Tools
Privacy, DNS, network, and browser diagnostics. Use the full scan for a broad snapshot, or choose a focused tool when you need to validate a VPN, inspect a domain, check email authentication, or understand the browser signals visible to websites.
Network & leak tests
Check the addresses, resolvers, and browser network APIs that can expose your real connection. These tools are useful after joining a new Wi-Fi network, changing VPN servers, enabling split tunneling, or troubleshooting dual-stack IPv6 behavior.
Browser privacy
Inspect the identifiers a website can read from your browser and request metadata. Fingerprint, bot-detection, and header checks help explain why two browsers on the same network can still look different to anti-abuse systems.
DNS & domain intelligence
Resolve records, inspect registration data, check reverse DNS, and review certificates issued for a domain. Use this group when investigating infrastructure ownership, mail-server hostnames, or unexpected certificate transparency entries.
Email & domain security
Audit the public records that protect a sending domain and the passive security posture around a website. These checks cover SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, HTTPS, TLS, DNS, headers, CAA, DNSSEC, RPKI, registration lifecycle, and security.txt.
Reference data
Browse autonomous system profiles for major clouds, CDNs, ISPs, mobile carriers, VPN infrastructure, and technology networks. ASN context helps connect an IP address to the network that announces it.
