Analysis7

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.
noteNo registration data: RDAP has no record at this level.
note3 hosts were identified as CDN/edge infrastructure from ASN ownership rather than a cdncheck fingerprint.

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://iboys.de/
No X-Frame-Options or CSP frame-ancestors directive, so another site can load this page invisibly inside its own and trick users into clicking.
What to do
Send `X-Frame-Options: DENY` or `Content-Security-Policy: frame-ancestors ’none’`.
asset: https://iboys.de/
Browsers and the preload list expect at least six months; shorter values give little protection between visits.
What to do
Raise max-age to 31536000 (one year).
asset: https://iboys.de/
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`.
asset: https://iboys.de/
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: iboys.de
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: iboys.de
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"`.
