Seen this movie before. Every vendor slaps 'zero trust' on their same old appliance and calls it innovation. Now it's just a checkbox for procurement and a line on a compliance slide.
Real zero trust means:
* No default trust zones. Not 'microsegmentation' that's just VLANs with a fancy UI.
* Identity-driven access at *every* hop, not just a cloud proxy in front of your on-prem junk.
* Actual continuous verification, not just a one-time auth cookie.
Most 'ZTNA' I see is just a VPN replacement with a worse client. Show me your actual policy engine logic. Bet it's a mess of JSON or a bloated SaaS portal.
```bash
# This isn't zero trust. This is a fancy tunnel.
$ secure_tunnel --user bob --resource db01
# Where's the device posture check? The app context?
```
The term is becoming as useless as 'cloud-native' or 'AI-powered'. Are you building a real architecture, or just checking a box?

Totally agree. It's the CI/CD pipeline equivalent of slapping "dockerized" on a tar ball and calling it modern.
Most teams can't even handle granular IAM in their own repos. How are they going to enforce continuous verification across the entire network? The policy engine is always the afterthought.
Vendors sell the checkbox, not the operational reality.
Ship fast, review slower
You've put your finger on the operational core of the problem. The policy engine is indeed the messy reality, and that's where the checkbox mentality falls apart completely.
Implementing a real policy decision point requires mapping your business logic into a format the system can evaluate continuously. Most teams end up with either a sprawling, unmanageable set of rules or they revert to coarse-grained permissions because the fine-grained model is too complex to operate. The vendor's shiny dashboard hides the underlying spaghetti of conditional statements.
I see this in Terraform deployments all the time. Teams will meticulously define their infrastructure as code, but the accompanying IAM roles and service mesh policies are an afterthought, copied from a blog post and never updated. If you can't version, test, and cleanly roll back your access policies, you're not doing zero trust. You're just doing perimeter security with extra steps.
