VPS security hardening is the difference between a server that gets compromised within hours of provisioning and one that stays secure for years. This complete checklist covers SSH hardening, fail2ban, UFW, CrowdSec, SSL, and web security headers.

Vulnerable npm packages are responsible for some of the most damaging supply chain attacks in recent years. This guide explains how CVEs get into your dependencies, how to use npm audit effectively, when upgrading is the right call, and how to automate security scanning so you're not caught off guard.
