Is .systems safe? The state of .systems domain security
.systems is about average for the internet. Across 37,943 graded .systems domains, 76.1% score an F — roughly in line with the 73.8% global average. 3.2% earn a B or better. Most .systems 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 .systems domains score?
Aggregate grade distribution across all graded .systems domains — we never publish an individual business's grade. As of 2026-07-29.
| Grade | Domains | Share |
|---|---|---|
| A+ | 58 | 0.2% |
| A | 177 | 0.5% |
| B | 985 | 2.6% |
| C | 2,967 | 7.8% |
| D | 4,886 | 12.9% |

Does .systems 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 .systems doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .systems domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .systems safe?
On average, .systems is about average for the internet: 76.1% of its 37,943 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 .systems domains?
23.9% of .systems domains score above an F and 3.2% 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 .systems 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 .systems too.
What does "grade F" mean for a .systems 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.
