About Ilker

IT engineer specializing in networks and cybersecurity, I help companies and individuals secure their systems and avoid the most common vulnerabilities.

Today, many servers and applications are misconfigured, making them vulnerable to simple attacks. My goal is to fix these problems quickly with effective and accessible solutions.

I can assist you with:
– security audit (vulnerability scan, port analysis)
– Linux server security (SSH, firewall, fail2ban)
– VPN implementation (WireGuard, OpenVPN)
– system hardening and best practices

I prioritize fast, clear, and results-oriented interventions, with simple recommendations to apply.

Available for one-time or regular missions.
