Znuny: sovereignty score and 8 European alternatives

Znuny is an open-source service desk and ticketing system that began as a fork of the OTRS Community Edition 6.0.x and continued that line after OTRS AG ended support for it. It offers ticket management through email and a customer portal, templates and text snippets, an FAQ and knowledge base, integration with third-party systems such as CRM and databases, and SLA management. It is free of charge and released with long-term support (LTS). Znuny runs on your own servers or with any cloud provider you choose. Znuny GmbH also offers support, training, consulting, development and hosting.

Znuny GmbH is based in Berlin, Germany. The software is open source and distributed for you to install yourself, so you decide where data resides and who administers it. That suits European organisations that want to operate independently of a US cloud provider. The pages consulted name no parent company and no fixed hosting location for the hosting service on offer.

Why digital sovereignty matters with Znuny

Znuny 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.

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

Znuny is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Znuny together with your other vendors and gives a total score, a heatmap and the main risk drivers.
