A Multi-Cloud Zero Trust Lab, Built in Terraform
How I built a repeatable AWS, Azure and Google Cloud lab to explore Cloudflare Access, Gateway, WARP routing, device posture and external evaluation as one integrated Zero Trust system.

Cloudflare DNS Ad Blocking with Terraform
I used Terraform to fetch public domain feeds, turn them into Cloudflare Zero Trust lists and enforce them with a Gateway DNS policy that remains reviewable as code.

Zero Trust Allow Lists with Workers KV
A small Cloudflare Worker can provide a controlled front end for Gateway allow-list changes while KV supplies recovery, synchronization and operational visibility.

Resolve Gateway Rule IDs Before Showing Them
Cloudflare Gateway can provide a rule ID to a custom block page, but resolving that UUID to the rule name makes support diagnostics much more useful.

Gateway Block Pages Need Policy Context
A CF-Ray header alone does not prove a request came from Gateway, so my Worker requires Gateway-specific query context before rendering diagnostic output.

Turning Remote Feeds into Terraform Policy Inputs
An HTTP data source can retrieve an external domain feed, but the useful pattern is to validate and normalize it before Terraform materializes enforcement objects.
