See exactly what the internet knows about you
IP intelligence, browser fingerprinting, DNS & WebRTC leak detection, and bot analysis - all in one real-time scan.
Check the public security posture of any domain
Domain Security brings HTTPS, certificate quality, HSTS, DNSSEC, CAA, RPKI, security headers, registration, CT logs, security.txt, and email authentication into one practical scanner.
7-phase privacy audit
A comprehensive scan delivered in real-time via WebSocket. PrivKit combines browser-side checks with network intelligence so you can see the identifiers, leak paths, and trust signals that websites and security systems receive during a normal visit.
Network & IP
Geolocation, ASN, reverse DNS, VPN / proxy / Tor / hosting detection, blacklist checks.
Browser Fingerprint
Canvas, WebGL, audio, fonts, WebGPU, CSS - over 20 signals to measure your uniqueness.
DNS Leak Test
Verify your DNS queries aren't leaking outside the VPN tunnel to your ISP.
WebRTC Leak Test
Detect STUN/TURN IP leaks that expose your real IP despite VPN use.
Bot Detection
10+ client-side checks for WebDriver, Selenium, Puppeteer, and headless browsers.
HTTP Headers
Inspect every request header your browser sends - user-agent, accept, encoding, and more.
Standalone tools
Run any check individually when you need a focused answer. Use IP Lookup before trusting a network, DNS and WebRTC tests when validating a VPN, domain tools when investigating infrastructure, and email security checks before sending from a production domain.
ASN List
Network intelligence for 200+ autonomous systems.
Built for privacy
Transparent, open-source, and designed with security researchers in mind. Results are streamed to your browser for immediate inspection, and the tools avoid cross-site tracking patterns that would undermine the privacy checks they perform.
Privacy Focused
No Facebook Pixel, no cross-site tracking cookies. We practice what we preach.
Data not stored
Scan results are streamed to your browser and never saved to our database.
Real-time results
WebSocket-powered scanning completes in seconds - no waiting for batch processing.
Featured privacy guides
Diagnostics are most useful when you understand the mechanism behind the result. These guides explain the most common privacy and security signals PrivKit tests, with practical steps for browser hardening, VPN validation, and domain authentication.
