WebRTC (Web Real-Time Communication) is a technology that enables real-time voice and video communication in your web browser without the need for plugins. However, it also poses a threat to your online privacy by exposing your real IP address, even if you are using a VPN.

This is because WebRTC can bypass the VPN and leak your real IP, which can be used by websites and advertisers to track your online activity. In this blog post, we will explain what WebRTC leaks are and how you can check and prevent them from happening.

What is a WebRTC leak?

A WebRTC leak is a security vulnerability that exposes your real IP address, even when you are using a VPN. This happens when a website or an app uses the WebRTC API to access your device's network information, including your IP address.

How to check for WebRTC leaks?

There are several online tools available to check for WebRTC leaks. To use them, simply go to the website and run the test. Here are a few popular tools that you can use:

  1. AstroVPN - WebRTC Leaks
  2. BrowserLeaks

Protecting your online privacy from WebRTC leaks

  1. Disable WebRTC in your web browser

Most modern web browsers have the option to disable WebRTC. To do this, you will need to install a browser extension, such as the WebRTC Leak Prevent for Chrome or the Disable WebRTC for Firefox.

2. Use a VPN with WebRTC leak protection

A VPN can encrypt your internet traffic and protect your online privacy by hiding your real IP address. However, not all VPNs can prevent WebRTC leaks. To ensure that your VPN has WebRTC leak protection, look for a VPN provider that offers the WebRTC leak protection feature.

3. Use a firewall

A firewall can prevent WebRTC from accessing your network information by blocking the WebRTC API. To use a firewall to prevent WebRTC leaks, you will need to configure your firewall to block the WebRTC API.

WebRTC leaks can expose your real IP address, even when you are using a VPN. To protect your online privacy, it's important to check for WebRTC leaks and take measures to prevent them from happening. By disabling WebRTC in your web browser, using a VPN with WebRTC leak protection, or using a firewall, you can secure your online privacy and protect yourself from potential security threats.
