ATTIC+: sovereignty score and 8 European alternatives

ATTIC+ is a family of software for construction economists, estimators, contractors, architects and engineering offices. It covers quantity take-off with graphical 3D input from PDF, DWG/DXF or IFC files (Easy-KUTCH), written specifications and quantities (WinDESC-WinQUANT), tender management (WinOFFRE), financial management of building sites (WinCHANT) and 3D earthworks measurement (CubaTTIC). BIM workflows are supported through an IFC import and export module and a plug-in for Revit. The products are licensed, either purchased or rented, with a maintenance contract, and an integrated cloud space is available for sharing projects and documents.

ATTIC + is a French SAS with its registered office in Boulogne-Billancourt, and its site names no foreign parent. For the core software, the pages consulted describe no vendor-hosted service, and they do not state where the cloud space is hosted; organisations that use it should ask. The privacy policy refers to the GDPR. For a European organisation this is French software sold under a licence model.

Why digital sovereignty matters with ATTIC+

ATTIC+ 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.

ATTIC+ runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

ATTIC+ is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs ATTIC+ together with your other vendors and gives a total score, a heatmap and the main risk drivers.
