Is .fi safe? The state of .fi domain security — Finland
.fi is safer than the internet average. Across 482,608 graded .fi domains, 60.4% score an F — cleaner than the 78.3% global average — better company than most of the web. 2.2% earn a B or better. Most .fi 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 .fi zone — covering Finland — 51.8% of 372,032 graded domains earn an F, well below the 73.8% internet-wide average. DMARC enforcement here stands at 7.2% — below the 11.8% census-wide rate.
Note: .fi is used as a proxy for Finland based on the domain's TLD, not where the company is registered.
How do .fi domains score?
Aggregate grade distribution across all graded .fi domains — we never publish an individual business's grade. As of 2026-08-16.
| Grade | Domains | Share |
|---|---|---|
| A+ | 196 | 0% |
| A | 828 | 0.2% |
| B | 9,684 | 2% |
| C | 58,814 | 12.2% |

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

Frequently asked questions
Is .fi safe?
On average, .fi is safer than the internet average: 60.4% of its 482,608 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 .fi domains?
39.6% of .fi domains score above an F and 2.2% 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 .fi 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 .fi too.
What does "grade F" mean for a .fi 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.
