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: Browser secure-DNS settings are a documented browser feature. Specific family-plan misconfiguration rate is not established.
Detection
The device’s system DNS is set to the family resolver, yet a browser’s secure-DNS setting is on and points elsewhere; the browser loads blocked destinations through the encrypted endpoint.
Fix (technical)
Review each browser the household uses: confirm whether secure DNS is on, where it points, and whether the browser exposes a managed setting. On managed devices, configure the browser’s policy to lock the resolver to the family one where the browser supports it.
Fix (relational)
Secure DNS is a privacy default for some browsers. Frame the review as a check-up rather than as evidence of evasion.
Residual risk
Browsers without a managed secure-DNS setting, or browsers that ship a new default after an update, may bypass the lock. The lock is per-browser, not per-device.
