HTTPS & TLS

100/100A⁺

HTTPS certificateDigiCert Inc10/10
HTTPS with a valid certificate from DigiCert Inc.
Certificate expiry1364/4
The certificate is valid for another 136 days.
TLS versionTLS 1.34/4
Negotiates TLS 1.3, the current protocol: faster handshakes, forward secrecy always.
Old protocols3/3
Refuses the retired TLS 1.0 and 1.1.
Key strengthRSA 20482/2
A strong key: RSA 2048.
HTTP → HTTPS3083/3
http:// redirects straight to https://.
HSTS2 years · preload4/4
HSTS tells browsers to use HTTPS only, for 2 years.
HTTP/2 and HTTP/3HTTP/32/2
HTTP/2 and HTTP/3.

DNS

71/100C

Name servers answer4/44/5
Every name server answers, but they hold different versions of the zone (SOA serials differ).
DNSSEC0/3
Not signed with DNSSEC: a forged DNS answer for the domain cannot be told from the real one.
Name servers44/4
4 name servers for the domain.
CAA recordsdigicert.com2/2
CAA records name the authorities allowed to issue its certificates.

Email

79/100B

MTA-STS0/2
No MTA-STS: mail to the domain can be read in transit by stripping its encryption.
TLS reporting0/0.5
No TLS reporting: failed encrypted deliveries go unnoticed.
SPFredirect4/5
SPF follows another domain's policy (redirect=).
DMARCreject7/7
DMARC tells receivers to reject mail that fakes the domain (p=reject).
DKIMgoogle2/2
A DKIM key is published (selector google), so its mail can be signed.

Web & network

72/100C

Permissions-Policy0/0.5
No Permissions-Policy: embedded content may ask for camera, microphone or location.
IPv60/4
www.pinterest.com has no IPv6 address: IPv6-only networks reach it only through translation.
Content Security Policy3/3
A Content Security Policy limits which scripts the pages run.
X-Content-Type-Options2/2
X-Content-Type-Options: nosniff stops browsers guessing file types.
Framing2/2
Other sites cannot frame its pages (clickjacking protection).
Referrer-Policyorigin0.5/0.5
Referrer-Policy limits what other sites learn about where visitors came from.
RPKIvalid4/4
The route to the website is RPKI-valid: networks can reject hijacked announcements of it.

Dependencies

One company for everything5/5
The website, DNS and email do not all hang on one company.

DNS · 20%

At least two name servers that all answer and agree, DNSSEC, CAA records, and a registration that is not about to expire.

Email · 20%

SPF, a DMARC policy that rejects forgeries (none means at most B), MTA-STS and TLS reporting for domains that take mail, DKIM at common selectors.

Web & network · 20%

Content Security Policy, nosniff, framing protection, Referrer- and Permissions-Policy, IPv6, and an RPKI-valid route (invalid means at most C).

Dependencies · 15%
