Is .forum safe? The state of .forum domain security
.forum is riskier than the internet average. Across 36,698 graded .forum domains, 83.7% 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 .forum 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 .forum 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 .forum doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .forum domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .forum safe?
On average, .forum is riskier than the internet average: 83.7% of its 36,698 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 .forum domains?
16.3% of .forum 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 .forum 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 .forum too.
What does "grade F" mean for a .forum 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.
