The Brief

What Nuclei Community does

Nuclei is an open source vulnerability scanner from ProjectDiscovery that probes applications, infrastructure, cloud platforms and networks for exploitable flaws. It is built for security engineers, developers and organizations, bug bounty hunters and penetration testers. Scans run on simple YAML templates, each describing an attack route and its severity, drawn from a large community template library. The documentation names flexible target input such as URLs, IP ranges, ASN ranges and files, bulk and parallel scanning, custom templates, dynamic variables, CI/CD integration and configurable JSON or YAML output. The scanner itself is open source, while detailed reporting and two way ticketing integration are listed as features of the ProjectDiscovery cloud platform.
