HTTPS with a valid certificate from Sectigo Limited.
Certificate expiry1724/4
The certificate is valid for another 172 days.

A strong key: ECDSA P-256.
HTTP → HTTPS3013/3
http:// redirects straight to https://.

HSTS tells browsers to use HTTPS only, for 182 days.
HTTP/2 and HTTP/3HTTP/22/2

DNS

86/100A

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.
DNSSECECDSAP256SHA2563/3
Signed with DNSSEC: resolvers can tell forged answers from real ones.

Email

83/100B

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).
DMARCreject7/7
DMARC tells receivers to reject mail that fakes the domain (p=reject).

Web & network

100/100A⁺

Security headers
The website answered 403 to the check (bot protection, most likely), so its headers are not graded.
IPv64/4
www.lufthansa.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

DNS is served by 2 providers: one can fail without taking the domain offline.
One company for everything5/5

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%
