Cleondris ONE: sovereignty score and 8 European alternatives

Cleondris ONE is software for data protection and cyber resilience in NetApp ONTAP environments, developed by Cleondris AG of Steinhausen, Switzerland. It combines backup, ransomware detection and recovery in one platform for mid-sized and large organisations. Administrators can restore files at a granular level, work with immutable snapshots and AirGap copies via SnapMirror, and use SnapDiff-based ransomware monitoring. It also offers an FPolicy-based firewall, a four-eyes principle and SIEM connections. It works with NetApp ONTAP, on premises and in the cloud. Cleondris supplies a virtual appliance (OVA) for VMware ESXi that you install yourself.

Cleondris AG is based in Steinhausen (canton of Zug) and says it develops its products exclusively in Switzerland. The company describes itself as self-funded, and no foreign parent company is named. Switzerland is not an EU member state but is an EFTA country with a European adequacy decision for data protection. Because the software runs inside your own environment, you decide where backup data is stored; there is no vendor cloud for the production data. Note the dependency on NetApp technology.

Why digital sovereignty matters with Cleondris ONE

Cleondris ONE 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.

Cleondris ONE runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

Cleondris ONE is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

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