Static Code Analysis
- eslint-plugin-security - ESLint rules for Node Security. This project will help identify potential security hotspots, but finds a lot of false positives which need triage by a human.

- cspscanner - CSP Scanner helps developers and security experts to easily inspect and evaluate a site’s Content Security (CSP).
Dynamic Application Security Testing
