How secure are Spain's domains?
Most businesses in Spain use a .es domain. Across 1,149,346 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-07-29.
In the .es zone — covering Spain — 55.6% of 1,149,346 graded domains earn an F, well below the 73.8% internet-wide average. DMARC enforcement here stands at 14.8% — above the 11.8% census-wide rate.
We use .es as a stand-in for Spain, based on the domain's ending rather than where a company is legally registered — so Spain businesses using a generic ending like .com aren't counted here.
