CLOUD Act 2026 – Why US Cloud Services Are No Longer Legally Tenable in the EU

The CLOUD Act (Clarifying Lawful Overseas Use of Data Act) obligates US providers like Microsoft, Google, Amazon, Apple, and Meta to hand over their customers' data to US authorities globally — regardless of where the servers are physically located. Even if your data sits in Frankfurt, Dublin, or Amsterdam.

In 2026, the situation has escalated sharply.

What changed in 2026?

1. New US Executive Orders

In its first 100 days, the second Trump administration signed several executive orders that effectively eliminate judicial oversight of CLOUD Act requests. The EU-US Data Privacy Framework (DPF) — which was already only a Commission adequacy decision — is politically obsolete, even if it formally remains.

2. Microsoft admitted it

In 2025, Anne Hoge, Chief Legal Counsel of Microsoft France, testified under oath before the French Senate: Microsoft cannot guarantee that data within its "EU Data Boundary" will never be disclosed to US authorities. That's the honest answer to the CLOUD Act — and it makes every Microsoft deployment in critical infrastructure legally vulnerable.

3. Schrems III is coming

Max Schrems announced his third lawsuit in 2025. Schrems II killed Privacy Shield in 2020. Schrems III targets the DPF — and most observers expect a third ruling in favour of the plaintiffs. Not a question of if, but when. At the same time, the NIS2 Directive has bound around 29,000 German companies to strict information-security duties since 2026 — and Microsoft 365 is structurally incompatible with BSI IT-Grundschutz requirements.

What does this mean for you concretely?

If your company uses any of these tools today, you're affected:

Each of these platforms is subject to the CLOUD Act. As soon as personal data is processed — which, given email addresses, phone numbers, and customer names, is almost always the case — GDPR compliance becomes questionable.

Regulators are tightening

• German Datenschutzkonferenz (DSK): Recommendation against Microsoft 365 in public schools
• Berlin DPA: Warning against Microsoft 365 in public administration
• Hesse DPA: Prohibition of Microsoft 365 in schools
• NRW, Lower Saxony, Baden-Württemberg: Active exit in agencies and schools
• EU Commission: Migrating internal communications to Matrix/Element

When public bodies migrate, it's a clear signal: their legal teams see the risks concretely and now.

What's the alternative?

Sovereign, EU-hosted open-source infrastructure. Specifically:

• Microsoft 365 → Nextcloud + ONLYOFFICE + Element
• Outlook → mailcow / Stalwart Mail
• Teams → Matrix/Element + Element Call
• OneDrive / SharePoint → Nextcloud
• OneNote → Nextcloud Notes
• Active Directory → Keycloak
• LastPass / 1Password → Vaultwarden

All run on European servers (Hetzner, OVHcloud, Scaleway, IONOS), are fully GDPR-compliant, and are not subject to the CLOUD Act.

Conclusion

The CLOUD Act isn't new — but in 2026 it has become unavoidable. Anyone still relying on US cloud services without a migration plan is taking an avoidable compliance risk. Europe's political climate could hardly be more favourable for the move.

Sovereignty isn't ideology. It's risk management.
