Software houses, IT departments, programmers and start-ups use it to build Windows applications. User interface, program logic and data model sit under one roof: you design screens and printouts visually by drag and drop, write logic in a code editor with debugger and define the data structure in an editor. Data is accessible through ODBC, SOA, PHP or the OData REST API. Licences can be rented or bought, based on concurrent users. With yeet the vendor is also building a low-code platform.

Vectorsoft AG is a German stock corporation, and its website names no parent company. If you install conzept 16 yourself, data stays on your own systems. In the vectorsoft cloud, applications including conzept 16 Enterprise run with access via browser or RDP on a server in Germany, according to the vendor. For a European organisation the vendor falls under EU data-protection law; ask about the processing agreement and the data-centre operator.

Why digital sovereignty matters with conzept 16

conzept 16 is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

conzept 16 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.

conzept 16 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 conzept 16 together with your other vendors and gives a total score, a heatmap and the main risk drivers.
