How secure are Iceland's domains?
Most businesses in Iceland use a .is domain. Across 60,954 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-08-16.
In the .is zone — covering Iceland — 49% of 49,116 graded domains earn an F, well below the 73.8% internet-wide average. Only 0.7% reach an A or A+ — the highest protection tier in the census.
We use .is as a stand-in for Iceland, based on the domain's ending rather than where a company is legally registered — so Iceland businesses using a generic ending like .com aren't counted here.
Grade distribution
| Grade | Domains | Share |
|---|---|---|
| A+ | 122 | 0.2% |
| A | 253 | 0.4% |
| B | 1,923 | 3.2% |
| C | 7,392 | 12.1% |
| D | 14,125 | 23.2% |
| F | 37,139 | 60.9% |
