How secure are Vietnam's domains?
Most businesses in Vietnam use a .vn domain. Across 511,026 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-08-16.
In the .vn zone — covering Vietnam — 80.7% of 330,947 graded domains earn an F, well above the 73.8% internet-wide average. DMARC enforcement here stands at 4.1% — below the 11.8% census-wide rate.
We use .vn as a stand-in for Vietnam, based on the domain's ending rather than where a company is legally registered — so Vietnam businesses using a generic ending like .com aren't counted here.
