OpenVAS

OpenVAS is an open-source full-featured vulnerability scanner developed and maintained by Greenbone Networks that performs authenticated and unauthenticated security testing across network infrastructure, servers, workloads, and devices using a continuously updated vulnerability feed with over 100,000 tests to identify security exposures, misconfigurations, and compliance issues. The platform supports various high-level and low-level internet and industrial protocols with performance tuning for large-scale scans, providing comprehensive vulnerability detection with severity-based risk scoring to enable organizations to proactively discover and remediate security weaknesses before they can be exploited by attackers.
