Is .sc safe? The state of .sc domain security
.sc is safer than the internet average. Across 3,300 graded .sc domains, 72% score an F — cleaner than the 78.3% global average — better company than most of the web. 3.2% earn a B or better. Most .sc domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-08-16.
Of 3,300 graded .sc domains, 72% earn an F — well below the 78.3% internet-wide average. Only 0.4% reach an A or A+ — the highest protection tier in the census.

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

Frequently asked questions
Is .sc safe?
On average, .sc is safer than the internet average: 72% of its 3,300 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 .sc domains?
28.0% of .sc domains score above an F and 3.2% 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 .sc 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 .sc too.
What does "grade F" mean for a .sc 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.
