01Assess sovereignty objectively, not by the label
Before selecting, every solution is checked against a fixed set of criteria: where is data processed, who is the operator and legal entity, is there a DPA, is training on input excluded, are several models available, and is there independent evidence such as ISO 27001 certification? That turns the vague claim "from Europe" into a verifiable decision — documentable to management, data protection and the works council.
02Process sensitive data on suitable models
For particularly critical applications a European or open-source model is chosen, while for general tasks the most capable suitable model — hosted GDPR-compliantly in the EU — is used. The right model per task instead of lock-in to a single vendor: sovereignty is maximised where data sensitivity demands it, without giving up performance on everyday work.
03Roll out GDPR-compliant access across the company
Every employee gets central, EU-hosted access with permission management and SSO — instead of private accounts with US services whose data flows nobody controls. Company knowledge no longer ends up scattered across third-party accounts, but in an environment whose data protection the company can guarantee contractually and evidence.
04Reduce vendor dependency
Because several models are available behind one interface, the model can be swapped if a vendor changes prices, availability or policies — without rebuilding processes. Digital sovereignty also means strategic resilience: not depending on the terms or availability of a single foreign vendor.
05Avoid third-country transfers and replace shadow AI
Instead of employees copying sensitive content into private US AI accounts (shadow AI), input flows through an EU-operated platform with clear processing paths. Uncontrolled third-country transfers are replaced by a vetted, logged environment — the basis for being able to present AI use as compliant at all.
06Make data protection and sovereignty evidenceable
Audit logs, central permission management and documented processing make it evidenceable to data protection officers, the works council and auditors which data flows where and who has access. Independent evidence such as ISO 27001 certification and penetration-test reports turns the sovereignty claim into a verifiable operating state.
