Altair HyperWorks: sovereignty score and 8 European alternatives

Altair HyperWorks is a software suite for simulation, optimisation and design exploration in engineering teams. The portfolio spans simulation, high-performance computing, data science and AI tools. The HyperWorks 2026 release, announced in December 2025, extends accelerated simulation and AI-powered feedback. Altair is now part of Siemens' industrial software portfolio.

Altair Engineering was headquartered in Troy, Michigan, and was acquired by the German industrial group Siemens, a deal completed in March 2025. Because the parent is German, the product now sits within a European group. Siemens has stated that parts of the HyperWorks portfolio are being folded into its Simcenter simulation offering. European organisations should confirm with the vendor where cloud service data is stored and from which countries support staff can access it.

Why digital sovereignty matters with Altair HyperWorks

Altair HyperWorks 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 DE, also within Europe.

Altair HyperWorks 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.

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