- HTTPS certificateLet's Encrypt10/10
HTTPS with a valid certificate from Let's Encrypt.
- Certificate expiry774/4
The certificate is valid for another 77 days.

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 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.
- 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-all5/5
SPF lists the servers allowed to send its mail and rejects the rest (-all).
- DMARCquarantine5/7
DMARC sends mail that fakes the domain to spam (p=quarantine).
Web & network
50/100D- Content Security Policy0/3
No Content Security Policy: an injected script runs with the page's full rights.
- 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.ovhcloud.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.
- 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.
Dependencies
80/100B- One company for everythingOVHcloud: website, email3/5
OVHcloud runs both the website and the email: one outage there takes both down.
- DNS providersOVHcloud, anycast.me5/5
DNS is served by 2 providers: one can fail without taking the domain offline.

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.
