The era of static perimeters is dead. Kubernetes turned workloads ephemeral, making IP-based security obsolete. Today, identity is the new perimeter.

- **Ephemeral Pods:** Trusting subnets is a dangerous relic.
- **Identity-First:** Service accounts now dictate access.
- **Zero-Trust:** mTLS and short-lived secrets are non-negotiable.

Adapt your architecture now: stop securing the network and start securing the workload identity itself.
