Nessus was launched in 1998. It was initially developed as a free remote security scanner software, but was later developed by Renaud Deraison, developer of Nessus and owner of a company called Tenable Network Security. For personal use, the scanner software is free, but for commercial use, you only have to pay $ 1,200 per year for a single scanner. Nessus was originally designed to be able to scan user security. Like Nmap, which could do network discovery. Unlike Nmap, this tool is designed to identify vulnerabilities by scanning the network. In this tool, when checking some vulnerabilities, if Safe Mode is disabled, it may damage the system, so network administrators expose a system to scan before it enters the production cycle.If you are a security activist, you must have heard of Nessus Scanner, software that detects and reports vulnerabilities on various platforms such as network and operating system. Nessus is an open source software that provides security enhancements by identifying vulnerabilities. Nessus has a special language for assessing vulnerabilities called NASL, which stands for Nessus Attack Scripting Language, which security company executives can use NASL to customize scripts and assess security vulnerabilities.
