HTTPS & TLS

100/100A⁺

HTTPS certificateSectigo Limited10/10
HTTPS with a valid certificate from Sectigo Limited.
Certificate expiry714/4
The certificate is valid for another 71 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 → HTTPS3023/3
http:// redirects straight to https://.
HSTS1 year · preload4/4
HSTS tells browsers to use HTTPS only, for 1 year.
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 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.

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.
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).

Web & network

84/100B

Content Security Policypartial1.5/3
A Content Security Policy is sent, but it does not limit scripts.
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.
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).
IPv64/4
www.intel.com is reachable over IPv6 as well as IPv4.
RPKIvalid4/4
The route to the website is RPKI-valid: networks can reject hijacked announcements of it.

Dependencies

80/100B

DNS providersSelf-hosted3/5
All DNS is with one provider (Self-hosted): an outage there takes the domain offline, as Dyn's did in 2016.
One company for everything5/5
The website, DNS and email do not all hang on one company.

Who runs it

Website: Akamai
DNS: Self-hosted
Email: Self-hosted

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.
