Is .host safe? The state of .host domain security
.host is about average for the internet. Across 16,650 graded .host domains, 72.6% score an F — roughly in line with the 73.8% global average. 2.7% earn a B or better. Most .host domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-07-29.
How do .host domains score?
Aggregate grade distribution across all graded .host domains — we never publish an individual business's grade. As of 2026-07-29.
| Grade | Domains | Share |
|---|---|---|
| A+ | 14 | 0.1% |
| A | 63 | 0.4% |
| B | 372 | 2.2% |
| C | 1,366 | 8.2% |
| D | 2,741 | 16.5% |
| F | 12,094 | 72.6% |
Does .host 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 .host doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .host domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .host safe?
On average, .host is about average for the internet: 72.6% of its 16,650 graded domains score an F as of 2026-07-29, against a 73.8% global average. Most domains on every ending are exposed — the ending shifts the odds, not your own domain's grade.
How secure are .host domains?
27.4% of .host domains score above an F and 2.7% 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 .host 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 .host too.
What does "grade F" mean for a .host 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.
