About Abdullah Ansari
I’m an Infrastructure Engineer with strong hands-on experience in network, security, and enterprise infrastructure operations. I specialize in designing, managing, and optimizing FortiGate and Juniper firewall environments, including security policies, NAT, VPNs, HA, and SD-WAN deployments.I have practical expertise in LAN/WAN architectures, routing and switching (BGP, OSPF, VLANs, PBR, ACLs), and end-to-end IPsec & remote access VPN implementations. I’ve worked extensively on Fortinet and FatPipe SD-WAN, ensuring high availability, SLA-based routing, traffic optimization, and minimal downtime.Beyond networking, I bring solid system administration experience—managing Active Directory, Zimbra Mail Server, Windows & Linux servers, endpoint security (Trend Micro), and enterprise monitoring using Checkmk, OpManager, PRTG, and NetFlow.I’m comfortable handling 24×7 infrastructure operations, firewall audits, firmware upgrades, change management, vendor coordination, and critical incident troubleshooting. I focus on building secure, scalable, and reliable infrastructure that supports business continuity and growth.
