noteCertificate Transparency did not complete (HTTP 502). Results below are partial.
noteCertificate inspection is unavailable in this runtime.
noteNetwork ownership lookup is unavailable in this runtime; ASN and org are omitted.
noteCDN/WAF detection is unavailable in this runtime.

A visitor who types the address without https, or follows an old link, gets the unencrypted site. On public Wi-Fi that page can be read and rewritten in transit.
What to do
Redirect every http:// request to https:// with a 301, then add HSTS.
asset: https://gdmcyx.com/
SPF and DKIM alone do not protect the From: address a person sees. Without DMARC, a spoofed message can pass SPF for some other domain and still display yours.
What to do
Publish `_dmarc.gdmcyx.com TXT "v=DMARC1; p=none; rua=mailto:dmarc@gdmcyx.com"`, review the reports, then move to p=quarantine and p=reject.
asset: gdmcyx.com
Without HSTS the browser will still try http:// first on a fresh visit, which is the window an on-path attacker uses.
What to do
Send `Strict-Transport-Security: max-age=31536000; includeSubDomains` once you are sure everything works over HTTPS.
asset: https://gdmcyx.com/
CSP is the main defence that limits what an injected script can do. Without it, any XSS bug is fully exploitable.
What to do
Start with a report-only policy, tighten it against the reports, then enforce.
asset: https://gdmcyx.com/
Nothing tells receiving mail servers which hosts may send as @gdmcyx.com, so anyone can. Even a domain that sends no mail should say so, or it becomes a free spoofing target.
What to do
Publish `v=spf1 -all` to state that this domain sends no mail.
asset: gdmcyx.com
Without clientTransferProhibited, a compromised registrar account can move the domain to another registrar in days, with no second step.
What to do
Enable the transfer lock (and registrar lock, if offered) in the registrar control panel.
asset: gdmcyx.com
Lets browsers guess content types, which turns some upload and text endpoints into script injection points.
What to do
Send `X-Content-Type-Options: nosniff` on every response.
asset: https://gdmcyx.com/
Answers for this domain are not signed, so a resolver cannot tell a forged response from a real one.
What to do
Enable DNSSEC at your DNS host and publish the DS record at the registrar.
asset: gdmcyx.com
Any public certificate authority may issue certificates for this domain. CAA lets you name the ones allowed to.
What to do
Add a CAA record naming your CA, e.g. `0 issue "letsencrypt.org"`.
