Is .fun safe? The state of .fun domain security
.fun is riskier than the internet average. Across 290,095 graded .fun domains, 89.2% score an F — worse than the 73.8% global average — heavier on exposed domains than the web as a whole. 0.5% earn a B or better. Most .fun domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-07-29.

Does .fun 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 .fun doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .fun domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .fun safe?
On average, .fun is riskier than the internet average: 89.2% of its 290,095 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 .fun domains?
10.8% of .fun 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 .fun 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 .fun too.
What does "grade F" mean for a .fun 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.
