HTTPS & TLS
81/100B- 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.
- HTTPS certificateGlobalSign nv-sa10/10
HTTPS with a valid certificate from GlobalSign nv-sa.
- Certificate expiry504/4
The certificate is valid for another 50 days.
- Old protocols3/3
Refuses the retired TLS 1.0 and 1.1.
- Key strengthECDSA P-2562/2
A strong key: ECDSA P-256.
- HTTP → HTTPS3013/3
http:// redirects straight to https://.
- HTTP/2 and HTTP/3HTTP/22/2
HTTP/2.
DNS
64/100D- 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 servers24/4
2 name servers for the domain.
- Name servers answer2/25/5
Every name server answers for the domain, with the same version of the zone.
- SPF81/5
SPF needs 8 DNS lookups (at most 10 are allowed), so it fails at receivers.
Flatten includes you no longer use, or replace them with ip4:/ip6: ranges.
- 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.
- DMARCreject7/7
DMARC tells receivers to reject mail that fakes the domain (p=reject).
- DKIMs12/2
A DKIM key is published (selector s1), so its mail can be signed.
Web & network
25/100F- 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.
- 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
aliexpress.com has no IPv6 address: IPv6-only networks reach it only through translation.
- 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.
