OpenVAS

OpenVAS is a powerful, open-source vulnerability scanner designed for security professionals and system administrators to identify security weaknesses across diverse network infrastructures. It performs both authenticated and unauthenticated testing, providing deep visibility into potential threats across numerous internet protocols. As the foundational engine for Greenbone’s commercial offerings, it delivers enterprise-grade scanning capabilities without licensing costs. Its primary differentiator is the combination of a robust, community-driven vulnerability feed with a highly flexible architecture, making it an essential tool for proactive security assessment and risk management.
