Browser Leak Test: Privacy Audit

Are you truly anonymous? Our browser leak test scans 20+ privacy vectors to see if your VPN or browser is leaking your real identity through WebRTC, DNS, or hardware fingerprinting.

AI Overview

A Browser Leak Test scans for vulnerabilities that expose your real location and hardware details. It checks for WebRTC leaks (revealing your real IP behind a VPN), DNS leaks (showing your browsing to your ISP), and Fingerprinting (identifying your device via GPU and font data).

What is a Browser Leak?

A browser leak occurs when your web browser shares more information than you intend. Even with a VPN, technologies like WebRTC and DNS can bypass your secure tunnel and show your real home IP address to any website you visit.

Quick Fix: If you detect a WebRTC leak, use Brave Browser or a privacy extension like "uBlock Origin" to block stun server requests.

Types of Leaks We Detect

  • WebRTC Leaks: These reveal your Local and Public IP addresses. It is the number one reason VPN users get tracked.
  • DNS Leaks: If your DNS queries go to your ISP instead of your VPN, every site you visit is recorded by your provider.
  • Hardware Fingerprinting: Websites read your GPU model, screen resolution, and battery level to create a unique ID that follows you without cookies.
  • Software Leaks: Your browser reveals its version, language, and installed fonts, narrowing down your identity.

How to Secure Your Browser

On ZKB Tracking, we recommend a multi-layered approach to privacy. Use a Privacy-First Browser like Firefox or Brave. Always enable HTTPS-Only mode and disable WebRTC in your advanced settings. Combine these with a reputable VPN to mask your network footprint.

Frequently Asked Questions

Does Incognito mode stop leaks?
No. Incognito mode only clears your history locally. It does not stop WebRTC or Canvas fingerprinting from identifying you.

What is a high privacy score?
On our scale, a lower score is better. A score under 20 means you are well-protected from tracking.

Why does my real IP show up?
If you are using a VPN and see your real IP, your browser has a WebRTC leak. You must disable WebRTC in your browser settings.
