See your domain the way an attacker does.
One scan checks DNS and DNSSEC, email authentication, HTTPS and security headers, issued certificates and registered look-alike domains. Real lookups, live results, no account needed.

Get told when this domain gets worse.
Create a free account to monitor up to 25 domains. CrowID rescans them every day and alerts you when a check regresses, a certificate nears expiry or a new look-alike appears.
Forty-plus checks across five surfaces
Every finding comes with the evidence we saw and the exact change that fixes it.
Email you can't spoof
SPF syntax and lookup limits, DKIM on common selectors, DMARC policy and reporting, MTA-STS and TLS reporting.
A hardened front door
HTTPS reachability, redirects, HSTS strength, Content-Security-Policy, framing, MIME sniffing, referrer and permissions policies, version leaks, security.txt.
Names that look like yours
Typo, homoglyph and TLD variants of your domain, resolved live. Variants that accept mail are flagged first — they're how phishing starts.
