HTTPS & TLS
75/100B- TLS versionTLS 1.22/4
Negotiates TLS 1.2 at best; TLS 1.3 is faster and drops old ciphers.
- HSTS0/4
No HSTS: a visitor's first request can be downgraded to plain HTTP.
- HTTP/2 and HTTP/3HTTP/1.10/2
Only HTTP/1.1: no multiplexing, slower pages.
- HTTPS certificateDigiCert Inc10/10
HTTPS with a valid certificate from DigiCert Inc.
- Certificate expiry864/4
The certificate is valid for another 86 days.
- Old protocols3/3
Refuses the retired TLS 1.0 and 1.1.
- Key strengthRSA 20482/2
A strong key: RSA 2048.
- HTTP → HTTPS3013/3
http:// redirects straight to https://.
DNS
79/100B- 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.
- Name servers answer4/45/5
Every name server answers for the domain, with the same version of the zone.
- CAA recordsamazontrust.com, symantec.com, awstrust.com, amazon.com, letsencrypt.org, amazonaws.com, comodo.com, globalsign.com, digicert.com2/2
CAA records name the authorities allowed to issue its certificates.
- 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.
- SPF-all5/5
SPF lists the servers allowed to send its mail and rejects the rest (-all).
- DKIMs12/2
A DKIM key is published (selector s1), so its mail can be signed.
Web & network
47/100F- Content Security Policypartial1.5/3
A Content Security Policy is sent, but it does not limit scripts.
- Framing0/2
Any site can show its pages in a frame, which enables clickjacking.
- 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.globo.com has no IPv6 address: IPv6-only networks reach it only through translation.
- X-Content-Type-Options2/2
X-Content-Type-Options: nosniff stops browsers guessing file types.
- RPKIvalid4/4
The route to the website is RPKI-valid: networks can reject hijacked announcements of it.
Dependencies
80/100B- DNS providersSelf-hosted3/5
All DNS is with one provider (Self-hosted): an outage there takes the domain offline, as Dyn's did in 2016.
- One company for everything5/5
The website, DNS and email do not all hang on one company.

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.
