That’s a VPN: one key, and it opens every door in the building, no matter who’s holding it or where they’re standing.
ZTNA works differently. Everyone still gets in, but their card only opens what their job actually touches. The receptionist’s login reaches the scheduling system. It stops there. Sales will only reach their parts of the network, never able to reach operations.
ZTNA helps secure paths to your network.
Picture that receptionist’s laptop getting compromised on coffee shop wifi. A VPN just hands over the master key to the whole building while ZTNA gives up one door.
We think most offices are still handing out master keys, and calling it convenient until one ends up in the wrong hands.
The numbers below don’t lie.
Numbers like that don’t happen because small offices are careless, they happen because doors get left wide open. Old accounts are still active. People have more access than they need and nobody’s gone back to check the locks.
Moving to ZTNA can be done gradually. Most organizations start with a small group of users or applications, test the setup, and then expand the rollout in stages. That gives the IT team time to work through any issues before moving everyone over.
You also don’t have to replace everything at once. A phased rollout lets you keep the existing VPN in place while you move users and applications to ZTNA, then retire the VPN as coverage expands.
