ProSimPlus: sovereignty score and 8 European alternatives

ProSimPlus is a process-engineering tool from Fives ProSim for steady-state process simulation. It performs rigorous mass and energy balances for a wide range of continuous industrial processes and is used in design, process optimisation, debottlenecking, revamping and feasibility studies. The vendor describes a library of unit operations, including three-phase and reactive distillation and brazed plate heat exchangers, a thermodynamic library for strongly non-ideal systems, and an open design with user-defined unit operations, Visual Basic scripts and CAPE-OPEN support. The same company also offers a Python API and products for energy, thermodynamic and dynamic simulation.

Fives ProSim S.A.S. has its registered office in Labège, France, and belongs to the Fives group, whose registered address is in Paris; no foreign parent is named. The pages consulted describe no vendor-hosted cloud service, but a program with a graphical interface that is delivered together with services and training. Check with the vendor how and where it is run. The privacy information on the site is limited to website data.

Why digital sovereignty matters with ProSimPlus

ProSimPlus 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.

ProSimPlus 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.

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