Why most zero-trust architectures fail at the traffic layer

What is often overlooked is how traffic enters and moves through the environment before those controls are applied.

The traffic layer includes ingress paths, load balancers, API gateways, TLS enforcement, request validation, and service-to-service communication. This is where trust is either established or assumed.

In several environments I have worked in, these gaps were not due to a lack of tools. They came from inconsistent ownership between networking, security, and application teams.
