How secure are European Union's business domains?
Most businesses in European Union use a .eu domain. Across 1,556,540 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-06-27.
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 a European Union business on a generic ending like .com isn't counted here.
