Tenable advertises Nessus as the number one tool for vulnerability assessment, scanning for over 75,000 CVEs (Common Vulnerabilities and Exposures). Nessus is a vulnerability assessment tool made by Tenable, available as a free version, professional version, and expert version. There are outside repositories that can greatly increase the number of vulnerabilities Nmap can scan for, such as Vulners.

Nmap has a powerful scripting engine that includes scanners for a wide range of known vulnerabilities. It comes preinstalled on Kali Linux and is often the first tool penetration testers use to enumerate their target. It has the ability to discover hosts on a network and provide a wealth of information on them, including the hostname, operating system, open ports, running services and service versions, and more. Short for Network Mapper, Nmap is a free and open-source tool used for network discovery and security auditing.
