HTTPS & TLS

88/100A

HSTS0/4
No HSTS: a visitor's first request can be downgraded to plain HTTP.
HTTPS certificateGoogle Trust Services10/10
HTTPS with a valid certificate from Google Trust Services.
Certificate expiry404/4
The certificate is valid for another 40 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 strengthECDSA P-2562/2
A strong key: ECDSA P-256.
HTTP → HTTPS3013/3
http:// redirects straight to https://.
HTTP/2 and HTTP/3HTTP/32/2
HTTP/2 and HTTP/3.

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.

Email

48/100F

SPF31/5
SPF needs 3 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.
DMARCquarantine5/7
DMARC sends mail that fakes the domain to spam (p=quarantine).
DKIMgoogle2/2
A DKIM key is published (selector google), so its mail can be signed.

Web & network

63/100D

RPKIunknown1/4
The route to the website is not covered by RPKI, so a hijack of it cannot be told apart.
Security headers
The website answered 403 to the check (bot protection, most likely), so its headers are not graded.
IPv64/4
midjourney.com is reachable over IPv6 as well as IPv4.

Dependencies

DNS providersCloudflare3/5
All DNS is with one provider (Cloudflare): an outage there takes the domain offline, as Dyn's did in 2016.
One company for everythingCloudflare: website, DNS3/5
Cloudflare runs both the website and the DNS: one outage there takes both down.

Who runs it

Website: Cloudflare
DNS: Cloudflare
Email: Google Workspace

What is graded

HTTPS & TLS · 25%

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.

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%

DNS from more than one provider, and the website, DNS and email not all with one company.
