Nsat is a fast, stable bulk security scanner designed to audit remote network services and check for versions, security problems, gather information about the servers and the machine, and much more. Unlike many other auditing tools, nsat can collect information about services independently of vulnerabilities, which makes it less dependent on frequent updates as new vulnerabilities are found.
