OnWork Cloud: sovereignty score and 8 European alternatives

OnWork Cloud is a managed business cloud from ONWORK CLOUD, S.L. in Tarragona, Spain. The private cloud runs a customer's systems on reserved, non-shared compute capacity with NVMe all-flash storage and an operations team that monitors and recovers the platform around the clock. The hybrid cloud combines on-premises systems with the cloud, and OnWork can also work alongside workloads that stay on Azure, AWS or Google Cloud. Related services include off-site backup against ransomware, disaster recovery sites and Microsoft 365 backup.

According to the vendor, the infrastructure is its own and not resold, and data, including the secondary recovery site and off-site copies, stays entirely in Spain with no international transfers in normal operation, under GDPR and European law. The vendor acts as processor under a data processing agreement, with contractual data portability and documented destruction at the end of the service. The company is Spanish and no foreign parent is stated. No self-hosted variant is offered. Have the sovereignty claims confirmed in the contract.

Why digital sovereignty matters with OnWork Cloud

OnWork Cloud is headquartered in ES 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 OnWork Cloud scores best on data residency.

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