Finding
01Why Tanzania received this score.
Election and protest restrictions, arrests of critics, broad communications controls, surveillance concerns, and weakened remedies substantially constrain online freedom.
The score draws on country reporting, network measurements, shutdown records, journalist cases, privacy law, and rule-of-law data. The indicator findings below show how that evidence was converted into points. [1][2][3][4][5][6][7][8]
Privacy, Anonymity & User Security
Broad surveillance powers and limited independent authorization weaken privacy and anonymity.
Rule of Law & Accountability
Oversight and remedies are weak, selective, or difficult to use against state digital powers.
