"7,000+ community templates scanning for CVEs, misconfigs, exposed panels, and default credentials."
Nuclei is a template-based vulnerability scanner maintained by ProjectDiscovery. Each template is a YAML file describing how to detect a specific vulnerability — a CVE, a misconfiguration, an exposed admin panel, a default password. The community maintains thousands of these templates and they're updated continuously as new vulnerabilities are discovered.
PTK runs nuclei with the full template library against your targets. You can filter by severity (only run critical and high templates, skip info) and set a rate limit to avoid overwhelming the target or triggering WAFs. Nuclei finds things that generic scanners miss because its templates are written by security researchers who have actually exploited these vulnerabilities in the wild.
