Is CyberGhost Leaking?
You think
"I clicked Connect, so I’m hidden."
The mirror
Connected is not the same as covered. Check what the browser still says.
Provider detection for CyberGhost is limited: there is no verified list of its networks yet, so a VPN will be reported as detected but not confirmed as CyberGhost. 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 CyberGhost
CyberGhost is based in Romania. 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.

How to fix CyberGhost leaks
Turn on the kill switch
In the CyberGhost 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 CyberGhost, 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 CyberGhost
Is CyberGhost leaking my IP address?
Run the test above to see your real result. CyberGhost 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 CyberGhost?
We do not have a verified network list for CyberGhost yet, so this page can tell you whether you are on a VPN or hosting network at all, but it cannot confirm which provider it is.
Does CyberGhost 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 CyberGhost based?
CyberGhost is based in Romania. Jurisdiction affects legal requests to the provider; it has no effect on whether your browser leaks.
