This applies equally to the edge tier (Cloudflare), security platforms (Zscaler ZIA/ZPA, ZTNA policies, next-gen firewalls), the cloud network fabric (Transit Gateway, Cloud WAN, VPCs, Route53, IPAM), and increasingly the Kubernetes and service-mesh layer. Operate and extend our multi-account AWS Landing Zone - Cloud WAN segmentation, Transit Gateway peering, IPAM-driven CIDR allocation, shared private DNS, cross-account telemetry pipelines.
