Open-E: sovereignty score and 8 European alternatives

Open-E develops JovianDSS, a software-defined storage platform based on ZFS and Linux. It is aimed at organisations that want to build their own SAN and NAS storage on standard server hardware. Depending on the configuration, it offers high-availability clusters, data protection, deduplication and encryption. A second product, JovianVHR, provides an immutable backup repository qualified for Veeam. Plugins for Proxmox VE cover iSCSI and NFS. The software is licensed and installed on the customer's own servers or certified partner systems.

Open-E, founded in 1998, operates through Open-E Sp. z o.o. in Bytom (Poland), Open-E GmbH in Puchheim near Munich (Germany), Open-E, Inc. in Marietta, Georgia (USA) and an office in Japan. Its website names no single headquarters or owner. The product is proprietary, not open source. Because the software runs on infrastructure you choose, you decide where the data is stored, for example in a European data centre. Check which Open-E entity is the contracting party.

Why digital sovereignty matters with Open-E

Open-E is headquartered in PL and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Open-E scores best on data residency.

Open-E 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 Open-E together with your other vendors and gives a total score, a heatmap and the main risk drivers.
