Blomp: sovereignty score and 8 European alternatives

Blomp is a cloud service for storing and backing up photos, videos, audio and documents. It is aimed at individuals and works through a web browser and through apps for Windows, Mac, Ubuntu Linux, iPhone and Android. Blomp offers a free storage allowance that can grow by inviting friends, as well as paid plans with more space. According to Blomp, it does not share, sell or analyse your data.

According to its privacy policy, Blomp is based in the United States, and its terms of use are governed by California law. By using the website, you agree to the transfer of personal data to the US. For transfers from the EEA, the EU and Switzerland, Blomp relies on the EU-US Data Privacy Framework, under which it has self-certified. The website, privacy policy and terms do not state where its data centres are located. The service is not open source. A European organisation that needs control over storage location should ask Blomp for written confirmation before using the service.

Why digital sovereignty matters with Blomp

Blomp 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.

Data is hosted exclusively in the EU, so Blomp scores best on data residency.

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