I help organizations deploy, migrate, optimize, and troubleshoot Zscaler environments. With 4+ years of hands-on NSEC experience, I specialize in Zscaler Internet Access (ZIA), Zscaler Private Access (ZPA), Zscaler Client Connector (ZCC), Zscaler Branch Connector (ZBC), and Zscaler Digital Experience (ZDX). My experience includes with end-to-end implementation, including architecture planning, initial configuration, policy creation, traffic forwarding, identity integration, testing, troubleshooting, and documentation. I have managed Zscaler Client upgrade rollout across 200,000+ endpoints, migrating Microsoft 365 traffic from legacy Blue Coat Proxy to ZIA, and ZPA deployments to replace Cisco AnyConnect VPN.
