How secure are Portugal's domains?
Most businesses in Portugal use a .pt domain. Across 350,148 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-08-16.
In the .pt zone — covering Portugal — 44.4% of 287,688 graded domains earn an F, well below the 73.8% internet-wide average. Only 0.3% reach an A or A+ — the highest protection tier in the census.
We use .pt as a stand-in for Portugal, based on the domain's ending rather than where a company is legally registered — so Portugal businesses using a generic ending like .com aren't counted here.
Grade distribution
| Grade | Domains | Share |
|---|---|---|
| A+ | 145 | 0% |
| A | 878 | 0.3% |
| B | 10,890 | 3.1% |
| C | 56,655 | 16.2% |
| D | 103,032 | 29.4% |
| F | 178,548 | 51% |
