Domain scan

Enter a domain. We run 28 public checks and you get a shareable link with the result.

Free, no signup. We check DNS fundamentals (NS, A, AAAA, SOA, CAA, DNSSEC, glue), email DNS (SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT, BIMI), TLS/SSL (cert, versions, ciphers, HSTS, OCSP), HTTP security headers and DNSBL reputation. Result lives on a private link, not indexed.
