Analysis7

noteCertificate Transparency did not complete (HTTP 404). 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.
note2 hosts were identified as CDN/edge infrastructure from ASN ownership rather than a cdncheck fingerprint.

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.

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.

Full URLs — including any tokens or IDs in them — are sent to every third party the page links to.
What to do
Send `Referrer-Policy: strict-origin-when-cross-origin`.

Without HttpOnly, any injected script can read and exfiltrate this cookie.
What to do
Add `HttpOnly` unless client-side code genuinely needs to read it.
asset: https://groupdiy.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: groupdiy.com
Mail to this domain can be downgraded to plaintext by an on-path attacker, because senders have no way to know TLS is required.
What to do
Publish an MTA-STS policy (a TXT record plus a small HTTPS-hosted file).
asset: groupdiy.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"`.
