Abdul Rahman Zainal

I'm delivering end-to-end network security projects for multinational customers at Orange Business Malaysia, seconded to Orange Cyberdefense Belgium. I lead Fortinet FortiGate deployments, migrations, upgrades, hardware refreshes, and HA implementations.

I've designed routing and switching solutions using OSPF, BGP, VRRP, and HSRP, while configuring SD-WAN, IPsec VPN, SSL VPN, security policies, NAT, application control, and web filtering. I also automate deployments with Python and Linux scripting, produce HLDs, LLDs, and runbooks, and mentor junior engineers through delivery.

Previously at VADS, I deployed and migrated FortiGate, Cisco ASA, Juniper SSG/SRX, SonicWall, and Cisco PIX firewalls for managed security services. My work included Active Directory web-filtering integration, Cisco IronPort migrations, IPS signature baselining, technical workshops, and low-level design documentation.

Across OFISGATE, IBIL, TIME dotCom, and Secure-IP, I've performed security assessments, hardened cloud servers, implemented SIEM, backup, logging, AAA, IDS, and Linux firewall platforms, and supported security incident handling for ISP environments.
