Is .ooo safe? The state of .ooo domain security
.ooo is riskier than the internet average. Across 21,090 graded .ooo domains, 89.6% score an F — worse than the 78.3% global average — heavier on exposed domains than the web as a whole. 0.8% earn a B or better. Most .ooo 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 12,384 graded .ooo domains, 80.3% earn an F — well above the 73.8% internet-wide average. DMARC enforcement here stands at 6.4% — below the 11.8% census-wide rate.

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

Frequently asked questions
Is .ooo safe?
On average, .ooo is riskier than the internet average: 89.6% of its 21,090 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 .ooo domains?
10.4% of .ooo domains score above an F and 0.8% 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 .ooo 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 .ooo too.
What does "grade F" mean for a .ooo 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.
