Cubbit: sovereignty score and 8 European alternatives

Cubbit is an Italian company that provides S3-compatible object storage. DS3 Cloud is a ready-to-use service in which data is encrypted, fragmented and replicated across several locations, held in certified facilities operated by partners. DS3 Composer is software-defined storage that organisations deploy wherever they choose, aimed at large-scale installations. Use cases include backup, archiving, data lakes and Kubernetes storage, and the service works with backup tools such as Veeam, Acronis and Commvault. The target groups are enterprises and service providers, including white-label resellers.

Cubbit S.r.l. is headquartered in Bologna, Italy, and describes its technology as European. The product is not open source. According to the vendor, customers choose where their data is stored and localisation is guaranteed, and the service is positioned around GDPR alignment and ISO 27001. The vendor's website names no specific countries or data centre partners, so an organisation with data-residency requirements should confirm the exact storage locations in the contract.

Why digital sovereignty matters with Cubbit

Cubbit is headquartered in IT 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 Cubbit scores best on data residency.

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