Individual messages can be fully encrypted. But the user has to turn on that function. It's not automatic, as it is on Signal and WhatsApp. Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting.

This makes using Telegram across multiple devices simple, but also means that the regular Telegram chats you’re having with folks are not as secure as you may believe.

In 2018, Russia banned Telegram although it reversed the prohibition two years later.
