onOffice: sovereignty score and 8 European alternatives

onOffice is real estate software for independent property firms. According to the vendor's homepage, the offer includes a CRM, a mobile app, websites, an AI studio and an online marketplace. Users sign in through a cloud login.

onOffice GmbH is based in Aachen, Germany, so the vendor falls under EU and German law. The vendor's privacy page states that its own processors are bound by data processing agreements or EU standard contractual clauses. The sub-domains of its websites are hosted by a German provider inside the EU. The page does not say where the customer data of the software itself is stored. The product is not offered as open source or as a self-hosted solution. Organisations should record the hosting location in the data processing agreement.

Why digital sovereignty matters with onOffice

onOffice is headquartered in DE 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 onOffice scores best on data residency.

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