How secure are Switzerland's domains?
Most businesses in Switzerland use a .ch domain. Across 1,959,486 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-08-16.
In the .ch zone — covering Switzerland — 34.6% of 1,428,565 graded domains earn an F, well below the 73.8% internet-wide average. DMARC enforcement here stands at 33.2% — above the 11.8% census-wide rate.
We use .ch as a stand-in for Switzerland, based on the domain's ending rather than where a company is legally registered — so Switzerland businesses using a generic ending like .com aren't counted here.
