As organizations increasingly rely on web applications and infrastructure, the need for effective security testing has become crucial. One of the most efficient and effective ways to identify security vulnerabilities is by using template scanners, which are automated tools that scan for known vulnerabilities in web applications and infrastructure. One such tool is Nuclei, a YAML-based template scanner. I´ve tested this tool a lot and my conclusion is that it´s great when used correctly!
What is Nuclei? Link to heading
Nuclei is a fast, flexible and open-source template-based scanner that allows for quick and efficient vulnerability scanning of web applications and infrastructure. It is built on top of the popular Go programming language, making it lightweight and easy to use. Nuclei uses YAML-based templates to define the rules for vulnerability scanning, allowing for easy customization and modification of the scanning process.
