Is .run safe? The state of .run domain security
.run is about average for the internet. Across 47,909 graded .run domains, 76.4% score an F — roughly in line with the 73.8% global average. 2% earn a B or better. Most .run 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 .run domains score?
Aggregate grade distribution across all graded .run domains — we never publish an individual business's grade. As of 2026-07-29.
| Grade | Domains | Share |
|---|---|---|
| A+ | 15 | 0% |
| A | 51 | 0.1% |
| B | 871 | 1.8% |
| C | 3,664 | 7.6% |
| D | 6,704 | 14% |
| F | 36,604 | 76.4% |
Does .run 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 .run doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .run domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .run safe?
On average, .run is about average for the internet: 76.4% of its 47,909 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 .run domains?
23.6% of .run domains score above an F and 2% 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 .run 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 .run too.
What does "grade F" mean for a .run 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.
