Is .sg safe? The state of .sg domain security — Singapore
.sg is safer than the internet average. Across 140,296 graded .sg domains, 61.8% score an F — cleaner than the 78.3% global average — better company than most of the web. 3.7% earn a B or better. Most .sg 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 .sg zone — covering Singapore — 47.1% of 103,077 graded domains earn an F, well below the 73.8% internet-wide average. DMARC enforcement here stands at 17.3% — above the 11.8% census-wide rate.
Note: .sg is used as a proxy for Singapore based on the domain's TLD, not where the company is registered.
How do .sg domains score?
Aggregate grade distribution across all graded .sg domains — we never publish an individual business's grade. As of 2026-08-16.
| Grade | Domains | Share |
|---|---|---|
| A+ | 193 | 0.1% |
| A | 509 | 0.4% |
| B | 4,464 | 3.2% |
| C | 16,821 | 12% |
| D | 31,557 | 22.5% |
| F | 86,752 | 61.8% |
Does .sg 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 .sg doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .sg domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .sg safe?
On average, .sg is safer than the internet average: 61.8% of its 140,296 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 .sg domains?
38.2% of .sg domains score above an F and 3.7% 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 .sg 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 .sg too.
What does "grade F" mean for a .sg 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.
