Overview In modern penetration testing, speed and accuracy are critical. Security researchers need tools that can quickly identify vulnerabilities across multiple targets without missing important issues. Nuclei is a powerful solution designed for automated vulnerability scanning using customizable templates. What is Nuclei? Nuclei is an open-source vulnerability scanner developed by ProjectDiscovery. It works by sending requests to a target and matching responses against predefined templates to detect security issues. Unlike traditional scanners, Nuclei is lightweight, flexible, and highly customizable. Why Nuclei is Important Nuclei has become widely used because it offers: Fast scanning performance Template-based detection Support for multiple protocols such as HTTP, DNS, and TCP Easy integration into automation workflows How Nuclei Works Nuclei operates using templates written in YAML format.
