About this Gig

A default Linux install is not a secure Linux install. Left alone, it's an easy target weak SSH config, no firewall discipline, no intrusion detection. I lock it down before that becomes your problem, based on CIS benchmark principles and scoped to be practical for a small server or homelab rather than enterprise-only bloat.


This is a defensive hardening pass, not a penetration test I'm closing the doors attackers usually walk through, not attempting to break in.


Here's what I offer:

  • Quick Setup: Hardening applied and verified in days, not weeks
  • Secure Access: SSH locked to key-only auth, no default ports left open
  • Threat Detection: fail2ban and log monitoring configured to catch and block abuse
  • Reduced Attack Surface: Unnecessary services disabled, firewall scoped to only what you need
  • Advanced Features: Full CIS-aligned hardening pass with written findings report (Premium)
  • Maintenance: Automatic security updates configured so patching doesn't fall on you
  • Support: Troubleshooting and guidance after delivery


Supported Platforms: Cloud VPS, Proxmox & VMware, NAS devices, home servers, any standard Linux distro (Ubuntu, Debian, etc.).
