Storj: sovereignty score and 8 European alternatives

Storj is a decentralised cloud storage service offering S3-compatible object storage. Files are encrypted, split into pieces and spread across a global network of storage nodes. Storj also offers Object Mount, a client that makes object storage available like a local drive. The service is delivered as a hosted cloud service with an S3-compatible interface.

Storj Inc. is based in Atlanta, Georgia, in the United States, and its terms of service are governed by Delaware law. The core software is open source under the AGPL-3.0 licence. Stored data sits on devices run by third-party node operators, and the privacy policy does not name countries; Storj may transfer data to the United States on the basis of Standard Contractual Clauses. According to Storj, geofencing to European regions is available on request. For stored content Storj acts as processor and the customer is the controller. For a European organisation the main point is that the company is American, while the physical location of the pieces depends on the network and the chosen placement setting.

Why digital sovereignty matters with Storj

Storj is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Storj hosts data in US, EU, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

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