• Strong experience with F5 load balancers (LTM/GTM/ASM/AFM) and traffic management policies.
• Knowledge of Cisco ASA firewalls and other major vendor platforms (Juniper, Arista, etc.).
• Familiarity with zero‑trust access control solutions (ClearPass, Cisco ISE).
• Solid understanding of network protocols (TCP/UDP, IPv4/IPv6, BGP, OSPF, VXLAN, EVPN, IP Multicast).
• Experience with automation frameworks (Python, Ansible, Terraform, Go) for network security operations.
