Hands-on experience with Zscaler (ZPA/ZIA) or comparable Zero Trust platforms
Proven success migrating legacy VPNs to Zero Trust, cloud-delivered access solutions
Deep expertise in ZTNA design, implementation, and Zero Trust principles (least privilege, continuous verification, no implicit trust)
Experience designing application segmentation and identity-based access policies
Strong knowledge of traffic steering, split tunneling, and secure access routing (ZVPN architectures)
Experience with load balancing, gateways, and access control layers
Advanced troubleshooting across network layers (L3–L7)
Familiarity with hybrid environments (on-prem, cloud, SaaS)
Ability to optimize latency, performance, and user experience in ZTNA environments
Experience with high availability, disaster recovery, and failover strategies in global, always-on environments
Experience with network automation tools (Python, Ansible, APIs)
Familiarity with endpoint management and deployment tools (Intune, SCCM)
Strong understanding of identity providers (Azure AD / Entra ID), SSO, and conditional access
