noteCertificate Transparency did not complete (HTTP 429). 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.
note3 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.
asset: https://gamessumo.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://gamessumo.com/
The browser will also send this cookie over plain http://, where it can be captured.
What to do
Add `Secure` to the cookie.
asset: https://gamessumo.com/
Receivers are asked to report spoofing but not to block it. This is the right first step, and the wrong place to stop.
What to do
Once reports look clean, move to p=quarantine, then p=reject.
asset: gamessumo.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://gamessumo.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://gamessumo.com/
Exact versions in response headers let anyone match the server against a CVE feed without touching it.
What to do
Strip version tokens (`ServerTokens Prod`, `server_tokens off`, remove X-Powered-By).
asset: https://gamessumo.com/
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://gamessumo.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: gamessumo.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: gamessumo.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"`.
