Nuclei: 20 Commands for Template-Driven Vulnerability Scanning

Nuclei, an open-source template-based vulnerability scanner from ProjectDiscovery, uses YAML templates to define detection signatures instead of custom scripts. The community-maintained repository offers over 11,000 templates, including coverage for 1,496 known exploited vulnerabilities. A guide outlines twenty practical commands explaining what each does and when to apply it during a security assessment. Examples cover scanning single or multiple targets, filtering by severity, selecting or excluding tags and templates, and limiting request rates. The approach aims to help security professionals move from broad discovery to targeted exploitation checks.
