Is .stream safe? The state of .stream domain security
.stream is riskier than the internet average. Across 18,107 graded .stream domains, 86.2% score an F — worse than the 78.3% global average — heavier on exposed domains than the web as a whole. 1.6% earn a B or better. Most .stream 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 12,581 graded .stream domains, 76.7% earn an F — above the 73.8% internet-wide average. DMARC enforcement here stands at 8.7% — below the 11.8% census-wide rate.
How do .stream domains score?
Aggregate grade distribution across all graded .stream domains — we never publish an individual business's grade. As of 2026-08-16.
| Grade | Domains | Share |
|---|---|---|
| A+ | 11 | 0.1% |
| A | 37 | 0.2% |
| B | 238 | 1.3% |
| C | 753 | 4.2% |
| D | 1,460 | 8.1% |
| F | 15,608 | 86.2% |
Does .stream 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 .stream doesn't protect you, and a high-F-share ending doesn't doom you: a correctly configured .stream domain earns an A while the crowd around it sits at F.

Frequently asked questions
Is .stream safe?
On average, .stream is riskier than the internet average: 86.2% of its 18,107 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 .stream domains?
13.8% of .stream domains score above an F and 1.6% 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 .stream 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 .stream too.
What does "grade F" mean for a .stream 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.
