Why this matters:How to recognise this workaround on your side, and what closes it on your side — without telling you how to do the workaround.
How common it is: Modern VPN protocols (for example WireGuard, OpenVPN variants, and obfuscated transports) are documented. Specific use among minors to evade parental controls is not established.
Detection
A classifier marks a flow as probable VPN but cannot name a protocol; the device shows an active tunnel that the router cannot identify.
Fix (technical)
Treat classifier output as one signal. Confirm the tunnel on the device by reading its VPN settings; rely on the device-side and account-side controls for enforcement rather than on the network-side classification alone.
Fix (relational)
Treat a probable-VPN signal as a reason to look at the device, not as proof. The conversation about what apps are on the phone is the load-bearing conversation.
Residual risk
False positives and false negatives remain. A flow that looks like a VPN may not be one; a flow that does not look like a VPN may still be one.
