Enterprise Wi‑Fi Security
Support rollout and configuration of secure enterprise Wi‑Fi
Design SSIDs, segmentation, and authentication (including 802.1X)
Troubleshoot performance, coverage, and connectivity issues
Cross‑Domain Troubleshooting
Diagnose complex issues across cloud, on‑prem, and remote environments

Ideal Candidate
Strong hands‑on experience with Zscaler ZIA & ZPA
Solid operational knowledge of FortiGate firewalls
Experience with enterprise Wi‑Fi security
