- nuxt-security - 🛡 Security Module for Nuxt based on OWASP Top 10 and Helmet.
- reporting-api - Setup and collect CSP, Reporting API v0 and v1 reports to reliabily parse them to be processed by the user
- New dependencies advisor - GitHub Action adding comments to pull requests with package health information about newly added npm dependencies.
- OpenSSF Scorecard Monitor - Simplify OpenSSF Scorecard tracking in your organization with automated markdown and JSON reports, plus optional GitHub issue alerts.
- 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.
- tslint-plugin-security - TSLint 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.
- safe-regex - detect potentially catastrophic exponential-time regular expressions by limiting the star height to 1.
- vuln-regex-detector - This module lets you check a regex for vulnerability. In JavaScript, regular expressions (regexes) can be "vulnerable": susceptible to catastrophic backtracking. If your application is used on the client side, this can be a performance issue. On the server side, this can expose you to Regular Expression Denial of Service (REDOS).
- git-secrets - Prevents you from committing secrets and credentials into git repositories.
- DevSkim - DevSkim is a set of IDE plugins and rules that provide security "linting" capabilities. Also has support for CLI so it can be integrated into CI/CD pipeline.

- NodeJSScan - A static security code scanner for Node.js applications. Including neat UI that can point where the issue is and how to fix it.
- NodeSecure CLI - Node.js CLI that allow you to deeply analyze the dependency tree of a given npm package or a directory.
- Trust But Verify - TBV compares an npm package with its source repository to ensure the resulting artifact is the same.
- lockfile-lint - lint lockfiles for improved security and trust policies to keep clean from malicious package injection and other insecure configurations.
- pkgsign - A CLI tool for signing and verifying npm and yarn packages.
- semgrep - Open-source, offline, easy-to-customize static analysis for many languages. Some others on this list (NodeJSScan) use semgrep as their engine.
- npm-scan - An extensible, heuristic-based vulnerability scanning tool for installed npm packages.
- js-x-ray - JavaScript and Node.js SAST scanner capable of detecting various well-known malicious code patterns (Unsafe import, Unsafe stmt, Unsafe RegEx, encoded literals, minified and obfuscated codes).
- cspscanner - CSP Scanner helps developers and security experts to easily inspect and evaluate a site’s Content Security (CSP).
- eslint-plugin-anti-trojan-source - ESLint plugin to detect and prevent Trojan Source attacks from entering your codebase.

- data-guardian - data-guardian is a tiny, highly customizable lib which can mask sensitive data in arbitrary entities and can help with OWASP Protect Data everywhere.
- pug-plugin-trusted-types - Pug template plugin makes it easy to securely compose HTML from untrusted inputs and provides CSP & CSRF automagic.
- safesql - A tagged template (
mysql`...`) that understands Postgres's & MySQL's query grammar to prevent SQL injection. - sh-template-tag - A tagged template (
sh`...`) that understands Bash syntax so prevents shell injection.
