Criterion Score Short Assessment Long Rationale
SOV-1 (strategic) 4 EU provider built on EU stack. Nextcloud One is offered by epiKshare GmbH with offices in Germany/AT/CH; entity listed in Germany. (Nextcloud One) Under SOV-1, decisive authority is EU-anchored and aligned with European sovereignty goals (Nextcloud ecosystem strongly EU-rooted). This supports SEAL-4 strategic sovereignty.
SOV-2 (legal) 4 EU law only. Germany is EU jurisdiction; the offering is clearly EU legal. That aligns with SEAL-4 for SOV-2.
SOV-3 (data & AI) 3 Strong control; hosting details unclear. Nextcloud-based solutions enable strong data control and can be run EU-only; however, for a hosted service offering, full SEAL-4 would require proof of no critical non-EU dependencies and customer-held cryptographic access by default. With limited public detail on hosting architecture and key control for this specific service, SEAL-3 is the defensible rating.
SOV-4 (operational) 4 Strong portability and operability. Open-source architecture enables migration, self-hosting and independent operation by EU actors. Operational autonomy is structurally achievable. → SEAL-4
SOV-5 (supply chain) 2 Global semiconductor reliance. Even with open software, underlying hardware/firmware and semiconductor supply chains remain global (material dependency). → SEAL-2.
SOV-6 (technological) 4 Open source, auditable stack. Nextcloud core is open source (AGPL) and designed for auditability and interoperability – squarely aligned with SOV-6 factors. This supports SEAL-4 for technology sovereignty (openness/transparency) even though hardware isn’t EU-made –> SEAL-4
SOV-7 (security) 3 EU compliance; specifics vary by operator. EU jurisdiction supports compliance; still, SOC and certification posture depends on the operator (epiKshare) and isn’t fully evidenced here. SEAL-3 is appropriate without additional certification proof.
SOV-8 (environmental) 2 Depends on hosting sustainability Open-source model enables efficient hosting choices, but hosted service lacks quantified environmental reporting. → SEAL-2
