How to confirm a WebRTC leak
You can confirm a WebRTC leak by following these steps:
- Disconnect from your VPN.
- Open a new browser window and look up your IP address.
- Write down all public IP addresses you see.
- Close the page.
- Reconnect to your VPN and reopen the page.
- If you see any of the same public IP addresses once reconnected to your VPN, you have a leak. If not, your IP address is secure.

What is WebRTC?
WebRTC (Web Real-Time Communication) is a browser protocol that enables real-time communication, such as video calls, voice chats, and file sharing, directly between devices without needing intermediary servers.
It establishes a peer-to-peer connection, ensuring low latency and secure data exchange. Think of it as a shortcut allowing your browser to connect directly with other devices, bypassing longer server routes. This technology is used in applications like Google Meet, Zoom, and WhatsApp Web, providing communication directly from the browser.
What is a WebRTC leak?
A WebRTC leak is a security vulnerability in which your browser exposes your real IP (Internet Protocol) address despite being connected to a VPN (Virtual Private Network). This leak occurs because WebRTC can bypass the VPN's encrypted tunnel, revealing your actual location and identity to websites or online services.
Why should I test for WebRTC leaks?
Because WebRTC leaks can expose your personal information, causing many risks:
Revealed IP address
Exposed location
Compromised anonymity
Targeted tracking
Targeted attacks
Data selling
What causes WebRTC leaks?
Default browser settings
VPN without WebRTC leak protection
Browser or VPN settings issues

How do I test for WebRTC leaks?
To test for WebRTC leaks, use an online WebRTC leak checker tool. Connect to your VPN and visit the tool’s website to see if your real IP address is exposed.
You can perform the test with and without the VPN and compare the results.
How do I disable WebRTC on my browser?
To disable WebRTC on your browser, adjust the settings or use a browser extension designed to block WebRTC.
For Firefox, you should go to Advanced Settings and search for WebRTC. Double-click the setting to change its value to false.
For Safari, you can disable WebRTC by enabling the Develop menu. Once the Develop menu is visible, navigate to WebRTC and uncheck it to disable.
There isn’t a built-in option to disable WebRTC directly for browsers like Chrome, Edge, and Opera. Instead, you could use browser extensions to manage WebRTC settings.
