TopSolid: sovereignty score and 8 European alternatives

TopSolid is a French publisher of integrated software for CAD, CAM, PDM and ERP. According to its website, the company offers solutions for several industries, covering design, machining programming, product data management and company processes. Until 2019 the business traded as Missler Software; in that year it was renamed TopSolid.

The publisher is TopSolid SAS, a French company, and its registered office and headquarters are in Evry, France. When the management team took over the group in 2019, an investor group led by Siparex, including Bpifrance and IRDI, took a stake, as the company announced in a press release. The company names no foreign parent company. For a European organisation this means a French headquarters and French shareholders as reported at the 2019 takeover.

Why digital sovereignty matters with TopSolid

TopSolid is headquartered in FR 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 TopSolid scores best on data residency.

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