How secure are Slovakia's domains?
Most businesses in Slovakia use a .sk domain. Across 291,361 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-07-29.
In the .sk zone — covering Slovakia — 40.2% of 291,361 graded domains earn an F, well below the 73.8% internet-wide average. DMARC enforcement here stands at 18.3% — above the 11.8% census-wide rate.
We use .sk as a stand-in for Slovakia, based on the domain's ending rather than where a company is legally registered — so Slovakia businesses using a generic ending like .com aren't counted here.
