Mastercam: sovereignty score and 8 European alternatives

Mastercam is a CAM software package for programming CNC machines, including milling and turning equipment. Users create machining programmes from CAD drawings. The software is developed by CNC Software, LLC, based in Tolland, Connecticut, in the United States. Besides the software, the vendor offers online services such as a customer portal and the Mastercam CONNECT environment. It is used by machining companies, toolmakers and manufacturers that run CNC equipment.

In 2021 the Swedish industrial group Sandvik announced its acquisition of CNC Software; Sandvik's head office is in Stockholm. The parent therefore sits in Sweden, inside the EU, while the developer CNC Software is a US company. Mastercam's privacy statement refers to the GDPR. The sources consulted do not state where customer data is stored, so the vendor should be asked for its data processing agreement and its list of sub-processors.

Why digital sovereignty matters with Mastercam

Mastercam is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model. The ultimate owner is based in SE, also within Europe.

Mastercam hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

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