Nessus

Nessus is a software tool designed to identify system vulnerabilities through automated point-in-time assessments. It is capable of detecting software defects, missing patches, malware, and misconfigurations across a wide range of operating systems, devices, and applications. This comprehensive scanning ability allows for a thorough understanding of system vulnerabilities and potential threats.

The software employs several vulnerability scoring systems such as CVSS v4, EPSS, and Tenable’s VPR. These systems facilitate the prioritization of vulnerabilities, aiding in the planning and execution of remediation efforts. Nessus also offers a resource center equipped with actionable advice and guidance. This feature serves as a useful tool for both experienced staff and those less familiar with security protocols, providing clear directions for the next steps in addressing identified vulnerabilities.
