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

Frequently asked questions
Is .museum safe?
On average, .museum is about average for the internet: 75.4% of its 1,103 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 .museum domains?
24.6% of .museum domains score above an F and 3.5% 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 .museum 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 .museum too.
What does "grade F" mean for a .museum 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.
