How secure are Tanzania's business domains?
Most businesses in Tanzania use a .tz domain. Across 29,714 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-06-27.
We use .tz as a stand-in for Tanzania, based on the domain's ending rather than where a company is legally registered — so a Tanzania business on a generic ending like .com isn't counted here.
Grade distribution
| Grade | Domains | Share |
|---|---|---|
| A+ | 0 | 0% |
| A | 4 | 0% |
| B | 96 | 0.3% |
| C | 1,273 | 4.3% |
| D | 5,319 | 17.9% |
| F | 23,022 | 77.5% |
