Is .kr safe? The state of .kr domain security — South Korea
.kr is riskier than the internet average. Across 675,718 graded .kr domains, 91.8% score an F — worse than the 78.3% global average — heavier on exposed domains than the web as a whole. 0.3% earn a B or better. Most .kr domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-08-16.
In the .kr zone — covering South Korea — 88.2% of 415,206 graded domains earn an F, well above the 73.8% internet-wide average. DMARC enforcement here stands at 1.8% — below the 11.8% census-wide rate.
Note: .kr is used as a proxy for South Korea based on the domain's TLD, not where the company is registered.
How do .kr domains score?
Aggregate grade distribution across all graded .kr domains — we never publish an individual business's grade. As of 2026-08-16.
| Grade | Domains | Share |
|---|---|---|
| A+ | 28 | 0% |
| A | 139 | 0% |
| B | 1,724 | 0.3% |
| C | 9,563 | 1.4% |
| D | 44,204 | 6.5% |
| F | 620,060 | 91.8% |
Does .kr 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 .kr doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .kr domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .kr safe?
On average, .kr is riskier than the internet average: 91.8% of its 675,718 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 .kr domains?
8.2% of .kr domains score above an F and 0.3% 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 .kr 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 .kr too.
What does "grade F" mean for a .kr 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.
