¶ Political decisions: as of 6 September 2026
New political decisions checked on 6 September 2026; earlier background retains its stated reference date.
23.06.2026 — Business 26.3221 calls for a digital sovereignty stimulus programme. Its updated procedural status is assignment to the responsible committee. This does not establish an adopted or funded federal programme. Original source.
01.09.2026 — For business 24.3209 on sovereign digital infrastructure in the AI age, examination by the National Council committee is complete. This procedural step does not mean legislation is complete or infrastructure already operational. Original source.
04.09.2026 — The Administrative Delegation approved an approximately one-year PIA pilot from the autumn session, costing up to CHF 150,000 from the existing IT budget. Swisscom operates it in Switzerland using open-weight models, without training on inputs. Current internet research is not yet supported. Original source.
¶ In three sentences
Der sovereign Stack ist eine konkrete Software-Kombination, die Microsoft 365 ersetzen kann: Nextcloud (File, Calendar, Contacts), Collabora Online (Office), Paperless-ngx (DMS), Proton (E-Mail), Threema (Messaging), Infomaniak (Hosting). Alle Komponenten stehen ander Schweizer/EU-Jurisdiktion or werden on eigener Infrastruktur betrieben.
¶ Mechanics
Nextcloud (Hub 24/30) bietet Files, Mail, Calendar, Contacts, Talk, Office-Integration via Collabora; LDAP/SAML-Anbindung. Collabora Online ist LibreOffice-as-Server for gemeinsame Bearbeitung. Paperless-ngx verwaltet gescannte Dokumente mit OCR and Volltext-Suche. Proton Mail/Drive/Calendar sind Schweizer E2E-verschlüsselte SaaS-Dienste. Threema ist Schweizer Messenger mit eigenen Servern. Infomaniak (Schweiz) hostet Nextcloud-Instanzen.
Integration: Nextcloud als Zentrum, Proton or Mailcow als Mail-Backend, Collabora for Office, Paperless for DMS. Authentifizierung via LLDAP/Keycloak.
¶ What this means for Switzerland
Schweizer Beispiele for Komplett-migrationen sind dokumentiert: einzelne Gemeinden, KMU, Anwaltskanzleien, Arztpraxen. Die federal administration evaluiert Nextcloud (Pilotprojekte 2024); operativer Vollausbau steht aus. Hauptonwand: Identity-migration (von Entra ID zu Keycloak/LLDAP), Office-Workflow-transition, Schulung.
¶ Logical conclusion
Der sovereign Stack ist technisch reif and betrieblich erprobt. Die migration kostet Geld and Zeit, but sie ist machbar. Die Frage ist politisch — wer entscheidet, dass die sovereignty es wert ist.
¶ Implications for legislation
Note: The following points are recommendations from the FADS draft (Section 6) — not current law, but proposals for future Swiss legislation.
The FADS proposal (Art. 15-20) requires for sensitive data classes die Bevorzugung sovereignr Stack-Komponenten and einen 5-Jahres-migrationsplan for die federal administration.
