About this Gig

I am a Security Consultant with hands-on experience in Application Security, VAPT, and Debian/Ubuntu system hardening. This gig provides safe, realistic security improvements with none to minimal downtime.


I focus only on Debian-based systems so I can deliver high-quality, accurate hardening with predictable results.


What I can do (depending on package):

  • SSH hardening (disable root login, strengthen configs)
  • Firewall setup (UFW or iptables)
  • Fail2ban installation with basic jails
  • Nginx security headers (if Nginx is installed)
  • Basic malware or suspicious file checks
  • System update and patch review
  • Backup script setup (Premium)
  • File integrity monitoring (Premium)
  • Clear written report for all changes


Systems Supported:

  • Debian 10/11/12+, Ubuntu Server 18.04/20.04/22.04+


️What I do NOT offer (for transparency):

  • Deep forensic malware cleanup
  • Guaranteed unhackable servers
  • CentOS/AlmaLinux/Windows support
  • High-risk changes that can break your apps


What you get:

  • Safe, controlled security improvements
  • Automated scripts (Optional) or No risky commands
  • Short, clear documentation of all steps
  • Honest recommendations for anything outside scope


I am here to help for security-first hardening.
