Is .ch safe? The state of .ch domain security — Switzerland
.ch is safer than the internet average. Across 1,959,486 graded .ch domains, 48.4% score an F — cleaner than the 78.3% global average — better company than most of the web. 7.4% earn a B or better. Most .ch 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 .ch zone — covering Switzerland — 34.6% of 1,428,565 graded domains earn an F, well below the 73.8% internet-wide average. DMARC enforcement here stands at 33.2% — above the 11.8% census-wide rate.
Note: .ch is used as a proxy for Switzerland based on the domain's TLD, not where the company is registered.
How do .ch domains score?
Aggregate grade distribution across all graded .ch domains — we never publish an individual business's grade. As of 2026-08-16.

| A | 8,436 | 0.4% |

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

Frequently asked questions
Is .ch safe?
On average, .ch is safer than the internet average: 48.4% of its 1,959,486 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 .ch domains?
51.6% of .ch domains score above an F and 7.4% 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 .ch 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 .ch too.
What does "grade F" mean for a .ch 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.
