High sovereignty because German/EU-based cloud provider; strong EU operations, but US investor stake and global supply chain reduce sovereignty.

| Criterion | Score | Short Assessment | Long Rationale |
|---|---|---|---|
| SOV-1 (strategic) | 3 | EU HQ; US investor stake. | IONOS Group SE is EU-based and majority-controlled by United Internet (Germany), but Warburg Pincus (US) retains a material stake. Strategic control is EU-led but not exclusively EU-owned. → SEAL-3. |
| SOV-2 (legal) | 3 | EU law; non-EU exposure. | Operations are governed under German/EU law, but the shareholder structure includes a US investor, creating residual non-EU exposure. → SEAL-3. |
| SOV-3 (data & AI) | 3 | EU data centres available; encryption control customer-managed, not zero-knowledge. | IONOS offers EU-based data centre regions and does not rely on US hyperscaler runtime control. However, encryption is customer-configured rather than enforced zero-knowledge and hardware supply chains remain globally sourced. Data sovereignty is strong but not fully insulated from structural non-EU technology dependencies. → SEAL-3 |
| SOV-4 (operational) | 4 | EU-operated infrastructure without hyperscaler runtime dependency. → SEAL-4 | IONOS operates and supports its own cloud infrastructure from EU-based data centres under EU jurisdiction, without relying on AWS, Azure, or Google Cloud for runtime control. Operational management, support, and service continuity are delivered within the EU, enabling independent EU operation without foreign vendor involvement. → SEAL-4 |
| SOV-5 (supply chain) | 2 | EU-operated cloud; hardware and firmware globally sourced. | IONOS operates EU-controlled data centres without hyperscaler dependency, but server hardware, processors, and firmware ecosystems are globally sourced and not EU-controlled. These structural non-EU supply chain dependencies constitute material exposure under SOV-5. → SEAL-2 |
| SOV-6 (technological) | 3 | EU cloud stack; interoperable services, but not fully open. | IONOS supports standard interfaces and EU-operated infrastructure, improving portability and reducing hyperscaler lock-in. However, core platform components are not fully open-source/auditable end-to-end and depend on globally governed hardware/software layers. → SEAL-3 |
| SOV-7 (security) | 4 | EU-operated certified cloud; sovereign security governance. | IONOS operates EU-based infrastructure with certified security controls and EU-governed compliance operations. Security architecture and incident response are controlled within EU jurisdiction without hyperscaler runtime dependency, supporting full sovereign security governance under SOV-7. → SEAL-4 |
| SOV-8 (environmental) | 4 | Publishes PUE and renewables reporting; strong evidence. | IONOS publishes sustainability reports with data-center sustainability measures, including explicit tracking of data-center efficiency metrics (PUE) and renewable electricity claims, aligning closely with SOV-8 contributing factors. Transparent reporting and quantified targets support high-assurance sustainability scoring. → SEAL-4 |
