Is .systems safe? The state of .systems domain security
.systems is safer than the internet average. Across 41,423 graded .systems domains, 75.3% score an F — cleaner than the 78.3% global average — better company than most of the web. 3.3% earn a B or better. Most .systems 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 37,943 graded .systems domains, 76.1% earn an F — above the 73.8% internet-wide average. DMARC enforcement here stands at 17.6% — above the 11.8% census-wide rate.

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

Frequently asked questions
Is .systems safe?
On average, .systems is safer than the internet average: 75.3% of its 41,423 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 .systems domains?
24.7% of .systems domains score above an F and 3.3% 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 .systems 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 .systems too.
What does "grade F" mean for a .systems 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.
