HamidReza Khazaie

I am a Senior Network Security Engineer with 12+ years of experience designing, securing, and operating enterprise networks.

My strongest work is around firewall architecture, firewall migration, VPN, SD-WAN, segmentation, high availability, and secure network operations. I have hands-on experience with FortiGate, Cisco ASA/Firepower/FTD, Sophos, MikroTik, Cisco routing and switching, and AWS security services.

In recent roles, I have worked on FortiGate HA deployments, Cisco ASA to FortiGate migrations, site-to-site and SSL VPN design, AWS security posture, Cloudflare ZTNA/WAF/CDN, Cisco ISE 802.1X, vulnerability management, and SOC 2 technical evidence support.

I focus on practical security: clean firewall policies, controlled changes, rollback planning, clear documentation, and solutions that operations teams can actually maintain.

Open to senior network security, firewall engineering, cloud security operations, and infrastructure security roles. Also available for freelance firewall migration, VPN, and security hardening projects.

Available for: Remote, hybrid, freelance, and project-based security work
Location: Italy, open to EU remote opportunities
