About RouteHarden

RouteHarden is a publication and consultancy focused on the engineering side of network security: how to build, harden, and operate networks that are private by design.

We cover four clusters: network hardening (kernel, firewall, sysctl), anonymity engineering (DNS, IPv6, fingerprinting, traffic analysis), self-hosted privacy (WireGuard, Tailscale, Headscale, sing-box), and corporate networks (zero-trust, mesh, secure access).

Everything we publish is technical, opinionated, and tested. No affiliate-bait listicles. No "best VPN of 2026" SEO sludge.

If you need someone to audit your network architecture, design a secure overlay for your team, or harden a self-hosted setup, we take consulting clients.
