Prevents WebRTC IP leaks. Protects your real IP address even when using a VPN. WebRTC Leak Protection by DataSec helps stop websites from showing your real IP address even if you have VPN turned on through WebRTC. With just one click, it makes your browser's WebRTC settings more secure, checks if your public IP is visible, and shows a flashing warning if a leak is found. It's light, private, and easy to use. Key features include: a toggle for WebRTC protection, a one-click test that checks your public IP, and a red, flashing warning icon when a leak is detected. It supports English and Russian. It doesn't collect any data and runs directly on your device. How it works: the extension sets Chrome's WebRTC settings to block non-proxied UDP traffic, which is often the cause of IP leaks. The built-in test checks your public IP and tells you if it's protected. Privacy: no tracking, no analytics, and no user data is collected. It only makes network requests to check your public IP during the test.
WebRTC Leak Test: Protect your IP from WebRTC Leaks
Protects your privacy by preventing WebRTC IP leaks and forcing traffic through your VPN/Proxy. WebRTC (Web Real-Time Communication)—can bypass security layers and "leak" your true public and local IP addresses to websites. This vulnerability, known as a WebRTC leak, allows advertisers, trackers, and malicious actors to pinpoint your physical location and identify your device through fingerprinting. Reclaim Your Anonymity with the Advanced WebRTC Shield & Leak Checker. WebRTC Leak Shield is a high-performance security tool designed to plug this hole instantly. Built on the modern Manifest V3 framework, it provides a persistent, hardened defense against unauthorized data exposure. Why You Need WebRTC Leak Shield: Most browsers prioritize speed for video calls and P2P sharing, often at the expense of your privacy. Our extension muzzles this behavior by forcing the browser to follow a strict "Proxy Only" policy. This ensures that your network identity is never revealed outside of your authorized VPN or Proxy connection. Active WebRTC Shield: Leverages the chrome.privacy API to disable the browser’s ability to "shout" your IP. It effectively creates a firewall between your browser’s communication engine and your real network hardware. Precision Leak Checker: Our built-in diagnostic engine uses RTCPeerConnection and STUN simulations to perform a "stress test" on your connection. With one click, you can see exactly what a website sees—confirming your safety or flagging a risk. Anti-Fingerprinting Technology: By masking mDNS and local network addresses (10.x.x.x, 192.168.x.x), we prevent trackers from using your internal network ID to recognize your device across different sessions. Seamless Persistence: Unlike basic tools, our extension saves your "Hardened" state using chrome.storage.local. Your protection stays "ON" even after a browser restart or a tab refresh.
