Is .by safe? The state of .by domain security — Belarus
.by is about average for the internet. Across 136,141 graded .by domains, 75.4% score an F — roughly in line with the 78.3% global average. 0.7% earn a B or better. Most .by domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-08-16.
In the .by zone — covering Belarus — 46.9% of 99,582 graded domains earn an F, well below the 73.8% internet-wide average. DMARC enforcement here stands at 6% — below the 11.8% census-wide rate.
Note: .by is used as a proxy for Belarus based on the domain's TLD, not where the company is registered.

Aggregate grade distribution across all graded .by domains — we never publish an individual business's grade. As of 2026-08-16.

|---|---|---|
| A+ | 9 | 0% |
| A | 57 | 0% |
| B | 946 | 0.7% |

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

Frequently asked questions
Is .by safe?
On average, .by is about average for the internet: 75.4% of its 136,141 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 .by domains?
24.6% of .by domains score above an F and 0.7% 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 .by 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 .by too.
What does "grade F" mean for a .by 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.
