How secure are European Union's domains?
Most businesses in European Union use a .eu domain. Across 1,670,955 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-07-29.
In the .eu zone — covering European Union — 57.5% of 1,670,955 graded domains earn an F, well below the 73.8% internet-wide average. DMARC enforcement here stands at 18% — above the 11.8% census-wide rate.
We use .eu as a stand-in for European Union, based on the domain's ending rather than where a company is legally registered — so European Union businesses using a generic ending like .com aren't counted here.
