Issues found (12)

mediumDKIM key cannot be parsed (selector pm)

An unparseable key (selector pm) makes every signed message fail verification, as if DKIM were absent, and weakens DMARC.

lowNo OCSP stapling

The server does not staple the certificate revocation status. Every revocation check becomes an extra round trip to the CA, which slows the first visit and, if the CA endpoint is unreachable or the visitor's network blocks it, leaves the browser without a usable revocation status.

lowHSTS preload not enabled

Even with HSTS on, the very first visit is still exposed to SSL-stripping: the header only takes effect after one successful HTTPS visit. Browsers ship a preload list (Chromium's list is used by Chrome, Edge, Safari and Firefox) so the first connection goes straight to HTTPS.

lowWeak DKIM key: 1024-bit RSA (selector google)

At 1024 bits (selector google) the key is considered weak; 1024-bit keys can be broken cheaply, letting attackers sign mail that passes DKIM.

lowNo MTA-STS policy

Without it an attacker on the network path can force a downgrade to plaintext and read or modify mail such as contracts and payment details.

lowNo Content Security Policy

Without it, any injected script runs: session theft, fake payment forms, or card-skimming scripts on compromised pages. CSP limits the damage even when something else fails.

lowNo clickjacking protection

Without it, attackers overlay a transparent frame of your page and trick users into clicking real actions such as transfers or password changes (clickjacking).

lowNo CAA record

Without it any CA may issue certificates for your domain, enabling a lookalike site with a valid padlock.

lowDNSSEC not enabled

Without it, attackers can poison caches or forge answers and send visitors to a lookalike server that harvests credentials.

lowCookies without Secure/HttpOnly (localization)

Missing Secure lets cookies travel in plaintext; missing HttpOnly lets injected scripts steal sessions; missing SameSite enables CSRF. Affected: localization.

lowContent Security Policy is weak (no script-src/default-src; object-src not restricted)

The policy is too permissive (no script-src/default-src; object-src not restricted), so injected scripts still run while giving a false sense of security.

lowHSTS max-age is only 91 days

At 91 days the protection expires between visits, periodically reopening the window for SSL stripping.

What could not be fully checked

No TLS-RPT record
TLS-RPT sends you reports when other servers fail to deliver mail to you securely. Recommended alongside MTA-STS.
Wildcard DNS in use
Every subdomain name resolves. This hides typos and can make phishing subdomains look legitimate.
No Referrer-Policy 3 host(s)
Browsers default to strict-origin-when-cross-origin today; setting it explicitly is good hygiene.
No Permissions-Policy 3 host(s)
Permissions-Policy disables powerful browser features (camera, microphone, geolocation) you do not use.
No security.txt
security.txt (RFC 9116) tells security researchers how to report vulnerabilities to you instead of posting them publicly.
Website returned an error page — partly unassessed 6 host(s)
The page returned HTTP 404 (often a firewall challenge for automated clients), so most header and content checks could not run. HSTS was still assessed where the response is reliable, but this category is only partially evaluated and its score should be read as incomplete.
Website redirects to an external platform
Headers on third-party hosted pages are controlled by that platform and are not scored.
RSA key exchange still accepted 8 host(s)
Static RSA key exchange is kept for old clients. It lacks forward secrecy but is not scored when ECDHE is available.
