The verdict

Crimsafe leads 40 to 38, and the gap is mostly one thing: independent testing, where it takes 21 of 25 against 0.

Bulldog Security Screens is not beaten everywhere. It is ahead on domestic manufacturing and buyer disclosure and commitment to the buyer — if that is what you are buying on, buy on it rather than on the total.

Both scores measure what each maker publishes, not laboratory strength. A system that declines to state its alloy or its price scores badly here by design, and may still be excellent steel. The installer who measures and fastens it matters at least as much as either badge.
