Some privacy experts say Telegram is not secure enough The regulator said it has been undertaking several campaigns to educate the investors to be vigilant while taking investment decisions based on stock tips. Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. In 2018, Russia banned Telegram although it reversed the prohibition two years later. Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting. Standard conversations use the MTProto method, enabling server-client encryption but with them stored on the server for ease-of-access. 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.
