States all across the country have banned the app in recent months.

New York City is banning TikTok from city-owned devices and requiring agencies to remove the app within the next 30 days.

The directive issued Wednesday comes after a review by the NYC Cyber Command, which a city official said found that TikTok “posed a security threat to the city’s technical networks.” Starting immediately, city employees are barred from downloading or using the app and accessing TikTok’s website from any city-owned devices.
