After a bachelor thesis from 2019 which recommended the Greenbone Community Edition as a vulnerability scanner to support small to medium sized enterprises with improving their IT security. This recommendation was now tested. Cyber security is often a tremendous challenge for small enterprises, which is why the FHNW looks into ways on how to support companies.

To evaluate the vulnerability scanner, it was installed and used in two private networks. While installing and using the scanner, user-friendliness was evaluated. Focus was to determine if the scanner was suitable for inexperienced users and if the tool could be a suitable option for the FHNW to offer vulnerability scans as a service.

The results of the testing provide a recommendation for the FHNW to use the Greenbone Community Edition as a tool to support companies in improving their IT infrastructure. The thesis also delivered a warning that the tool is not suited for users without IT knowledge. Further, the bachelor thesis contains guides on how to install the scanner, how to use the scanner and how to interprete the results.
