Has anyone used OpenKAT?
Description
OpenKAT is an open-source project initiated by the Dutch government designed to monitor, record, and analyze the status of information systems. It integrates various network scanning tools and external databases to identify vulnerabilities and configuration errors, producing accessible reports to improve system security. The project is modular and extensible, allowing customization for different environments. There is no indication that OpenKAT itself is a security vulnerability or threat. Rather, it is a security tool aimed at vulnerability detection and system monitoring.
Reddit Discussion
This must sound very niche, especially since there are already established products such as Greenbone and Tenable Nessus. But I still want to ask.
I live and work in the Netherlands and I recently (like an hour ago) came across a project by the Dutch government called OpenKAT
It seems active in its development https://github.com/SSC-ICT-Innovatie/nl-kat-coordination
And I was wondering if there is anyone else out there who can tell me more on what is it compared to things such as greenbone and tenable nessus. Since I am very curious with the new NIS2 directive going into law very soon.

Technical Analysis
OpenKAT is a modular framework that scans networks, collects vulnerability data from integrated tools and external sources like Shodan, and generates reports to help identify and remediate known vulnerabilities and configuration errors. It is developed actively by the Dutch government and licensed under the EU Public License 1.2. The tool is designed to be secure by default in production setups and does not collect private information beyond what is publicly accessible. There is no evidence or indication that OpenKAT itself contains security flaws or is exploited.
Potential Impact
No direct security impact or vulnerability is described. OpenKAT is a security monitoring tool intended to improve security posture by identifying vulnerabilities and misconfigurations. There is no known exploitation or threat associated with OpenKAT itself.
Defensive Guidance
No mitigation actions are required as OpenKAT is not a vulnerability or threat. It is a security tool designed to detect vulnerabilities. Users should follow the official production setup and hardening guidelines provided by the OpenKAT documentation to ensure secure deployment.
