WebRTC is used by web browsers for voice and video chat applications like Skype for Web, Discord, and Google Hangouts. The free and open-source project enables users to set up peer-to-peer connections without the need for any extra plugins or applications, allowing for efficient real-time communication (the ‘RTC’ in WebRTC). Most modern web browsers now support and enable WebRTC by default, including desktop browsers like Chrome, Firefox, Safari, and Edge, as well as mobile browsers on Android and iOS.
The problem is that WebRTC compromises the security provided by VPNs, or virtual private networks. When a user connects to a VPN server, all of the internet traffic from their device should go through an encrypted tunnel to the VPN server. Among other benefits, this prevents websites and apps from determining the user’s real IP address, which is masked by that of the VPN server. An IP address is a string of numbers and decimals unique to every internet-connected device that can be used to determine location.
WebRTC supports browsers for PCs - Microsoft Edge, Google Chrome, Firefox, and Opera; for Android – Google Chrome 28, Firefox 24, Opera Mobile 12. Safari is listed as being in development. The facilities of WebRTC would be attractive, if it wasn’t for one small problem.
According to January 2015 TorrentFreak blog’s news, browsers supporting WebRTC suffer from a serious security flaw that compromises the security of VPN-tunnels, by allowing a true IP address of the user to be read. But that is not the only problem; it gets worse. Unfortunately, Internet freedom is not supported by all countries and there are governments which follow a policy of total censorship. In addition, hacker attacks, computer fraudulence and geo-restrictions are a problem.
So to solve this problem you need a high-quality VPN for WebRTC. Also, many people are afraid of some WebRTC VPN vulnerabilities, but there are some extra qualitative VPNs for WebRTC that have some functions which can to help in the situation.

How to stop WebRTC leaks on iOS
You can only disable WebRTC in mobile Safari on iOS 11 or earlier. The setting to disable it was removed in iOS 12. For later versions of iOS (12+), you can use ExpressVPN’s or NordVPN’s iOS app to mask your real IP address and prevent WebRTC leaks.
Disabling WebRTC on the Safari browser in iOS 11 or earlier is fairly similar to the desktop version:
- Open the Settings app on your iPhone or iPad
- Scroll down and tap on Safari > Advanced > Experimental Features
- Tap the switch next to Remove Legacy WebRTC API so it turns green
How to stop WebRTC leaks in Safari
Safari blocks sites from accessing your camera and microphone by default, so we’re really only concerned about the less severe type of WebRTC leak here. You can turn WebRTC off in the developer settings:
- Open Safari and go to Safari > Preferences…
- Go to the Advanced tab and check the box at the bottom that says Show Develop menu in menu bar
- Close the preferences menu and go to Develop > Experimental Features
- Check the option for Remove Legacy WebRTC API
How to stop WebRTC leaks in Microsoft Edge
Microsoft Edge now supports both WebRTC plus its own proprietary version, dubbed ORTC. Unfortunately, Edge does not allow you to disable either. You merely get the option to hide your local IP address over WebRTC connections, but not your public IP address.
If you’re an Edge user and you want to prevent WebRTC leaks, ExpressVPN and NordVPN will both get the job done. Websites will only see your VPN server’s public IP address and not your own when connected through either of their respective apps.
How to stop WebRTC leaks on Android
In the latest version of Chrome for Android (tested with 8.1.0 Oreo), it is not currently possible to completely disable WebRTC. Many other tutorials on this subject instruct users to disable WebRTC Stun origin header in the flag menu, but in our experience this does not work. Even if we disable every WebRTC-related setting, our real IP address leaks.
Notably, ExpressVPN and NordVPN do prevent this leak when we connect through their Android apps. Websites can still see an IP address, but it’s the VPN server’s IP address and not our real IP address.
We will update this section of the tutorial if we find a way to disable WebRTC in Android 8 Oreo or, when it is released, Android 9 Pie.
How to stop WebRTC leaks in Firefox
In Firefox, you can disable WebRTC in the browser settings:
- In the URL bar, enter:
- Run a search for:
- Double-click the entry to change it to False
Note that changes you make to the settings may not carry across updates, so you might need to re-adjust this setting again if your browser updates.
For those who use WebRTC for real-time communication over peer-to-peer connections on the browsers will be very useful to subscribe to one of the best VPNs for WebRTC. This is due to the fact that browsers supporting WebRTC suffer from a serious security flaw that compromises your true IP address.
In order to find the best WebRTC VPN you need to look through all the qualities the VPN for WebRTC should have. The best VPN for WebRTC should have multiple server locations, strong encryption protocols, a trial version and money-back guarantee. Moreover, the best WebRTC VPN should support Linux and Android platforms. The VPNs mentioned above will not let you down.
