HTTPS & TLS

88/100A
  • HSTS0/4

    No HSTS: a visitor's first request can be downgraded to plain HTTP.

  • HTTPS certificateMicrosoft Corporation10/10

    HTTPS with a valid certificate from Microsoft Corporation.

  • Certificate expiry1344/4

    The certificate is valid for another 134 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 strengthRSA 20482/2

    A strong key: RSA 2048.

  • HTTP → HTTPS3073/3

    http:// redirects straight to https://.

  • HTTP/2 and HTTP/3HTTP/22/2

    HTTP/2.

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 recordsletsencrypt.org, awstrust.com, pki.goog, microsoft.com, digicert.com2/2

    CAA records name the authorities allowed to issue its certificates.

Email

69/100C
  • 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
  • IPv60/4

    minecraft.net has no IPv6 address: IPv6-only networks reach it only through translation.

  • Security headers

    The website did not answer the check, so its headers are not graded.

  • RPKIvalid4/4

    The route to the website is RPKI-valid: networks can reject hijacked announcements of it.

Dependencies

40/100F
  • DNS providersAzure DNS3/5

    All DNS is with one provider (Azure DNS): an outage there takes the domain offline, as Dyn's did in 2016.

  • One company for everythingMicrosoft Azure: website, DNS, email1/5

    Microsoft Azure runs the website, DNS and email: one outage there takes all three down.

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.
