Security Baseline Check

A free email and website security check for your domain. Enter it and we check eight things against a published baseline: SPF, DMARC and DKIM for your email, and a valid HTTPS certificate, the redirect from http://, HSTS, insecure content and cookies for your homepage. If your domain passes, you can prove you control it and show a badge with the date of the last check. We re-check every week.
