SEMA Software: sovereignty score and 8 European alternatives

SEMA Software is a family of 3D CAD and CAM programs for timber construction, stair design and sheet metal work. The software combines 3D design with planning and calculation tools for carpentry, prefabrication, roofing and sheet metal workshops. The vendor's website links to a program download and to hardware recommendations for the workstation, and it lists separate solutions for timber construction, carpentry, prefab, and roofing and sheet metal.

SEMA GmbH, whose full legal name is SEMA GmbH Computer Software und Hardware-Vertrieb, is registered in Germany with its seat in Wildpoldsried in Bavaria. Its legal notice names three managing directors and does not mention an owner or parent company. The website does not state where customer data is processed or hosted. For a European organisation, the vendor is a German company, and whether design data stays on the company's own systems depends on the installation and on the update service, which the vendor should explain in writing.

Why digital sovereignty matters with SEMA Software

SEMA Software 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 SEMA Software scores best on data residency.

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