Nuclei

Nuclei is a high-performance vulnerability scanner driven by simple YAML templates. Templates describe detection scenarios that reproduce the real steps needed to confirm a vulnerability, which reduces false positives, and a large template library is contributed by thousands of security professionals to cover trending vulnerabilities.

Nuclei scans applications, cloud infrastructure and networks, and supports protocols such as TCP, DNS, HTTP, SSL, WHOIS, JavaScript and code. It processes scans in parallel with request clustering, can be integrated into CI/CD pipelines for vulnerability detection and regression testing, and reports to tools such as Jira, Splunk, GitHub, GitLab and Elastic.

Nuclei is developed by ProjectDiscovery, written in Go and distributed under the MIT licence; it is actively maintained on GitHub, and ProjectDiscovery also offers a commercial platform.
