VPN Leak Tests by Provider
Pick your VPN. Each page runs the same checks — IP masking, WebRTC, timezone — and also checks that you are really connected to that provider. Not on the list? Test any VPN →
Is Proton VPN leaking?
You think: Swiss jurisdiction + no logs = untouchable.
The mirror: Jurisdiction doesn’t help if your browser hands out your IP anyway.
Is Mullvad leaking?
You think: Mullvad doesn’t even ask for my email — I’m anonymous.
The mirror: An anonymous account means little if a web page can read your real address from the browser.
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.
Is ExpressVPN leaking?
You think: Premium VPN, so premium protection.
The mirror: Price doesn’t patch a leak. Your browser answers WebRTC questions on its own.
Is Surfshark leaking?
You think: One subscription, every device protected.
The mirror: Every browser decides for itself what to reveal — each device needs its own check.
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.
Is Private Internet Access leaking?
You think: Years of use and nothing has ever gone wrong.
The mirror: Leaks are silent. Nothing visibly breaks when one happens.
Is Windscribe leaking?
You think: The firewall is on, so I’m fine.
The mirror: A firewall guards the tunnel. WebRTC and your timezone live in the browser.
Is IVPN leaking?
You think: A privacy-first provider — nothing to worry about.
The mirror: The provider can do everything right and your browser can still say too much.
These pages do not check DNS — the DNS Leak Test does. Provider facts on each page are public claims, not guarantees.
