Check a public website's SSL certificate, HTTP security headers, and email domain protections in seconds.
Checks public information only. No login or active vulnerability testing. Results are a quick signal, not a complete security assessment.
See the certificate issuer and expiry date for the public HTTPS endpoint.
Review common browser protections such as HSTS, Content Security Policy, and frame controls.
Inspect the domain's published web and mail records, including A and MX records.
Check whether SPF and DMARC TXT records are published for the exact domain entered.
A missing header or record is a prompt for further review, not proof of a vulnerability. Some controls depend on your hosting setup and email configuration. The weighted score only covers the checks shown and can be lower for domains that do not send email. This tool checks publicly visible settings on the domain you enter; it does not test applications, scan ports, or validate every policy value. If your site redirects, enter its final domain and run the check again.
Share your website and the issues you want to investigate. We can discuss practical next steps for your hosting, website, or email setup.
