Is .support safe? The state of .support domain security
.support is about average for the internet. Across 37,066 graded .support domains, 79.5% score an F — roughly in line with the 78.3% global average. 2.2% earn a B or better. Most .support 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 34,425 graded .support domains, 79.7% earn an F — well above the 73.8% internet-wide average. DMARC enforcement here stands at 17.9% — above the 11.8% census-wide rate.

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

Frequently asked questions
Is .support safe?
On average, .support is about average for the internet: 79.5% of its 37,066 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 .support domains?
20.5% of .support domains score above an F and 2.2% 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 .support 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 .support too.
What does "grade F" mean for a .support 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.
