This document discusses ways to secure Node.js applications that use npm modules. It recommends setting up an npm registry mirror as a fallback in case of outages, caching modules locally and publishing privately, and monitoring for vulnerabilities using tools like npm audit, Snyk, and CVE databases. For production, it suggests using N|Solid to monitor applications for security vulnerabilities both at the top level and within nested dependencies. The overall message is that while npm is widely used, organizations should take steps to cover their applications and ensure the security of the dependencies and modules they use.
