How secure are Thailand's domains?
Most businesses in Thailand use a .th domain. Across 55,441 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-07-29.
In the .th zone — covering Thailand — 47.4% of 55,441 graded domains earn an F, well below the 73.8% internet-wide average. DMARC enforcement here stands at 17.4% — above the 11.8% census-wide rate.
We use .th as a stand-in for Thailand, based on the domain's ending rather than where a company is legally registered — so Thailand businesses using a generic ending like .com aren't counted here.
