What is digital sov­er­eign­ty?

Digital sov­er­eign­ty means retaining control over your data, systems and digital in­fra­struc­ture. For both in­di­vid­u­als and busi­ness­es, it is a key foun­da­tion for a secure, in­de­pen­dent and future-ready digital economy.

What does digital sov­er­eign­ty mean?

Digital sov­er­eign­ty describes the ability to use digital tech­nolo­gies and data in­de­pen­dent­ly, securely, and according to your own ob­jec­tives. It includes both technical and legal control over digital processes. Digital sov­er­eign­ty within a European context is closely tied to the goal of reducing de­pen­dence on large U.S. and Asian tech­nol­o­gy providers.

This means it goes beyond data security. It focuses on digital self-de­ter­mi­na­tion and the de­vel­op­ment of an in­de­pen­dent European IT in­fra­struc­ture. Companies should be able to decide where their data is stored, who can access it and how it is used. In the age of cloud computing and AI, sovereign data man­age­ment in the cloud plays a critical role in main­tain­ing control and trans­paren­cy. European cloud in­fra­struc­ture provides the foun­da­tion for that control and ul­ti­mate­ly for tech­no­log­i­cal in­de­pen­dence.

Why is digital sov­er­eign­ty important?

From a business per­spec­tive, companies that maintain digital sov­er­eign­ty remain flexible and able to act in­de­pen­dent­ly. By using open standards and in­ter­op­er­a­ble systems, they de­lib­er­ate­ly avoid lock-in effects. European cloud providers such as IONOS and solutions like Nextcloud Workspace offer viable al­ter­na­tives to many U.S. platforms. They provide trans­par­ent pricing and keep data pro­cess­ing within the EU. This strength­ens digital in­de­pen­dence, drives in­no­va­tion and boosts com­pet­i­tive­ness.

Legal re­quire­ments also play a central role. Com­pli­ance with European data pro­tec­tion laws, es­pe­cial­ly the GDPR, is an essential part of digital sov­er­eign­ty. Companies that store data with non-European providers may face legal un­cer­tain­ty. European cloud providers process data within the EU and follow European reg­u­la­tions. This allows companies to retain control over sensitive in­for­ma­tion while meeting com­pli­ance re­quire­ments.

Digital sov­er­eign­ty also strength­ens pro­tec­tion against cyber risks and unau­tho­rized access. Data stored on European servers is generally not subject to the US CLOUD Act or similar leg­is­la­tion that allows gov­ern­ment access to stored in­for­ma­tion. As a result, sovereign cloud in­fra­struc­ture improves security and trans­paren­cy. It provides certified security standards, encrypted com­mu­ni­ca­tion and clear vis­i­bil­i­ty into how data is stored and processed.

What legal frame­works support digital sov­er­eign­ty?

The European Union is strength­en­ing digital sov­er­eign­ty through ini­tia­tives such as GAIA-X, the EU Data Act and the NIS 2 Directive. These ini­tia­tives aim to establish common standards for data security, in­ter­op­er­abil­i­ty and cy­ber­se­cu­ri­ty. Their goal is to ensure that Europe’s digital in­fra­struc­ture can operate more in­de­pen­dent­ly. For companies, this creates clearer legal frame­works that combine strong data pro­tec­tion with tech­no­log­i­cal in­no­va­tion.

How can companies strength­en their digital sov­er­eign­ty?

A good starting point is to analyze your current IT and cloud landscape. Companies should clearly un­der­stand where their data is stored, which systems they rely on and who operates them. It is es­pe­cial­ly important to verify that all systems comply with European data pro­tec­tion re­quire­ments and meet GDPR standards.

The next step is to adopt open in­ter­faces and in­ter­op­er­a­ble systems. Open tech­nolo­gies reduce de­pen­dence on pro­pri­etary platforms and allow companies to retain full control over their data and processes. Providers with data centers in Europe should generally be preferred because they ensure data is processed within the EU, which minimizes legal risks.

Employee awareness is also essential. Regular data security training, along with clearly defined gov­er­nance and com­pli­ance policies, strength­ens digital sov­er­eign­ty within or­ga­ni­za­tions. Companies should also establish clear rules for storing, accessing and pro­cess­ing sensitive data.

What should companies look for in a European cloud provider?

When choosing a European cloud provider, consider the following criteria:

• Data storage in the EU: Ensure all data is stored in European data centers. This keeps pro­cess­ing within the EU and under European data pro­tec­tion laws.
• GDPR com­pli­ance: The provider should meet all re­quire­ments of General Data Pro­tec­tion Reg­u­la­tion. This ensures both personal data and company in­for­ma­tion are properly protected.
• Trans­paren­cy: The provider should be open about how data is handled, what security measures are in place, and what the contract terms look like. Trans­paren­cy helps you identify risks and maintain control over your data.
• In­ter­op­er­abil­i­ty: The systems you use should support open in­ter­faces and standard protocols. This allows you to switch between platforms or integrate new tools without becoming dependent on a single provider.
• Security cer­ti­fi­ca­tions: Look for providers with cer­ti­fi­ca­tions such as ISO 27001. These show that their security standards have been in­de­pen­dent­ly verified, and that your data is properly protected.

What does digital sov­er­eign­ty look like in practice?

Let’s look at an example of digital sov­er­eign­ty in practice. A mid-sized company decides to move its business-critical data to Nextcloud Workspace at IONOS. By using a European cloud provider rather than a US-based one, the company keeps full control over access rights, en­cryp­tion and data pro­cess­ing. All servers are also located within the EU.

The company also updates its internal processes so data can be exported or migrated between systems whenever necessary. Employees receive training on how to handle sensitive in­for­ma­tion securely. This approach strength­ens the company’s digital in­de­pen­dence and helps it meet GDPR re­quire­ments. Over time, it also makes the company more com­pet­i­tive in Europe’s digital economy.

Checklist: How digitally sovereign is your company?

Use this checklist to assess your digital sov­er­eign­ty:

✓ Do you know where your data is stored?

✓ Do you control who can access your data and how it is encrypted?

✓ Are your cloud services GDPR-compliant and hosted in the EU?

✓ Can you export or migrate your data at any time?

✓ Do you have a European con­trac­tu­al partner that is not subject to U.S. laws?

If you can answer “yes” to these questions, you are well on your way to achieving true digital sov­er­eign­ty and greater control over your digital in­fra­struc­ture.
