Naemon: sovereignty score and 8 European alternatives

Naemon is an open-source monitoring suite for networks and applications. It is based on the Nagios 4 core and adds bug fixes, new features and performance improvements. The software is installed and run on the organisation's own servers. ConSol offers paid support and consulting around Naemon, and the project site describes the project as community-owned.

Naemon is maintained by ConSol Software GmbH in Munich and is released under the GNU General Public License version 2. The project pages do not name a cloud service of their own, so monitoring data stays on infrastructure the organisation operates, and the operator chooses where it is hosted. For a European organisation, this means the software can run without depending on a foreign cloud provider, and its source code can be inspected and adapted under an open licence.

Why digital sovereignty matters with Naemon

Naemon 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 Naemon scores best on data residency.

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