How secure are South Korea's business domains?
Most businesses in South Korea use a .kr domain. Across 378,881 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-06-27.
We use .kr as a stand-in for South Korea, based on the domain's ending rather than where a company is legally registered — so a South Korea business on a generic ending like .com isn't counted here.
Grade distribution
