Proxmox: sovereignty score and 8 European alternatives

Proxmox Server Solutions develops a family of open-source products for virtualisation and data protection. Proxmox Virtual Environment (VE) manages virtual machines based on KVM and Linux containers (LXC), with clustering, high availability and support for storage such as Ceph and ZFS, operated through a web interface or the command line. Proxmox Backup Server creates incremental, deduplicated backups of virtual machines, containers and physical hosts, with optional client-side encryption. Proxmox Mail Gateway and Proxmox Datacenter Manager complete the range. The software runs on your own hardware; the company sells support and subscriptions.

The company is based in Vienna, Austria, and describes itself as independent, with its customers and supporters as its only investors. The code of products such as Proxmox VE and Proxmox Backup Server is licensed under the AGPLv3. Because you install the software yourself, you decide where the data is stored, for example in a European data centre, without depending on an external cloud service. No non-European parent company is known.

Why digital sovereignty matters with Proxmox

Proxmox is headquartered in AT 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 Proxmox scores best on data residency.

Proxmox is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

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