#  Unified Security Across Private 5G and Public Cellular 

One SIM, one identity, one policy, whether the device is on private 5G or public MNO.

This demo shows how device identity and security policy travel with a device across networks. Built with Monogoto (MVNO/SIM provider) and Versa (SASE), a single eSIM profile lets a truck's router connect to an MNO network (like AT&T) outside a distribution center, then seamlessly roam onto the private 5G network once it enters.

The Versa SASE gateway enforces device identity and policy, and that policy travels with the device across both networks. A truck allowed to access warehouse apps like SAP but blocked from streaming stays governed by that same policy on the MNO network too. AMRs onboarded only with a Celona eSIM, by contrast, stay confined to the private network entirely, with no outbound internet access at all.

**Result:** a unified, end-to-end secure connectivity ecosystem, not just a device-level fix, where identity and policy consistently follow the device regardless of which network it's on.
