ImmOpen: sovereignty score and 8 European alternatives

ImmOpen is a software suite for property administrators, such as condominium managers, rental managers and estate agents. Three business lines share one interface: ImmOpen Syndic (building accounting, events and service orders, budgets, general meetings), ImmOpen Gestion locative (listing properties, tenant selection, inventories, billing) and ImmOpen Transaction (sales mandates, offer publication, viewings). Optional modules cover document dematerialisation, electronic signature, meeting tools, a tenant-application space and the ImmoViz mobile app. According to the vendor, improvements are released every quarter.

ImmOpen is published by IdealSoft, a French company (Ideal Soft Informatique Sud SAS) based in Saint-Clément-de-Rivière. No foreign parent company is named on its website. The vendor does not state whether ImmOpen is delivered as installed software or as a hosted service, nor where data is stored; the website itself is hosted by the French provider OVH. For a European organisation this means French jurisdiction for the vendor, while the delivery model and data residency should be confirmed with IdealSoft before purchase.

Why digital sovereignty matters with ImmOpen

ImmOpen is headquartered in France 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 ImmOpen scores best on data residency.

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