Free website security check

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.

What this website security check covers

SSL certificate

See the certificate issuer and expiry date for the public HTTPS endpoint.

Security headers

Review common browser protections such as HSTS, Content Security Policy, and frame controls.

Public DNS records

Inspect the domain's published web and mail records, including A and MX records.

Email protection

Check whether SPF and DMARC TXT records are published for the exact domain entered.

How to use the results

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.
