The small number of employees at the Telegram app has raised serious concerns among security experts.
In a recent interview, Pavel Durov mentions that only about 30 engineers work at Telegram and almost all tasks are handled by these individuals. He notes that he himself is active as the product manager at Telegram and personally monitors the performance of the employees closely.
Matthew Green, a cryptography expert from Johns Hopkins University, mentions in an interview that the lack of end-to-end encryption, the servers located in the United Arab Emirates, and the presence of potential targets in this messaging app have turned it into a serious security threat for users.
