The European Commission, the executive wing of the European Union, has banned TikTok from devices it owns. It also asked its staff to remove the app from personal phones and tablets that are part of its mobile device service — in other words, any devices they use for work.

“This measure aims to protect the Commission against cybersecurity threats and actions which may be exploited for cyber-attacks against the corporate environment of the Commission,” the EC said in a statement. “The security developments of other social media platforms will also be kept under constant review.”
