Storagecenter: sovereignty score and 8 European alternatives

Storagecenter is an S3-compatible object storage service for businesses, developers and backup users. It runs on a multi-availability-zone Ceph cluster, offers a web interface (bucket browser) with sharing and multi-factor authentication, and provides Object Lock (WORM) for immutable backups. According to the vendor, common S3 tools and backup applications such as Veeam, Rclone, Kopia and Cyberduck work without changes, as do NAS systems from Synology, QNAP and others. The website states that there are no extra charges for API requests or traffic.

Storagecenter is operated by zettatec GmbH in Wintersingen, Switzerland, a company the website describes as owner-managed. According to the vendor, data is stored exclusively in Swiss data centres, and it says it works with no third-party providers. It describes the service as compliant with the Swiss data protection act (revDSG) and the GDPR. Switzerland is not in the EU but is an EFTA country with an EU adequacy decision. For European organisations this means storage outside the EU but, as far as the website shows, with no foreign parent company.

Why digital sovereignty matters with Storagecenter

Storagecenter is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

Storagecenter hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

Storagecenter is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Storagecenter together with your other vendors and gives a total score, a heatmap and the main risk drivers.
