Is .rest safe? The state of .rest domain security
.rest is riskier than the internet average. Across 71,236 graded .rest domains, 80.3% score an F — worse than the 73.8% global average — heavier on exposed domains than the web as a whole. 0.4% earn a B or better. Most .rest domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-07-29.
How do .rest domains score?
Aggregate grade distribution across all graded .rest domains — we never publish an individual business's grade. As of 2026-07-29.
| Grade | Domains | Share |
|---|---|---|
| A+ | 2 | 0% |
| A | 11 | 0% |
| B | 247 | 0.3% |
| C | 3,472 | 4.9% |
| D | 10,308 | 14.5% |
| F | 57,196 | 80.3% |
Does .rest 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 .rest doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .rest domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .rest safe?
On average, .rest is riskier than the internet average: 80.3% of its 71,236 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 .rest domains?
19.7% of .rest domains score above an F and 0.4% 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 .rest 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 .rest too.
What does "grade F" mean for a .rest 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.
