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.
note1 host was identified as CDN/edge infrastructure from ASN ownership rather than a cdncheck fingerprint.

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://friendludo.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.friendludo.com TXT "v=DMARC1; p=none; rua=mailto:dmarc@friendludo.com"`, review the reports, then move to p=quarantine and p=reject.
asset: friendludo.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://friendludo.com/
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://friendludo.com/
Nothing tells receiving mail servers which hosts may send as @friendludo.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: friendludo.com
3.7.201.227 (apiv2.friendludo.com) reports jquery 3.6.0, bootstrap 5.1.3. Publishing precise versions lets anyone match the host against a CVE feed without probing it, which is how targets get shortlisted for mass exploitation after a new advisory lands.
What to do
Suppress version tokens in server banners (for example `ServerTokens Prod` in Apache) and keep the packages current.
asset: 3.7.201.227
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://friendludo.com/
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://friendludo.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: friendludo.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"`.
