Is .wiki safe? The state of .wiki domain security
.wiki is riskier than the internet average. Across 112,647 graded .wiki domains, 94.4% score an F — worse than the 78.3% global average — heavier on exposed domains than the web as a whole. 0.5% earn a B or better. Most .wiki 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 100,249 graded .wiki domains, 87.6% earn an F — well above the 73.8% internet-wide average. DMARC enforcement here stands at 2.6% — below the 11.8% census-wide rate.
How do .wiki domains score?
Aggregate grade distribution across all graded .wiki domains — we never publish an individual business's grade. As of 2026-08-16.
| Grade | Domains | Share |
|---|---|---|
| A+ | 20 | 0% |
| A | 64 | 0.1% |
| B | 476 | 0.4% |
| C | 1,690 | 1.5% |
| D | 4,056 | 3.6% |
| F | 106,341 | 94.4% |
Does .wiki 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 .wiki doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .wiki domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .wiki safe?
On average, .wiki is riskier than the internet average: 94.4% of its 112,647 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 .wiki domains?
5.6% of .wiki domains score above an F and 0.5% 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 .wiki 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 .wiki too.
What does "grade F" mean for a .wiki 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.
