Digital sovereignty is less about where something was manufactured than about who gets to decide how it is used. Supply chain dependency — the silicon, the accelerators, the firmware — is for most organisations unavoidable. Dependence — a control plane, keys, or an audit trail held by someone else — is a choice, and usually a reversible one.

The European Commission’s Cloud Sovereignty Framework scores this across eight objectives (strategic, legal, data & AI, operational, supply chain, technology, security, sustainability) on SEAL levels 0–4; Scrydon’s Cloud Sovereignty Score implements it as a self-assessment. Notably, supply chain carries the smallest weight of the major objectives — operational and technology sovereignty carry more.

The same argument scales all the way down to a home battery: see #Home Assistant and #Home Energy Management, and up to a #AI OS running air-gapped or on-premise.
