Nessus is a proprietary vulnerability scanner developed by Tenable, Inc.
In 1998 Renaud Deraison created The Nessus Project as a free remote security scanner.
[2] On October 5 2005, with the release of Nessus 3, the project changed from the GNU General Public License to a proprietary license.
[3] The Nessus 2 engine and some of the plugins are still using the GNU General Public License, leading to forks based on Nessus like OpenVAS[2][4] and Greenbone Sustainable Resilience.
