Is .sh safe? The state of .sh domain security
.sh is safer than the internet average. Across 30,549 graded .sh domains, 69.1% score an F — cleaner than the 78.3% global average — better company than most of the web. 4.3% earn a B or better. Most .sh 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 26,446 graded .sh domains, 59.4% earn an F — well below the 73.8% internet-wide average. DMARC enforcement here stands at 15.6% — above the 11.8% census-wide rate.
How do .sh domains score?
Aggregate grade distribution across all graded .sh domains — we never publish an individual business's grade. As of 2026-08-16.
| Grade | Domains | Share |
|---|---|---|
| A+ | 74 | 0.2% |
| A | 185 | 0.6% |
| B | 1,042 | 3.4% |
| C | 3,197 | 10.5% |
| D | 4,933 | 16.1% |
| F | 21,118 | 69.1% |
Does .sh 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 .sh doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .sh domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .sh safe?
On average, .sh is safer than the internet average: 69.1% of its 30,549 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 .sh domains?
30.9% of .sh domains score above an F and 4.3% 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 .sh 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 .sh too.
What does "grade F" mean for a .sh 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.
