I haven’t looked into VyprVPN! I have looked into Telegram.

Telegram’s pretty easy to use, so I understand why people like it. But when I ask security experts, they suggest alternatives because Telegram does not use end-to-end encryption by default and some of its encryption has significant security flaws. There have also been a few documented cases of journalists’ Telegram accounts being hijacked via SMS. More on that here:

In the end, they lean toward Signal or WhatsApp, but Signal is a lot more careful about data retention and metadata. More here:
