How secure are South Korea's domains?
Most businesses in South Korea use a .kr domain. Across 415,206 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-07-29.
In the .kr zone — covering South Korea — 88.2% of 415,206 graded domains earn an F, well above the 73.8% internet-wide average. DMARC enforcement here stands at 1.8% — below the 11.8% census-wide rate.
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 South Korea businesses using a generic ending like .com aren't counted here.
