Nuclei Scanner

Overview

Nuclei is a fast, template-based vulnerability scanner by ProjectDiscovery. Instead of running monolithic scanners, Nuclei uses YAML templates — each one checks for a specific vulnerability, misconfiguration, or exposure. Community maintains 8000+ templates covering CVEs, default credentials, exposed panels, misconfigurations, and more. Runs in CI, scripted pipelines, or manual assessments.

When to Use

• Security assessment of web applications before deployment
• Checking infrastructure for known CVEs and misconfigurations
• Continuous security scanning in CI/CD pipelines
• Bug bounty reconnaissance and vulnerability discovery
• Compliance checks (exposed admin panels, default credentials, SSL issues)
