Is .diy safe? The state of .diy domain security
.diy is riskier than the internet average. Across 6,792 graded .diy domains, 90.6% score an F — worse than the 73.8% global average — heavier on exposed domains than the web as a whole. 0.7% earn a B or better. Most .diy 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 .diy domains score?
Aggregate grade distribution across all graded .diy domains — we never publish an individual business's grade. As of 2026-07-29.
| Grade | Domains | Share |
|---|---|---|
| A+ | 2 | 0% |
| A | 5 | 0.1% |
| B | 39 | 0.6% |
| C | 204 | 3% |
| D | 386 | 5.7% |
| F | 6,156 | 90.6% |
Does .diy 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 .diy doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .diy domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .diy safe?
On average, .diy is riskier than the internet average: 90.6% of its 6,792 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 .diy domains?
9.4% of .diy domains score above an F and 0.7% 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 .diy 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 .diy too.
What does "grade F" mean for a .diy 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.
