Is .se safe? The state of .se domain security — Sweden
.se is safer than the internet average. Across 1,378,888 graded .se domains, 70.1% score an F — cleaner than the 78.3% global average — better company than most of the web. 3% earn a B or better. Most .se 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 .se zone — covering Sweden — 63.1% of 1,026,590 graded domains earn an F, well below the 73.8% internet-wide average. DMARC enforcement here stands at 8.5% — below the 11.8% census-wide rate.
Note: .se is used as a proxy for Sweden based on the domain's TLD, not where the company is registered.
How do .se domains score?
Aggregate grade distribution across all graded .se domains — we never publish an individual business's grade. As of 2026-08-16.
| Grade | Domains | Share |
|---|---|---|
| A+ | 899 | 0.1% |
| A | 3,246 | 0.2% |
| B | 36,610 | 2.7% |
| C | 118,205 | 8.6% |
| D | 252,739 | 18.3% |
| F | 967,189 | 70.1% |
Does .se 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 .se doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .se domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .se safe?
On average, .se is safer than the internet average: 70.1% of its 1,378,888 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 .se domains?
29.9% of .se domains score above an F and 3% 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 .se 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 .se too.
What does "grade F" mean for a .se 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.
