Storware: sovereignty score and 8 European alternatives

Storware is backup software from Storware sp. z o.o. in Warsaw. The platform provides agentless, policy-driven backup and recovery for virtual machines, containers and cloud environments, managed from a single console. It is aimed at organisations running mixed virtualisation estates. The product is sold as software and as a turnkey backup appliance, and the backup infrastructure runs on systems the customer operates itself.

The company is headquartered in Warsaw, and the website names no owners or investors. Storware Cloud, an off-site storage service, is mentioned, but the site does not say where its data is located. The privacy notice, which is based on the GDPR, states that some transfers go outside the EEA under adequacy decisions and standard contractual clauses. For a European organisation, the Polish base and the customer-run deployment are the main sovereignty-relevant features; where off-site copies held in the cloud are stored should be confirmed with the vendor.

Why digital sovereignty matters with Storware

Storware 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.

Storware 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.

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