How NoorI Prevents VPN and DNS Bypass Attempts
The common ways people try to route around a filter, and which ones NoorI actually stops.

The obvious attempt: changing DNS manually
The first thing most people try is manually pointing their device's DNS settings at a public resolver like 8.8.8.8, bypassing whatever DNS server is normally used.
How NoorI blocks it
NoorI automatically pushes a rule to every enrolled device that denies attempts to override DNS settings while the WARP tunnel is active — the override attempt itself gets blocked at the same network layer everything else does, so it doesn't require the device to be monitored for the change after the fact.
The harder case: a separate VPN app
Being direct about a real limit — if someone installs an entirely separate VPN app (unrelated to NoorI) and connects through it, that traffic leaves the device through a different tunnel that NoorI's Gateway never sees. No DNS-level filter, from any vendor, can see traffic that never asks it a question in the first place. For a device you fully control, pairing this with an OS-level app restriction (e.g. iOS's "Don't Allow App Installation") closes that gap.
Why incognito or private browsing doesn't help
Private browsing only clears local history on the device — it does not change how DNS queries are resolved. NoorI filters at the network layer regardless of which browser mode is being used.
What we'd actually recommend
Combine NoorI's network-level filtering with a device-level app restriction for anyone likely to try a workaround, and keep an eye on the Activity tab — a device that goes suspiciously quiet is a more reliable signal than trying to catch every possible bypass technique individually.
