Is NordVPN Leaking?
You think
"Huge network, famous brand — I’m covered."
The mirror
A big network only protects the traffic that actually goes through it.
Provider detection compares your exit network with the networks NordVPN is known to use. NordVPN may also rent servers elsewhere, so a real NordVPN connection can occasionally read as "a VPN, but not NordVPN". The test runs in your browser and asks a Cloudflare STUN server for your public address — exactly what any web page can do. We don't see, store or log the result.
Testing…
Three checks run in your browser: IP masking, WebRTC and timezone. DNS has its own test.
About NordVPN
NordVPN is based in Panama. It states a no-logs policy. Its apps are not fully open source. It supports the WireGuard protocol. These are the provider's public claims and basic facts, not a guarantee.
Worth knowing
In October 2019 NordVPN disclosed that a server at a third-party datacenter in Finland had been accessed without authorization in 2018; the company said no user data was affected.

How to fix NordVPN leaks
Turn on the kill switch
In the NordVPN app's settings, enable the kill switch (or its equivalent) so traffic stops if the tunnel drops instead of falling back to your normal connection.
Restrict WebRTC in your browser
Firefox: about:config → media.peerconnection.enabled → false. Brave: Settings → Privacy and security → WebRTC IP handling policy → "Disable non-proxied UDP".
Reconnect, then re-test
Reconnect NordVPN, make sure it is the connection this browser uses, and run the test again. A VPN only counts if the test says so.
Changed something? Prove it.
Re-run the test after every change — the verdict above updates in place.
Questions about NordVPN
Is NordVPN leaking my IP address?
Run the test above to see your real result. NordVPN can only protect the traffic it carries; a WebRTC leak or a timezone mismatch happens in the browser, outside the VPN's control.
How does this page know I am on NordVPN?
This page compares the network your connection exits from (its ASN) with the networks NordVPN is known to use — 1 verified so far. NordVPN may also rent servers on other networks, so a genuine NordVPN connection can occasionally show up as "a VPN, but not NordVPN".
Does NordVPN prevent WebRTC leaks?
Whether WebRTC leaks depends on your browser, operating system and VPN app settings together, which is why this page tests the real result instead of assuming. Restricting WebRTC in the browser removes the question entirely.
Where is NordVPN based?
NordVPN is based in Panama. Jurisdiction affects legal requests to the provider; it has no effect on whether your browser leaks.
