HTTPS & TLS

94/100A

HSTS7 days2/4
HSTS is on, but only for 7 days.
HTTPS certificateGoogle Trust Services10/10
HTTPS with a valid certificate from Google Trust Services.
Certificate expiry574/4
The certificate is valid for another 57 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

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~all4/5
SPF lists the servers allowed to send its mail and marks the rest as suspicious (~all).
DKIMgoogle2/2
A DKIM key is published (selector google), so its mail can be signed.

Web & network

44/100F

Content Security Policy0/3
No Content Security Policy: an injected script runs with the page's full rights.
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.
RPKIunknown1/4
The route to the website is not covered by RPKI, so a hijack of it cannot be told apart.
X-Content-Type-Options2/2
X-Content-Type-Options: nosniff stops browsers guessing file types.
IPv64/4
www.crunchyroll.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.

Website: Cloudflare
DNS: Cloudflare

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.
