Is .lk safe? The state of .lk domain security — Sri Lanka
.lk is safer than the internet average. Across 44,639 graded .lk domains, 48.9% score an F — cleaner than the 73.8% global average — better company than most of the web. 2.2% earn a B or better. Most .lk domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-07-29.
Note: .lk is used as a proxy for Sri Lanka based on the domain's TLD, not where the company is registered.
How do .lk domains score?
Aggregate grade distribution across all graded .lk domains — we never publish an individual business's grade. As of 2026-07-29.

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

Frequently asked questions
Is .lk safe?
On average, .lk is safer than the internet average: 48.9% of its 44,639 graded domains score an F as of 2026-07-29, against a 73.8% global average. Most domains on every ending are exposed — the ending shifts the odds, not your own domain's grade.
How secure are .lk domains?
51.1% of .lk 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 .lk 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 .lk too.
What does "grade F" mean for a .lk 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.
