VPN / Proxy Detection

Websites use several signals to guess whether a visitor is behind a VPN or proxy. This test checks the same indicators for your connection and explains each one.

Tool status: Functional with limitations Works, but there are technical limits explained on the page.

VPN & proxy indicators

Runs in a few seconds. Uses your IP information, browser time zone and WebRTC.

What this tool can and cannot do

There is no definitive way to detect a VPN. Commercial detection services use large paid databases of known VPN exit addresses. We use transparent heuristics instead, so results are indications, not proof – a business network can look like a VPN, and some residential VPNs look like normal home connections.

Data sources: IPinfo Lite (or registry fallback) · Google STUN server (WebRTC)

Understanding the results

Each indicator is independent. Several indicators together make VPN or proxy use more likely. If you want your VPN to be less detectable, the time-zone and WebRTC indicators are the ones you can fix yourself.

Troubleshooting

  • Time zone mismatch: some VPN apps can set your browser's time zone, or you can change your system time zone to match the VPN location.
  • WebRTC exposure: enable your VPN's WebRTC protection or use the WebRTC Leak Test for details.
