Check whether your IP appears on Spamhaus, SORBS and other reputation databases - and why a public DNS resolver gives a false all-clear.

Run a free VPN leak test to detect IP, DNS, and WebRTC leaks. Verify your VPN is hiding your real IP, not exposing your identity through hidden channels.

A sweeping new analysis published April 14, 2026 reveals Google Chrome provides virtually no effective protection against browser fingerprinting. Researchers identified over 30 fingerprinting vectors that silently collect device information without user consent during ordinary web browsing.

See how your browser can be uniquely identified. Inspect high-entropy fingerprint signals — Canvas/WebGL, fonts, language order, WebRTC — and learn how to reduce tracking risk and avoid fraud detection false positives.

Detailed analysis of ClickFix and CrashFix attack chains, with specific detection commands and defense configurations

Run a DNS leak test to check if your VPN exposes your DNS queries. Identify leak sources, compare resolvers, and apply step-by-step fixes to reclaim privacy.

Inspect HTTP headers your browser sends and server responses. Analyze CSP, HSTS, Referrer-Policy, and privacy signals for security and debugging.

Inspect your TLS handshake fingerprint. Understand how servers identify client stacks and detect anomalies.

Understand how TLS fingerprints are built, why they matter for access stability, and how to diagnose fingerprint mismatches in production environments.

Find out if WebRTC is exposing your real IP even when you're behind a VPN. This test checks ICE candidates to identify local and public IP leaks.
