Overall Safety Score

Verdict: Telegram is widely perceived as secure, but its default chats are only encrypted in transit, not end-to-end. Secret Chats offer E2E encryption but are not the default and not available for groups. This is a critical distinction.
Telegram is a cloud-based messaging platform with over 800 million users known for large groups, channels, and bots. Despite its privacy-focused reputation, regular chats are not end-to-end encrypted by default.
