- Configured Palo Alto PA-5410 and PA-3440 next-generation firewalls using Panorama for centralized policy enforcement and threat prevention profile application.
- Designed SD-WAN (Versa & Viptela), SD-LAN and WAN optimization technologies for efficient delivery of the application data across LAN and WAN.
- Worked on the installation and configuration of Aruba 207 series, 320 series wireless access points and their management through the Aruba ClearPass for the access control.
- Managed Palo Alto firewall performance and long-term stability through recurring policy audits, structured cleanup efforts, and optimization projects, eliminating redundant, shadowed, and overlapping rules across Panorama-managed firewall fleets.
- Worked closely with the security operations team to configure, troubleshoot, and optimize Fortinet FortiGate firewall environments, with a strong focus on IPS/IDS tuning, SSL inspection/decryption performance, and VPN policy enhancements.
- Managed FortiGate 1000F and 200F appliances via FortiManager, executing consistent security rule updates and NAT policy configurations across the enterprise environment.
- Configured Palo Alto PA-5260 and PA-3220 firewalls with App-ID and User-ID to restrict unauthorized internal and external traffic flows.
- Led PAN-OS upgrades (9.x–11.x) across PA-3000/5000 series, ensuring zero critical outages and maintaining security compliance.
- Engineered Layer 3–Layer 7 security policies using App-ID and User-ID, improving application visibility and strengthening access control.
- Configured Cisco Firepower FTD (1150/2130) NAT and security policies via FMC, enhancing segmentation and threat protection.
- Performed deep-dive packet capture and traffic-flow analysis, accelerating root-cause identification and reducing incident resolution time.
- Implemented Cisco Firepower 1140 and 1120 appliances, updating policy sets to mitigate signature-based network threats.
- Troubleshooted complex LAN/WAN infrastructure that include routing protocols EIGRP, OSPF & BGP and MPLS.
- Built site-to-site IPSec VPNs over Frame-relay & MPLS circuits on various models of cisco routers (100, 4000 and 8000 series).
- Managed VXLAN and EVPN configurations to expand internal data center network capacity.
- Implemented IGRP and EIGRP protocols across legacy infrastructure components to maintain connectivity.
- Optimized MPLS WAN path selection by modifying route metric settings to prioritize latency-sensitive traffic.
- Balanced incoming traffic using Citrix load balancers, creating virtual server VIPs and backend server pools.
