Is .com safe? The state of .com domain security

Most .com domains can still be impersonated in email, but the ending shifts the odds, not your own domain's grade. As of 2026-07-29.

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

Frequently asked questions
Is .com safe?
On average, .com is about average for the internet: 73.7% of its 147,816,687 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 .com domains?
26.3% of .com domains score above an F and 1.9% 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 .com 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 .com too.
What does "grade F" mean for a .com 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.
