WebRTC Leak Tester

What is a WebRTC Leak?

WebRTC (Web Real-Time Communication) is a powerful technology that enables direct audio and video communication within web browsers without the need for intermediate servers. While beneficial for applications like video conferencing (Google Meet, Zoom web client), it can inadvertently reveal your real IP address to websites, even when you are using a VPN or proxy. This security vulnerability is known as a WebRTC Leak.

A WebRTC leak occurs when the browser's STUN (Session Traversal Utilities for NAT) requests bypass your VPN tunnel and reach out directly to the internet. This exposes your true ISP-assigned IP address, compromising your anonymity and privacy.

Why Should You Check for WebRTC Leaks?

How to Fix WebRTC Leaks

Fixing a WebRTC leak often involves disabling WebRTC in your browser or using extensions that block these requests. Here is how you can mitigate the risk on popular browsers:

• 1
  Use a VPN with Leak ProtectionChoose a high-quality VPN provider that offers built-in WebRTC leak protection. Ensure this feature is enabled in your VPN app settings.
• 2
  Browser ExtensionsInstall reputable privacy extensions like uBlock Origin or specialized WebRTC blocking extensions (e.g., "WebRTC Control") to prevent your browser from leaking local IP addresses.
• 3
  Manual ConfigurationAdvanced users can manually disable WebRTC in browser settings (e.g., `media.peerconnection.enabled` set to `false` in Firefox's `about:config`). Note that this may break some web apps like Google Meet.
