Prosys OPC: sovereignty score and 8 European alternatives

Prosys OPC Ltd is a Finnish software company focused on OPC UA. Its portfolio includes developer tools such as SDKs for Java, .NET, C/C++ and Delphi, and applications such as the OPC UA Simulation Server, OPC UA Browser, OPC UA Gateway, OPC UA Monitor and Prosys OPC UA Forge, an industrial DataOps platform at the edge. The products are downloadable programs that developers and integrators install on their own systems, complemented by training, consulting and support. Founded in 1995 in Helsinki, the company has been based in Espoo since 1996.

Prosys OPC's website is hosted on servers within the European Union, as its privacy policy states. The company is an active member of the OPC Foundation. Its products run on the customer's own infrastructure, so the operational data they process can stay within the organisation's systems. Personal data is transferred outside the EU and EEA only where needed to deliver a requested service or licensed product, under applicable data protection rules. For a European organisation, this is a Finland-based OPC UA supplier with EU-hosted web services.

Why digital sovereignty matters with Prosys OPC

Prosys OPC is headquartered in FI and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Prosys OPC 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.

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