Reading the United States of America number

193,631 is the number of ranked websites in Hunter's index that were detected running HSTS and carry a United States of America company address. It is a floor, not a vendor's customer list, and the address is where the business is registered rather than where the site is served from.

A detection describes what a site runs today, and a tag left in place after a team stopped paying still counts — so treat one detection as a lead to check rather than as a confirmed contract.

See HSTS worldwide for the full count, the technologies it turns up alongside, and every country Hunter ranks it in.
