What the US CLOUD Act Means for EU Customers
Yes — the US CLOUD Act (2018) authorises US law enforcement to compel US-based service providers to produce data they control regardless of where it is stored. A US-parent vendor that hosts EU customer data in Frankfurt is still subject to a US warrant. EU data residency is necessary but not sufficient for CLOUD Act protection.
Does the US CLOUD Act apply to EU customers of US vendors?
Yes — the US CLOUD Act (2018) authorises US law enforcement to compel US-based service providers to produce data they control regardless of where it is stored. A US-parent vendor that hosts EU customer data in Frankfurt is still subject to a US warrant. EU data residency is necessary but not sufficient for CLOUD Act protection.
- The CLOUD Act applies to US-headquartered companies and their subsidiaries — not to where the data is physically stored
- EU customers should evaluate vendor corporate structure (headquarters + parent), not just data-residency contractual terms
- EU-EU vendor pairings (EU customer + EU-headquartered vendor + EU hosting) are the strongest configuration against CLOUD Act compulsion
- Schrems II (CJEU C-311/18) addressed transfers to the US, not direct US-compelled access — the two are distinct legal regimes
