Sovereignty Scorecard
Procurement-grade signals on data sovereignty, ownership, and EU residency.
We score every European vendor against six sovereignty dimensions captured in the SHIELD acronym. Each card below maps to one letter — read them as a checklist when comparing providers.
The third parties that touch customer data — payment processors, KYC vendors, support chatbots, analytics.
Where the legal entity sits, who controls it, and which subsidiaries operate under the same group.
Where customer data is physically stored, who runs the hosting stack, which CDN sits in front.
Whether the vendor or its subprocessors fall under the US CLOUD Act or other extraterritorial reach.
Public terms, privacy policy, DPA, subprocessor list, impressum, and security or trust pages.
Independent audits and certifications (ISO 27001, BSI C5, TISAX, SOC 2) plus open-source transparency.
