Is .tel safe? The state of .tel domain security
.tel is riskier than the internet average. Across 31,006 graded .tel domains, 87.3% score an F — worse than the 73.8% global average — heavier on exposed domains than the web as a whole. 1.7% earn a B or better. Most .tel domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-07-29.

Aggregate grade distribution across all graded .tel domains — we never publish an individual business's grade. As of 2026-07-29.

|---|---|---|
| A+ | 10 | 0% |
| A | 66 | 0.2% |
| B | 463 | 1.5% |

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

Frequently asked questions
Is .tel safe?
On average, .tel is riskier than the internet average: 87.3% of its 31,006 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 .tel domains?
12.7% of .tel domains score above an F and 1.7% 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 .tel 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 .tel too.
What does "grade F" mean for a .tel 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.
