About HardcoreDebug

Free tools and honest write-ups for engineers who troubleshoot networks, proxies and web apps for a living.

HardcoreDebug is a technical platform focused on troubleshooting, performance analysis and deep-dive debugging across modern network and security infrastructure. We turn messy, real-world issues into clear, repeatable guides that save engineers time and guesswork.

Everything here comes from hands-on work with enterprise technology: cloud security, zero-trust access, proxies, VPN and IPsec tunnels, and application delivery. Where we can, we include logs, captures and step-by-step fixes so you can reproduce and apply them in your own environment.

Why we built the tools

Existing tools usually show you what happened but not why. When you're deep in a tunnel or SSO failure at 2 AM, you need IPs, ports, redirect chains, timings and headers in one place, not spread across a dozen tabs. So we built that, and made it free.
