FDD Shield
FDD Shield / Security

Check your website’s technical configuration.

An external check can identify publicly visible configuration issues. It does not inspect application internals, user permissions or all customer data.

Check your website

Non-invasive external check – public information only: encryption (HTTPS, TLS), security headers, cookies, page code, DNS and e-mail spoofing protection (SPF/DKIM/DMARC). Sensitive files and ports are not checked for free, nothing is attacked, no logins are tried, nothing is changed. It is not a security audit. Up to 6 checks per hour.

When you run a check we record the domain you enter, your IP address and the time, and keep them for 90 days to prevent abuse. See our privacy policy for details. You may only check websites that you own or are authorised to check.

01

Understanding results

A finding identifies something an administrator should investigate. A clean result does not prove that the website is secure.

02

Check only authorised websites

Use the service for websites you own or are authorised to assess. A broader assessment requires proof of domain control and an agreed scope.

03

How long does it take?

Duration depends on the target website’s response. The interface should show the actual task status rather than a guaranteed number of seconds.
