Nexus AG: sovereignty score and 8 European alternatives

NEXUS AG is a German healthcare software company based in Donaueschingen. Its core product is NEXUS / KISNG, a clinical information system for hospitals. The company also supplies modules for laboratories (NEXUS / LAB), radiology and VNA, a patient portal and an AI tool for discharge letters, together with IT services and a service desk. Its customers are hospitals and clinics, psychiatric facilities, rehabilitation and care homes, laboratories and hospital IT departments. The website also lists a NEXUS / CLOUD IT offering but does not describe a delivery model or hosting location.

In 2025, Project Neptune Bidco GmbH, a holding company controlled by funds advised by TA Associates, took the company over through a public takeover offer. TA Associates is a US private equity firm headquartered in Boston. The company therefore has a US owner, which is relevant to CLOUD Act exposure. NEXUS is not open source. It is advisable to fix the data processing location contractually.

Why digital sovereignty matters with Nexus AG

Nexus AG 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. The ultimate owner is based in US. Foreign control undermines part of the certainty a European headquarters offers.

Data is hosted exclusively in the EU, so Nexus AG scores best on data residency.

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