IP & WebRTC Leak Shield — Proxy Universe

Test your IP, WebRTC & DNS leaks in one click and block WebRTC from leaking your real IP behind a VPN or proxy.

Is your VPN or proxy actually hiding you? Most people never find out — until their real IP leaks through WebRTC. Leak Shield fixes both halves of the problem: it TESTS every leak vector in one click, and it BLOCKS the WebRTC leak that other checkers only warn you about. ★ WHAT IT DOES • Instant leak test — public IP, WebRTC, IPv6 and anonymity in one view • One glance verdict: Protected or Exposed • Real WebRTC protection — flip one switch to stop WebRTC from revealing your real IP (most extensions only detect the leak, we fix it) • Full report page — anonymity score /100, ISP, location, VPN/Proxy/Tor/Datacenter detection and your browser fingerprint (timezone, language, platform, screen) • Balanced & Strict protection modes for power users ★ WHY LEAK SHIELD • 100% private — every check runs locally in your browser. We never collect, store or transmit your data. • Minimal permissions — only "privacy" and "storage". No access to your browsing history, no host permissions, no tracking. • Clean, premium dark-blue interface that gets out of your way. • Fully localized: English and Русский. ★ WHO IT'S FOR Anyone using a VPN or proxy, remote workers, journalists, researchers, developers, and privacy-conscious users who want proof — not promises — that their real IP stays hidden. Turn on protection, run a check, and see the difference instantly. Made by Proxy Universe — fast, private proxies for everyone. https://proxyuniverse.org
