HTTPS with a valid certificate from Google Trust Services.
- Certificate expiry734/4
The certificate is valid for another 73 days.

DNS
86/100A- 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.
- DNSSECRSASHA2563/3
Signed with DNSSEC: resolvers can tell forged answers from real ones.
- 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-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).
- DKIMgoogle2/2
A DKIM key is published (selector google), so its mail can be signed.
Web & network
47/100F- Content Security Policypartial1.5/3
A Content Security Policy is sent, but it does not limit scripts.
- X-Content-Type-Options0/2
No X-Content-Type-Options: browsers may run an upload as a script.
- 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.
- IPv60/4
elevenlabs.io has no IPv6 address: IPv6-only networks reach it only through translation.
- Framing2/2
Other sites cannot frame its pages (clickjacking protection).
- RPKIvalid4/4
The route to the website is RPKI-valid: networks can reject hijacked announcements of it.
Dependencies
40/100F- DNS providersGoogle Cloud DNS3/5
All DNS is with one provider (Google Cloud DNS): an outage there takes the domain offline, as Dyn's did in 2016.
- One company for everythingGoogle Cloud: website, DNS, email1/5
Google Cloud runs the website, DNS and email: one outage there takes all three down.
Who runs it

- Google Cloud
- Google Workspace

What is graded
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.
At least two name servers that all answer and agree, DNSSEC, CAA records, and a registration that is not about to expire.
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.
Content Security Policy, nosniff, framing protection, Referrer- and Permissions-Policy, IPv6, and an RPKI-valid route (invalid means at most C).
DNS from more than one provider, and the website, DNS and email not all with one company.
