DNS
43/100F- Name servers answer7/82/5
7 of 8 name servers answer for the domain; the others leave resolvers waiting.
- DNSSEC0/3
Not signed with DNSSEC: a forged DNS answer for the domain cannot be told from the real one.
- CAA records0/2
No CAA records: any certificate authority may issue certificates for the domain.
- Name servers84/4
8 name servers for the domain.
- DMARCnone2/7
DMARC only watches (p=none): mail that fakes the domain is still delivered.
- 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.
- DKIM
No DKIM key at the common selectors; it may use one that cannot be guessed.
- SPF~all4/5
SPF lists the servers allowed to send its mail and marks the rest as suspicious (~all).
Web & network
38/100F- Content Security Policy0/3
No Content Security Policy: an injected script runs with the page's full rights.
- X-Content-Type-Options0/2
No X-Content-Type-Options: browsers may run an upload as a script.
- Referrer-Policy0/0.5
No Referrer-Policy of its own (browsers' default applies).
- Permissions-Policy0/0.5
No Permissions-Policy: embedded content may ask for camera, microphone or location.
- IPv60/4
www.samsung.com has no IPv6 address: IPv6-only networks reach it only through translation.
- Framing2/2
Other sites cannot frame its pages (clickjacking protection).
- RPKIvalid4/4
The route to the website is RPKI-valid: networks can reject hijacked announcements of it.

What is graded
A valid certificate (an invalid one means F), its expiry against its lifetime, TLS 1.3, no TLS 1.0/1.1 (else at most B), http:// sent straight to https://, HSTS, HTTP/2.
At least two name servers that all answer and agree, DNSSEC, CAA records, and a registration that is not about to expire.
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.
Content Security Policy, nosniff, framing protection, Referrer- and Permissions-Policy, IPv6, and an RPKI-valid route (invalid means at most C).
DNS from more than one provider, and the website, DNS and email not all with one company.
