Is .engineering safe? The state of .engineering domain security
.engineering is about average for the internet. Across 9,568 graded .engineering domains, 72.2% score an F — roughly in line with the 73.8% global average. 2.8% earn a B or better. Most .engineering 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 .engineering domains score?
Aggregate grade distribution across all graded .engineering domains — we never publish an individual business's grade. As of 2026-07-29.
| Grade | Domains | Share |
|---|---|---|
| A+ | 10 | 0.1% |
| A | 24 | 0.3% |
| B | 237 | 2.5% |
| C | 794 | 8.3% |
| D | 1,592 | 16.6% |
| F | 6,911 | 72.2% |
Does .engineering 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 .engineering doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .engineering domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .engineering safe?
On average, .engineering is about average for the internet: 72.2% of its 9,568 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 .engineering domains?
27.8% of .engineering domains score above an F and 2.8% 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 .engineering 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 .engineering too.
What does "grade F" mean for a .engineering 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.
