Is .fish safe? The state of .fish domain security
.fish is about average for the internet. Across 6,027 graded .fish domains, 80.2% score an F — roughly in line with the 78.3% global average. 1.9% 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 2026-08-16.
Of 5,414 graded .fish domains, 79.8% earn an F — well above the 73.8% internet-wide average. Only 0.3% reach an A or A+ — the highest protection tier in the census.
How do .fish domains score?
Aggregate grade distribution across all graded .fish domains — we never publish an individual business's grade. As of 2026-08-16.
| Grade | Domains | Share |
|---|---|---|
| A+ | 4 | 0.1% |
| A | 9 | 0.1% |
| B | 100 | 1.7% |
| C | 371 | 6.2% |
| D | 712 | 11.8% |
| F | 4,831 | 80.2% |
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 about average for the internet: 80.2% of its 6,027 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 .fish domains?
19.8% of .fish domains score above an F and 1.9% 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.
