How secure are Bulgaria's domains?
Most businesses in Bulgaria use a .bg domain. Across 67,364 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-07-29.
In the .bg zone — covering Bulgaria — 36.9% of 67,364 graded domains earn an F, well below the 73.8% internet-wide average. Only 0.2% reach an A or A+ — the highest protection tier in the census.
We use .bg as a stand-in for Bulgaria, based on the domain's ending rather than where a company is legally registered — so Bulgaria businesses using a generic ending like .com aren't counted here.
Grade distribution
| Grade | Domains | Share |
|---|---|---|
| A+ | 17 | 0% |
| A | 138 | 0.2% |
| B | 2,195 | 3.3% |
| C | 10,065 | 14.9% |
| D | 30,121 | 44.7% |
| F | 24,828 | 36.9% |
