fwiw ~ as per Norton Chat:

In v24+, a Private network may switch to Public if the device fails trust checks (like losing compliance), if there’s a mismatch in network profile, or due to admin policy overrides. It can also happen after network changes, system reboots, or updates that reset trust validation.

In v24+, a Public network may switch to Private if the device passes trust checks (e.g. becomes compliant or domain-joined), matches a trusted network profile, or receives an admin policy update that reclassifies it. It can also happen after reconnecting to a known secure network or post-validation.

Connecting to a VPN can trigger v24+ to reclassify a Public network as Private, especially if the VPN is recognized as secure or matches a trusted profile. This is because VPNs often route traffic through a known, controlled environment—meeting trust criteria.

fwiw ~ as per Norton Chat:
In v24+ we have the option of Private and Public network.
In v24+ Private network is the same as v22 Full Trust

In v24+, setting the network to Private network functions similarly to Full Trust in v22, and Device Trust behaves the same way as it did in v22 as well.

In v24+, the Device Trust settings are designed to mirror the behavior from v22, but with a few enhancements for clarity and control.

In v22, you could configure Device Trust at a per-user level, allowing for more granular control—like enabling trust for specific users or allowing overrides.

In v24+, Device Trust is still a feature, but it’s no longer a separate toggle. Instead, it’s automatically enforced when a network is set to Private. This means only trusted, compliant devices can access resources—just like Full Trust in v22. The shift makes trust enforcement simpler and more secure.
