Is .vn safe? The state of .vn domain security — Vietnam
.vn is riskier than the internet average. Across 511,026 graded .vn domains, 86.1% score an F — worse than the 78.3% global average — heavier on exposed domains than the web as a whole. 0.7% earn a B or better. Most .vn 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 .vn zone — covering Vietnam — 80.7% of 330,947 graded domains earn an F, well above the 73.8% internet-wide average. DMARC enforcement here stands at 4.1% — below the 11.8% census-wide rate.
Note: .vn is used as a proxy for Vietnam based on the domain's TLD, not where the company is registered.
How do .vn domains score?
Aggregate grade distribution across all graded .vn domains — we never publish an individual business's grade. As of 2026-08-16.
| Grade | Domains | Share |
|---|---|---|
| A+ | 24 | 0% |
| A | 229 | 0% |
| B | 3,217 | 0.6% |
| C | 19,781 | 3.9% |

| F | 439,937 | 86.1% |
Does .vn 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 .vn doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .vn domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .vn safe?
On average, .vn is riskier than the internet average: 86.1% of its 511,026 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 .vn domains?
13.9% of .vn 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 .vn 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 .vn too.
What does "grade F" mean for a .vn 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.
