They reveal who a company works with, under what conditions, and where risks are concentrated across countries. Germany\u2019s Supply Chain Act (Lieferkettengesetz) and the EU Corporate Sustainability Due Diligence Directive additionally require detailed assessments along the entire chain.<\/p>\n<p>This information is highly sensitive. At the same time, it is generated and stored across multiple jurisdictions. A single cloud provider often manages data that falls under different national laws. Whoever controls this data gains detailed insight into a company\u2019s structure and dependencies. That is precisely why questions around legal access are more acute here than with most other workloads.<\/p>\n<h2 style=\"margin-top:64px;margin-bottom:20px;padding-top:16px;\">Residency is solved, sovereignty is not<\/h2>\n<p>Many companies have achieved physical data residency in Europe. The data resides in EU data centers. Sovereignty nevertheless remains unresolved. Under the US CLOUD Act, US authorities can compel any US-based provider to hand over any data over which it has possession, custody, or control. The storage location plays no role anywhere in the world. As long as the ultimate parent company is a US corporation, legal access remains.<\/p>\n<p>How theoretical this remains became clear in June 2025. The French Microsoft subsidiary confirmed under oath before the French Senate that it cannot guarantee data sovereignty toward US authorities. This applies even to data stored in France under an offering marketed as sovereign. The offerings of the US hyperscalers advertised as sovereign reduce risks related to residency, the location of operations staff, and parts of telemetry. They change nothing about the ownership structure. The CLOUD Act gap remains.<\/p>\n<div style=\"background:#004a59;border:1px solid rgba(11,183,253,0.4);border-radius:10px;padding:34px 26px;margin:36px 0;text-align:center;box-shadow:0 0 24px rgba(11,183,253,0.08);\">\n<div style=\"font-family:'SF Mono','Monaco','Consolas',monospace;font-size:11px;color:#0bb7fd;letter-spacing:0.14em;text-transform:uppercase;margin-bottom:10px;\">\/\/ Metric<\/div>\n<div style=\"font-size:48px;font-weight:700;color:#fff;letter-spacing:-0.03em;line-height:1;\">180 Mio.

It went to four European providers, not to the US hyperscalers.<\/div>\n<div style=\"font-size:12px;color:#0bb7fd;margin-top:12px;\">\/\/ Source: EU Commission, April 2026<\/div>\n<\/div>\n<h2 style=\"margin-top:64px;margin-bottom:20px;padding-top:16px;\">What&#8217;s Moving in 2026<\/h2>\n<p>On 1 June 2026, the European Commission published a formal assessment framework for cloud sovereignty. The framework evaluates providers across eight sovereignty objectives. A supply chain dimension is explicitly included. The CLOUD Act is specifically named in it as a legal risk. This caps US-owned providers from above, regardless of how many EU data centers they operate.<\/p>\n<p>This is more than just paper. In April 2026, the European Commission awarded a contract worth 180 million euros for a sovereign cloud solution for EU institutions. The contract went to four European providers rather than the US hyperscalers. The European sovereignty initiative Gaia-X reached more than 400 certified service providers in 2025. The Commission is thus not only defining sovereignty-it is also backing it with funding and an ecosystem.<\/p>\n<h2 style=\"margin-top:64px;margin-bottom:20px;padding-top:16px;\">What Teams Should Do Now<\/h2>\n<p>The first step is unspectacular and is nevertheless often skipped: classifying supply chain data by sensitivity. Not every supplier data record is equally critical. The truly competition-sensitive data and the due diligence data deserve the highest attention; the rest can be handled more pragmatically.<\/p>\n<p>Second, portability must be ensured. Contracts and architecture should allow a provider change without prohibitive costs and without data loss. Third, concrete sovereignty requirements belong in procurement: evidence regarding ownership structure, applicable legal jurisdiction, and existing access rights. The marketing label &#8220;sovereign&#8221; does not replace this review.<\/p>\n<p>Honestly: It remains open how strictly the EU framework will be applied in practice and how quickly European providers can scale for all critical supply chain workloads. Companies with global chains must also clarify how they consistently meet different national sovereignty requirements. A uniform standard for this is still lacking today.<\/p>\n<div style=\"display:grid;grid-template-columns:repeat(auto-fit,minmax(280px,1fr));gap:16px;margin:28px 0;\">\n<div style=\"background:#f7fbf9;border:1px solid rgba(45,122,62,0.22);border-radius:8px;padding:20px 22px;box-shadow:0 2px 8px rgba(0,0,0,0.03);\">\n<div style=\"font-family:'SF Mono','Monaco','Consolas',monospace;font-size:11px;color:#2d7a3e;letter-spacing:0.14em;text-transform:uppercase;margin-bottom:12px;\">\/\/ achieved<\/div>\n<ul style=\"margin:0;padding-left:18px;color:#1a2733;line-height:1.6;font-size:0.95em;\">\n<li style=\"margin-bottom:7px;\">The distinction between data residency and data sovereignty has arrived<\/li>\n<li style=\"margin-bottom:7px;\">The EU framework of June 1, 2026 provides a concrete framework with a supply chain dimension<\/li>\n<li>The 180-million-euro contract awarded to European providers sends a clear market signal<\/li>\n<\/ul>\n<\/div>\n<div style=\"background:#fbf8f6;border:1px solid rgba(181,83,42,0.22);border-radius:8px;padding:20px 22px;box-shadow:0 2px 8px rgba(0,0,0,0.03);\">\n<div style=\"font-family:'SF Mono','Monaco','Consolas',monospace;font-size:11px;color:#b5532a;letter-spacing:0.14em;text-transform:uppercase;margin-bottom:12px;\">\/\/ open<\/div>\n<ul style=\"margin:0;padding-left:18px;color:#1a2733;line-height:1.6;font-size:0.95em;\">\n<li style=\"margin-bottom:7px;\">CLOUD Act risks for US corporations persist, even with &#8220;sovereign&#8221; offerings<\/li>\n<li style=\"margin-bottom:7px;\">Practical enforcement of the framework in procurement and audits is still pending<\/li>\n<li>Global chains with data in many jurisdictions still require case-by-case review<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<h2 style=\"padding-top:64px;margin-bottom:20px;\">Frequently Asked Questions<\/h2>\n<details>\n<summary><strong>What is a sovereign cloud?<\/strong><\/summary>\n<p style=\"margin:8px 0 4px 24px;color:#555;line-height:1.6;\">A sovereign cloud ensures that legal sovereignty over data remains with the using organization or the applicable European jurisdiction.
