OpenVAS Scanner is the scanning engine of the Greenbone Community Edition and is also used in Greenbone Enterprise appliances. It performs vulnerability scans by running a set of Vulnerability Tests (VTs) that is updated and extended continuously through a feed.

The module is configured, built and installed with CMake and make, and the INSTALL.md file explains how to set up openvas and expose the scanner to other GVM modules. Release files are signed with the Greenbone Community Feed integrity key. Docker images are published to the Greenbone registry, and a fully containerized setup for the Community Edition is also provided.

The repository also contains a Rust project that aims to replace the existing scanner stack made up of openvas-scanner, ospd-openvas and notus-scanner, simplifying scanning by centralizing everything in one place; for now it uses openvas-scanner as the scan engine. The code is licensed under GPL-2.0. Anyone not comfortable building from source is pointed to the Greenbone Enterprise TRIAL virtual machine.
