main components: data, technological, infrastructure and regulatory sovereignty, plus the skills to use them
- Not the same as: autarky: it means having real choices, not doing everything alone
- EU context: the EU Data Act, Gaia‑X and the European data spaces
- In manufacturing: open standards and interoperable interfaces that prevent vendor lock-in
What is the meaning of digital sovereignty?
Digital sovereignty describes the capacity to act independently and self-determined in the digital space. It does not mean doing everything alone or banning foreign technology. It means having real choices: understanding the technologies you use, being able to switch providers, keeping control over your data and setting the rules that apply to it. It is often described as digital self-determination. Related terms are technological sovereignty, which focuses on the ability to develop key technologies, and cyber sovereignty, which some states use to describe control over national networks.
What are the main components of digital sovereignty?
- Data sovereignty: control over who accesses data and how it is used
- Technological sovereignty: the ability to develop, understand and choose key digital technologies
- Infrastructure sovereignty: control over the digital infrastructure, for example cloud and networks, including where data is stored
- Regulatory sovereignty: the ability to set and enforce rules for the digital space
- Skills: people who can build, operate and evaluate digital systems
How do digital sovereignty and data sovereignty differ?
Data sovereignty is one part of digital sovereignty. It means that the owner of data decides who may use it, for which purpose and under which conditions, and can verify that these conditions are kept. Digital sovereignty is broader and also covers the software, hardware, cloud services and know-how needed to act independently. A company can control its data contractually and still depend on a single cloud provider for everything else.
Why is digital sovereignty important for Europe?
The European Union has made Europe’s digital sovereignty a strategic goal for a competitive and sovereign Europe. Its digital strategy, and the policy framework behind it, combines regulation and investment. The General Data Protection Regulation sets rules for personal data. The Digital Markets Act limits the power of large platforms, and the Digital Services Act regulates online services. The Data Governance Act and the EU Data Act create rules for data sharing, and the Chips Act aims to strengthen European semiconductor production. Initiatives such as Gaia‑X and the common European data spaces build the infrastructure for trusted data sharing. Sovereign cloud offerings, operated under European law and control, respond to the same concern from the cloud service market. Cloud sovereignty has become one of the most discussed aspects of digital sovereignty in the European digital ecosystem.
Digital sovereignty in industry
For manufacturers, digital sovereignty is not abstract. A plant that depends on one vendor’s platform for its machine data cannot freely choose analytics tools, service partners or new suppliers. A machine builder whose products only speak a proprietary language makes its customers dependent and limits its own market. Industrial digital sovereignty therefore rests on a few practical principles:
- Open standards such as the Asset Administration Shell, OPC UA and MQTT, so data can move between systems
- Interoperability between products from different vendors
- Open source where it reduces dependency on single providers
- Data sovereignty in data sharing, with usage rules the data owner controls
- Exit options: the ability to replace a component without rebuilding the whole system, the opposite of vendor lock-in
These principles are part of the values the Open Industry 4.0 Alliance stands for: interoperability, vendor neutrality, open standards and digital sovereignty, tested in practice. In Factory‑X, OI4 helped build a data ecosystem in which companies share production data without losing control over it. In the Digital Product Passport project, members designed infrastructure concepts that keep data ownership and sovereignty with the companies. And the multi-vendor stack of the software-defined automation projects shows that control software does not have to be tied to one hardware vendor.
Frequently asked questions
What is data sovereignty in simple terms?
Data sovereignty means that you decide who may use your data, for what and under which conditions, and that you can check whether these rules are kept.
Does digital sovereignty mean using only European technology?
No. Digital sovereignty is about having choices and control, not about isolation. Open standards and interoperable products allow companies to use technology from anywhere without becoming dependent on it.
What is a sovereign cloud?
A sovereign cloud is a cloud service designed to keep data, operations and legal control within a specific jurisdiction, for example the EU, so that customers are not subject to foreign access laws or to a single provider’s terms.
