OpenVAS (Open Vulnerability Assessment Scanner, originally known as GNessUs) is the scanner component of Greenbone Vulnerability Management (GVM), a software framework of several services and tools offering vulnerability scanning and vulnerability management.
All Greenbone Vulnerability Management products are free software, and most components are licensed under the GNU General Public License (GPL). Plugins for Greenbone Vulnerability Management are written in the Nessus Attack Scripting Language, NASL.
Greenbone Vulnerability Manager began under the name of OpenVAS, and before that the name GNessUs, as a fork of the previously open source Nessus scanning tool, after its developers Tenable Network Security changed it to a proprietary (closed source) license in October 2005. OpenVAS was originally proposed by pentesters at SecuritySpace, discussed with pentesters at Portcullis Computer Security and then announced by Tim Brown on Slashdot.
There is a daily updated feed of Network Vulnerability Tests (NVTs) – over 50,000 in total (as of July 2020).
The OpenVAS protocol structure aims to be well-documented to assist developers. The OpenVAS Compendium is a publication of the OpenVAS Project that delivers documentation on OpenVAS.
