Openvas
OpenVAS is a full-featured vulnerability scanner. Its capabilities include unauthenticated testing, authenticated testing, various high level and low level Internet and industrial protocols, performance tuning for large-scale scans and a powerful internal programming language to implement any type of vulnerability test.
The scanner is accompanied by a vulnerability tests feed with a long history and daily updates. This Greenbone Community Feed includes more than 50,000 vulnerability tests.
The scanner is developed and maintained by Greenbone Networks since 2009. The works are contributed as Open Source to the community under the GNU General Public License (GNU GPL).
Greenbone develops OpenVAS as part of their commercial vulnerability management product family "Greenbone Security Manager" (GSM). OpenVAS is one element in a larger architecture. In combination with additional Open Source modules, it forms the Greenbone Vulnerability Management solution. Based on this, the GSM appliances use a more extensive feed covering enterprise needs, a GVM with additional features, appliance management and a service level agreement.
