On-Device
Policy Enforcement
Who can get in is decided on your phone, inside a sealed hardware vault — not by asking a distant server. No round trip, no middleman to wait on or hack.
The rule lives where you live
Traditionally, when you try to enter an app or service, a central server decides “yes” or “no”. That means a journey: your phone asks, the data travels, someone else decides, the answer comes back. dZTA ends that journey entirely.
The old way: ask permission
Your phone sends your request to a central server. That server consults a database full of rules and records about you, decides, and replies. It's slow, it exposes your data to a third party, and that server becomes a single target — compromise it and everything falls.
The dZTA way: decide at the door
Your phone holds its own copy of the rules, locked inside a hardware vault. When you want in, it checks the rules on the spot — instantly, privately, with nothing sent anywhere. Only a small proof of "allowed" ever leaves the device.
What you get
A decision that feels instant, because there's no long trip to a server and back. No middleman that can spy on you, slow you down, or be hacked. And no single server holding the keys to everyone's access.
A decision, minus the round trip
Four short steps happen on your device in the time it takes to blink.
You ask to enter
You tap to access a service. Nothing is sent yet — the request is still sitting safely on your device.
The vault checks the rules
Your phone's sealed hardware compartment — a locked room your phone's normal software can't touch — checks whether you're allowed in.
It stamps a proof
Instead of sending who you are or what you have, it produces a tiny mathematical proof: "this person is allowed." No personal details inside.
You're in
The proof is checked in milliseconds. You get access before a trip to a distant server could even begin.
Access decided at the door.
