Is .fish safe? The state of .fish domain security
.fish is riskier than the internet average. Across 5,414 graded .fish domains, 79.8% score an F — worse than the 73.8% global average — heavier on exposed domains than the web as a whole. 2.1% earn a B or better. Most .fish 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 .fish domains score?
Aggregate grade distribution across all graded .fish domains — we never publish an individual business's grade. As of 2026-07-29.
| Grade | Domains | Share |
|---|---|---|
| A+ | 4 | 0.1% |
| A | 10 | 0.2% |
| B | 102 | 1.9% |
| C | 329 | 6.1% |
| D | 649 | 12% |
| F | 4,320 | 79.8% |
Does .fish 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 .fish doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .fish domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .fish safe?
On average, .fish is riskier than the internet average: 79.8% of its 5,414 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 .fish domains?
20.2% of .fish domains score above an F and 2.1% 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 .fish 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 .fish too.
What does "grade F" mean for a .fish 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.
