Is .doctor safe? The state of .doctor domain security

Across 7,499 graded .doctor domains, 86% score an F — worse than the 73.8% global average — heavier on exposed domains than the web as a whole. 0.9% earn a B or better. Most .doctor 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 .doctor 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 .doctor doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .doctor domain earns an A while the crowd around it sits at F.

Frequently asked questions

Is .doctor safe?

On average, .doctor is riskier than the internet average: 86% of its 7,499 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 .doctor domains?

14.0% of .doctor domains score above an F and 0.9% 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 .doctor 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 .doctor too.

What does "grade F" mean for a .doctor 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.
