Lynis: sovereignty score and 8 European alternatives

Lynis is an open-source security auditing tool for Linux, macOS and other Unix-based systems. It runs locally as a command-line program and checks system configuration against hardening and compliance tests, reporting findings and suggestions. It is licensed under the GNU General Public License v3 and maintained by CISOfy. The latest release listed in the project changelog is version 3.1.7, dated 25 June 2026.

CISOfy is registered in the Netherlands and has its office in Vlijmen, so the company falls under Dutch and EU law. The source code is public on GitHub, so organisations can inspect it and run the tool on their own systems. Organisations that currently use commercial host-compliance scanners can use Lynis as an open-source alternative for configuration audits on their own servers.

Why digital sovereignty matters with Lynis

Lynis is headquartered in NL 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 Lynis scores best on data residency.

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