What it does
DomSec HQ checks your domain's email authentication and web security in seconds - SPF, DKIM, DMARC, BIMI, MX, blacklist status, MTA-STS, TLSRPT, DNSSEC, SSL/TLS, and security headers. 5 checks are free with no signup; create a free account to unlock all 11 plus a downloadable PDF report.
