Like Telegram, Viber has joined the common struggle for the security of personal data. The operating director of the messenger, Michael Shmilov, said that Viber would not be able to provide the FSB with encryption keys.
Correspondence inside Viber is protected by end-to-end encryption, which does not allow the company to provide keys, even if they wanted it. By this refusal in the Russian Federation, Telegram has been banned for the second time.
If things continue in the same vein and the European court cannot change anything, maybe there will not be any messengers in Russia at all. Although no one has raised any claims to Viber. For whom do you worry more and who do you trust more? Viber or Telegram?50
