Enterprise & On-Prem Network Security: Own firewalls, segmentation and microsegmentation, wireless, DNS, VPN/ZTNA, and device hardening across a growing multi-site footprint, including corporate offices, data centers, and on-prem and production environments (i.e., Palo Alto, Cisco, Aruba; GlobalProtect, Tailscale/WireGuard, IPsec). Move the enterprise toward zero-trust access and retire flat-network and legacy-VPN patterns.
