Octopus: sovereignty score and 8 European alternatives

Octopus is Belgian accounting software for entrepreneurs and accountancy firms. The platform works as a collaboration environment between businesses and their accountants, with files managed in the cloud. Octopus also acts as a Peppol access point provider, which allows users to send and receive electronic invoices over the Peppol network. The product is offered as cloud software.

The operating company is Octopus NV, based in Gentbrugge, Belgium. Its privacy statement refers to the GDPR (Regulation 2016/679), but does not state where data is hosted or list sub-processors; only the newsletter provider MailerLite is named. The company's ownership is not stated. Octopus is not open source, and no self-hosted option is described, so a European organisation can ask the vendor for hosting details and a data processing agreement.

Why digital sovereignty matters with Octopus

Octopus is headquartered in BE 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 Octopus scores best on data residency.

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