Is .cx safe? The state of .cx domain security
.cx is about average for the internet. Across 14,578 graded .cx domains, 77.3% score an F — roughly in line with the 78.3% global average. 3.5% earn a B or better. Most .cx domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-08-16.
Of 11,203 graded .cx domains, 70.4% earn an F — below the 73.8% internet-wide average. Only 0.8% reach an A or A+ — the highest protection tier in the census.

Aggregate grade distribution across all graded .cx domains — we never publish an individual business's grade. As of 2026-08-16.

|---|---|---|
| A+ | 27 | 0.2% |
| A | 78 | 0.5% |

Does .cx make a domain secure?
No — and that's the most important thing to know. A domain's grade is decided by how it is configured (SPF, DMARC, HTTPS, DNS), not by its ending. Choosing .cx doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .cx domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .cx safe?
On average, .cx is about average for the internet: 77.3% of its 14,578 graded domains score an F as of 2026-08-16, against a 78.3% global average. Most domains on every ending are exposed — the ending shifts the odds, not your own domain's grade.
How secure are .cx domains?
22.7% of .cx domains score above an F and 3.5% earn a B or better. The rest fail the basic externally observable protections, most importantly enforced SPF and DMARC, so they can be impersonated in email.
Does choosing .cx make my domain secure?
No. A domain's grade comes from how it is configured — SPF, DMARC, HTTPS, DNS — not from its ending. A well-configured domain earns an A on any ending; an unconfigured one sits at F on .cx too.
What does "grade F" mean for a .cx domain?
It fails the basic protections we can observe from outside — above all, it has no enforced SPF and DMARC, so its email can be forged and its customers targeted with convincing fakes.
