Nuclei

Nuclei transforms vulnerability scanning by leveraging a global community of security researchers who contribute detection templates written in simple YAML. Instead of maintaining complex scanning logic, you can tap into thousands of pre-built templates that identify everything from CVEs to misconfigurations across your entire attack surface.

Built with Go for exceptional performance, Nuclei excels at scanning large-scale infrastructure without the overhead of traditional security tools. The YAML-based DSL makes it remarkably easy to write custom detection rules, allowing security teams to quickly respond to emerging threats by creating and sharing templates within hours of disclosure.

What sets Nuclei apart is its versatility—it seamlessly scans web applications, REST APIs, network services, DNS records, and cloud configurations from a single tool. The community-driven template library grows daily, ensuring you're always protected against the latest vulnerabilities without waiting for vendor updates.

Whether you're running security audits, monitoring production systems, or integrating automated scanning into CI/CD pipelines, Nuclei provides the speed and flexibility needed for modern DevSecOps workflows. Its lightweight architecture and extensive template ecosystem make it an essential tool for proactive security testing.
