Digital Sovereignty in 2026: A Plain-English Guide for EU Teams

Digital sovereignty means your company stays in control of its data, its tools and the laws that apply to them. For a European business in 2026, that comes down to three questions: where is our data stored, who can operate or switch off the software we rely on, and which country's courts can force a vendor to hand our data over?

That sounds like a topic for ministers and cloud architects. It isn't anymore. If your team chats in one app, signs contracts in another and keeps customer data in a third, you already have a sovereignty position. You just haven't written it down yet.

This guide covers what the term actually means, why it jumped from policy papers to board agendas, a ladder for figuring out how sovereign your stack really is, and a practical audit a 20 to 200 person company can run without hiring a lawyer for every line. We will also be honest about the trade-offs, because plenty of US software is very good and pretending otherwise helps nobody.

What digital sovereignty actually means

Strip away the conference talk and digital sovereignty is about control. Not ownership of servers, not patriotism, not a flag on a login screen. Control.

It breaks into three layers. Most confusion happens when people talk about one layer and assume they have covered all three.

Data control: where your data lives

This is the layer everyone starts with. Is your data stored in Frankfurt, Dublin, Oslo or Virginia? Can you pick the region? Are backups in the same place as the live data?

Data location matters, but it is the easiest layer to get right and the easiest to oversell. Data sitting in an EU data centre is a good start. It is not the finish line.

Operational control: who runs the thing

The second layer asks who operates the service day to day. Who has admin access to the infrastructure? Where is the support team that can read your tickets (and sometimes your data)? Who holds the encryption keys? Could someone outside your company suspend your account?

This layer stopped being theoretical in 2025. Heise reported that the chief prosecutor of the International Criminal Court lost access to his Microsoft email account after US sanctions, and that Microsoft president Brad Smith said the company had not ended or paused services to the court itself (Heise, 2025). Whatever the exact details, the lesson for every CIO was simple: a foreign policy decision can reach your inbox.

Legal control: whose courts can order disclosure

The third layer is the one that trips up most "EU hosted" claims. The question is not where the server is. It is which legal system can compel the company that runs it.

The US CLOUD Act, enacted in March 2018, lets US authorities obtain electronic evidence from US providers "wherever it happens to be located," according to the US Department of Justice. So a US company storing your data in Amsterdam can still receive a valid US order for it.

Put the three layers together and you get a working definition: you have digital sovereignty over a tool when you know where its data sits, who can operate or cut it off, and which courts can reach it, and you are comfortable with all three answers.

How digital sovereignty went from policy jargon to boardroom topic

For years this was a debate for privacy lawyers and a few stubborn IT directors. Then a string of court rulings, laws and very public admissions turned it into a procurement question. Here is the short version.

1. October 2015: Safe Harbor falls. The Court of Justice of the EU invalidated the first major EU-US data transfer arrangement in Schrems v. Data Protection Commissioner on 6 October 2015 (Harvard JOLT, 2015).
2. March 2018: the CLOUD Act. US law confirms that US providers can be compelled to hand over data stored abroad (US DOJ).
3. July 2020: Privacy Shield falls. In the Schrems II judgment (C-311/18) of 16 July 2020, the same court struck down Safe Harbor's replacement, while keeping standard contractual clauses alive with extra conditions (eucrim, 2020).
4. July 2023: the Data Privacy Framework. On 10 July 2023 the European Commission adopted a new adequacy decision for the EU-US Data Privacy Framework, backed by a new Data Protection Review Court for EU citizens (European Commission, 2023).
5. January 2025: the framework wobbles. On 27 January 2025 the US president removed all three Democratic members of the Privacy and Civil Liberties Oversight Board, leaving it without the quorum it needs to issue reports. The Commission's adequacy decision had relied partly on that board's oversight (Lawfare, 2025).
6. June 2025: the sentence heard round Europe. Asked under oath by a French Senate inquiry whether he could guarantee that French citizens' data would never be sent to US authorities without French agreement, Microsoft France's director of public and legal affairs, Anton Carniaux, answered: "No, I cannot guarantee that." He added that it had never happened (The Register, 2025).
7. September 2025: two things at once. The EU Data Act went into application on 12 September 2025 (European Commission). And on 3 September 2025 the EU General Court dismissed a challenge to the Data Privacy Framework (T-553/23). The challenger, French MP Philippe Latombe, appealed to the Court of Justice on 31 October 2025 (C-703/25 P), so the question is still open (Digital Policy Alert).

Count the score. Two transatlantic frameworks struck down in five years, a third one currently legal but under appeal. If you are a finance director, that is not a stable foundation for a ten year software decision. It is a foundation you plan around.

Governments started voting with their feet

The public sector moved first, partly because it had the most to lose.

• Denmark. The Danish Ministry of Digitalisation announced it would move from Microsoft Office 365 to LibreOffice, starting with roughly half its staff and aiming to end its dependence on Microsoft Office by the end of 2025. Copenhagen and Aarhus, the country's two biggest municipalities, announced plans to phase out Microsoft systems too (Computing, 2025).
• Schleswig-Holstein, Germany. About 30,000 state employees had moved off Microsoft products by mid 2025, with LibreOffice replacing Office and Open-Xchange replacing Outlook. The state's digital minister, Dirk Schroedter, put it bluntly: "We're done with Teams!" (TechRadar, 2025).
• The International Criminal Court. The court in The Hague plans to replace Microsoft software on about 1,800 workstations with openDesk, an open-source suite from Germany's Center for Digital Sovereignty, ZenDiS (Heise, 2025).

Brussels started drawing up the plans

On the policy side, a CEPS proposal called EuroStack argued for a European technology stack covering chips, cloud, data and AI, funded with roughly EUR 300 billion over a decade (CEPS, 2025). The European Commission also published a Cloud Sovereignty Framework, first presented in October 2025 and used to score cloud providers bidding for EU institution contracts (European Commission). We will borrow its best idea in a minute.

The numbers behind the worry

Opinions are cheap. Here is the market data.

Europe's cloud is mostly American

Synergy Research Group found that European cloud providers held just 15% of their own home market in 2024, down from 29% in 2017. Amazon, Microsoft and Google together held 70%. The biggest European players, SAP and Deutsche Telekom, had about 2% each (Synergy Research, 2025).

Do the math on that EUR 61 billion market size for 2024:

• European providers: 15% of EUR 61 billion is about EUR 9 billion.
• The US big three: 70% of EUR 61 billion is about EUR 43 billion.
• For every euro spent with a European cloud provider, Europeans spent nearly five with three American ones.

The awkward part: European providers more than tripled their revenue over that period and still lost share, because the market grew six times bigger and the giants grew faster.

Sovereign cloud spending is taking off

Gartner forecasts worldwide sovereign cloud infrastructure spending of USD 80 billion in 2026, up 35.6% from 2025. The European numbers are the eye-catching part (Gartner, 2026):

• Europe: USD 6.9 billion in 2025, rising to USD 12.6 billion in 2026, an 83% jump.
• Europe is forecast to reach USD 23.1 billion in 2027, overtaking North America.
• Gartner expects sovereign cloud spending to shift 20% of current workloads from global to local cloud providers.

That is not a niche. That is budget moving.

And almost every company is exposed

Eurostat data shows 52.7% of EU enterprises bought cloud computing services in 2025, rising to 84.7% of large companies. Of those cloud buyers, 85.2% used it for email and 71.7% for office software (Eurostat, 2026).

Multiply it out: 52.7% times 85.2% means roughly 45% of all EU enterprises run their email in someone else's cloud. Email is where contracts, invoices, CVs and customer complaints live. If you want one place to start your sovereignty thinking, it is probably your inbox.

The sovereignty ladder: six rungs for normal companies

The Commission's Cloud Sovereignty Framework scores providers from SEAL-0 (no sovereignty) to SEAL-4 (full digital sovereignty), and it has one rule worth stealing: a service's overall level is the lowest level it achieves across all objectives (European Commission). Your stack is only as sovereign as its weakest link.

That framework was built for government tenders. Here is a simplified version for a company that just wants to choose a chat tool without a 90 page procurement process.

1. Rung 0: US company, data in the US. The default for many tools. US law applies to everything. Fine for low-risk data, uncomfortable for HR records.
2. Rung 1: US company, EU data region. The vendor offers "EU data residency." Your data sits in Europe, but the operator is still a US company within reach of the CLOUD Act. This is where most "GDPR compliant software" claims live.
3. Rung 2: US company, separate EU sovereign offering. A dedicated European entity, EU-resident staff, infrastructure separated from the global platform. AWS opened its European Sovereign Cloud in Germany in January 2026, run through German legal entities and operated by EU residents, backed by a EUR 7.8 billion investment (AWS, 2026). The parent company is still American.
4. Rung 3: European company, US infrastructure. The vendor is European, but it runs on a US hyperscaler or relies on US sub-processors for email delivery, analytics or AI. Better contractual footing, same plumbing underneath.
5. Rung 4: European company, European infrastructure and sub-processors. European legal entity, European hosting, European sub-processors throughout. This is what most people imagine when they say "sovereign cloud."
6. Rung 5: You hold the keys. Self-hosted or open-source software on infrastructure you control, or a provider where only you hold the encryption keys. Maximum control, maximum responsibility.

Two important notes. First, higher is not automatically better. Rung 5 means you own the patching, the backups and the 2 a.m. outage. Second, different tools deserve different rungs. Your marketing analytics might live happily on rung 1 while your HR system belongs on rung 3 or 4.

Worked example: how many US vendors touch your data?

Let's make this concrete. Picture a 60 person digital agency in Amsterdam. Nothing unusual about it. Here is a fairly typical stack:

1. Email, calendar and docs: Google Workspace
2. Team chat: Slack
3. Video calls: Zoom
4. CRM: HubSpot
5. Wiki: Notion
6. File sharing with clients: Dropbox
7. E-signatures: DocuSign
8. Automations between tools: Zapier
9. Design: Figma
10. Project management: a European tool
11. Payroll: a local Dutch provider
12. Accounting: a local Dutch provider

Now count.

• US-headquartered vendors: tools 1 to 9. That is 9 of 12, or 75%.
• Tools holding personal data about employees or customers: email, chat, video recordings, CRM, wiki, files, e-signatures, payroll and accounting. Call it 9 tools, and 7 of those 9 are American.
• Hidden layer: suppose the European project tool and the payroll provider both host on a US hyperscaler (very common, and you will only know by checking their sub-processor lists). Now 11 of 12 tools, about 92%, have a US company somewhere in the data path.

Now the part nobody budgets for. Say each vendor lists around 10 sub-processors (some list fewer, plenty list more, so check yours). Twelve vendors times 10 is 120 sub-processor entries to review. After removing duplicates (the same three cloud giants appear again and again), you might be down to 40 or 50 unique companies. That is your real data map.

Notice what is not the conclusion here. The conclusion is not "this agency is breaking the law." With the Data Privacy Framework currently in force and proper contracts in place, it may be fully compliant. The conclusion is that the agency's sovereignty depends almost entirely on one transatlantic arrangement that is under appeal, and nobody in the company has written that risk down.

The 20 to 200 person sovereignty audit

You do not need a consultant for the first pass. You need a spreadsheet, the company card statements and a free afternoon. Here is the step-by-step version.

1. List every tool. Pull 12 months of card and invoice data. Every recurring SaaS charge is a tool, including the ones a single team signed up for on a Friday.
2. Mark what data each tool holds. Use three buckets: sensitive (HR, health, salary, customer personal data), business (contracts, financials, product plans) and low risk (public marketing assets).
3. Find where the data is stored. Check the vendor's trust or security page. Can you choose a region? Are backups and support logs in the same region?
4. Identify the legal entity you contract with, and its parent. Your contract might be with an Irish subsidiary, but if the parent is in California, the CLOUD Act question still applies.
5. Get the DPA. Under GDPR Article 28(3), a processor contract must cover things like processing only on your documented instructions, security measures, and deleting or returning data when the service ends (GDPR Art. 28). If a vendor cannot send you a DPA, that is your answer.
6. Get the sub-processor list and the change process. Article 28(2) says a processor cannot bring in another processor without your prior authorisation, and if you gave general authorisation, it must tell you about changes so you can object (GDPR Art. 28). Ask how they notify you. Subscribe to it.
7. Check the transfer mechanism. If data goes to the US, is the vendor certified under the Data Privacy Framework, or relying on standard contractual clauses? Write down which. If the framework falls, you will want to know which tools are affected within an hour, not a month.
8. Test the exit. Can you export everything in a usable format? The EU Data Act helps here: for services in scope, switching contracts must cap the notice period at two months and the transition at 30 calendar days (Data Act Art. 25), and from 12 January 2027 providers may not charge switching fees at all (Data Act Art. 29). Actually run one export. It is the fire drill you will be glad you did.
9. Ask who holds the encryption keys and who can access your data for support. "Encrypted at rest" with the vendor holding the keys is normal, but it is not the same as you holding them.
10. Score each tool on the ladder. Put a rung number next to each one. Highlight any sensitive-data tool sitting on rung 0 or 1.
11. Decide, document, repeat. For each highlighted tool: accept the risk, add safeguards, or plan a move. Review once a year, or whenever transatlantic data news hits the headlines.

Why bother documenting? Because GDPR fines for unlawful international transfers can reach EUR 20 million or 4% of worldwide annual turnover, whichever is higher (GDPR Art. 83). Small companies rarely see numbers like that, but "we had a list and a reason for every tool" is a much better conversation with a regulator than "we never looked."

The honest trade-offs

Here is where most sovereignty articles turn into a sales pitch. Let's not.

US software is often excellent

Many US tools are mature, well funded and genuinely good at what they do. Integrations, AI features and the sheer number of people who already know how to use them are real advantages. Choosing a European tool that your team hates is not a win for sovereignty. It is a win for shadow IT.

The big US vendors are responding

Microsoft announced in April 2025 that it would increase its European data centre capacity by 40% over two years and commit, in contracts with European governments, to contest in court any government order to suspend its European cloud services (Microsoft, 2025). AWS built a separate European sovereign cloud. These moves do not remove the CLOUD Act question, but they do move these providers up the ladder.

Switching has a real cost

Do the math before you announce a migration. Take 50 people, 4 hours each of retraining and lost productivity, at a loaded cost of EUR 40 an hour. That is 50 times 4 times 40, or EUR 8,000, before you count the migration work itself, broken integrations and the colleague who insists the old tool was better. That is not a reason to stay put. It is a reason to move with a plan and to move the high-risk tools first.

Sovereignty is risk management, not a moral badge

The useful question is not "is this tool European?" It is "if the legal ground under this tool shifted tomorrow, how bad would that be, and how fast could we move?" For a public marketing site, the answer is "not bad." For your HR records, client contracts and internal chat, the answer might be different.

Mistakes to avoid

We have seen companies get excited about sovereignty and then trip over the same handful of things.

• Falling for sovereignty washing. "EU data residency" and "sovereign" are not synonyms. A US company storing data in Frankfurt is rung 1, not rung 4. Ask about the legal entity, the parent company and who operates the service, not just the data centre address.
• Ignoring sub-processors. A European vendor that sends your data through a US email delivery service, analytics tool or AI model is still sending it to the US. The sub-processor list is where the truth lives.
• Forgetting the integration layer. Automation tools that pipe data between your apps are processors too. A perfectly sovereign CRM connected through a US automation service has a US hop in the middle.
• Overlooking AI features. New "summarise this thread" buttons often call a third-party model provider. Check whether that provider appears on the sub-processor list, and where it processes data.
• Treating "GDPR compliant software" as the end of the conversation. GDPR compliance is about lawful processing. Digital sovereignty is about control and resilience. A tool can be fully compliant today and still leave you exposed if the transfer framework it depends on falls.
• Going all or nothing. Ripping out every tool at once is how migrations fail. Move the sensitive-data tools first, prove it works, then decide on the rest.
• Never testing the exit. A vendor that promises easy export but has never been tested is a promise, not a plan.
• Assuming "European" means "safe." A European vendor can still have weak security, a vague DPA or a sub-processor list full of US names. Apply the same checklist to everyone.

Where Tixio fits, and what you should ask us

We build Tixio, so read this section with that in mind.

Tixio is a Work OS built by Tixio Technologies AS, a Norwegian company based in Ulefoss. It brings chat, projects, HR, CRM, wiki, boards and canvas into one app. Norway is not in the EU, but it is in the EEA, and GDPR has applied there since 20 July 2018 (Datatilsynet).

Why does an all-in-one tool matter for sovereignty? Go back to the worked example. Every separate tool is another DPA to read, another sub-processor list to track and another export to test. When chat, project management, leave requests, rosters and your CRM pipeline live in one workspace, the audit gets shorter. Fewer vendors means fewer contracts, fewer sub-processor lists and fewer places for data to leak between integrations. We wrote about how agencies cut their app stack in half if you want to see what that looks like in practice.

Now the important part. A Norwegian headquarters on its own puts a vendor on rung 3 at minimum. It does not prove rung 4. So do with us exactly what you do with everyone else:

• Ask us for our DPA.
• Ask us for our full sub-processor list and how we notify you of changes.
• Ask us where your data is hosted and where backups live.
• Ask how export works, and try it during the trial.

If a vendor, including us, gets vague on any of those, treat that as a signal. If you are specifically looking for a European alternative to Slack, our Slack alternatives roundup and Tixio vs Slack comparison cover features as well as fit. And for the wider category, see our list of the best work management software.

Go deeper on sovereignty and data

• Data residency vs data sovereignty vs data localization, explained
• Shadow IT and shadow AI: where your data quietly leaks

Start with one question this week

You do not need to solve digital sovereignty this quarter. You need to know where you stand.

So pick one tool, ideally the one holding your most sensitive data, and ask its vendor four things: who is the legal entity, where is the data, who are the sub-processors, and how do we leave. Write down the answers and put a rung number next to it. Then do the next tool next week.

Twelve tools, twelve weeks, and you will understand your stack better than most companies ten times your size.

If you want to see what consolidating chat, projects, HR and CRM into one European-built workspace looks like, you can try Tixio free for 14 days, no credit card required. And yes, ask us for the DPA first.
