Security Auditing

Lynis is our system and security auditing tool for Linux, Mac OS X, and UNIX-based systems.

It provides insights in how well a system is hardened and what you can do, to improve your security defenses.

The software is open source and free to use. It is updated on a regular basis, to keep up with new technologies.

Security should be simple, but it is definitely not. With Lynis you gain quick insights in how well you are protecting your crown jewels. From your personal notebook to surf the web, up to where your company’s biggest secrets are stored.

Target audience: system administrators, security engineers, auditors and consultants.

Try now: Download Lynis or clone it via GitHub.


Commercial support available

For companies who prefer additional support, we have also Lynis Enterprise. It uses Lynis as a client. On top of that, it has additional plugins, reporting, central management, a dashboard, and more guidance (e.g. hardening snippets). With Lynis in its core, you are assured of a stable piece of software, which is up-to-date.

Examples of plugins:

  • Compliance (e.g. HIPAA, PCI DSS, ISO27001)
  • Docker
  • File integrity
  • Systemd


Lynis and Blogging?

We learn a lot while developing the tool and our research. So this is the reason for us to blog about it. At the same time, it gives more people access to information and to the tool. Got feedback to improve something? Use the contact form and let us know.
