How secure are United States's domains?
Most businesses in United States use a .us domain. Across 1,322,723 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-07-29.
In the .us zone — covering United States — 82.7% of 1,322,723 graded domains earn an F, well above the 73.8% internet-wide average. Only 0.2% reach an A or A+ — the highest protection tier in the census.
We use .us as a stand-in for United States, based on the domain's ending rather than where a company is legally registered — so United States businesses using a generic ending like .com aren't counted here.
Grade distribution
