How secure are United States's business domains?
Most businesses in United States use a .us domain. Across 1,046,901 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-06-27.
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 a United States business on a generic ending like .com isn't counted here.
