OpenVAS review | GadgetMasti

Open Vulnerability Assessment System (or OpenVAS for short) is a full-featured, cross-functional, open-source web security scanner (opens in new tab) that started when Nessus stopped being an open source software and turned into a commercial security solution.

Once called GnessUs and launched as a spin-off of Nessus, it still uses numerous plugins written in Nessus Attack Scripting Language (NASL). Eventually, in 2006, OpenVAS would become the enterprise-level tool we know today.
