The top three safest messengers include Signal, Wickr and Viber, which is ahead of Telegram. Signal Messenger continues to receive high praise from experts for the quality of its encryption protocols,
presence of two-factor identification, encryption by default and readiness to disclose personal data. Elon Musk’s calls to switch to Signal look reasonable.

Among the significant changes in the results of testing messengers, which were conducted by Artezio in 2018, experts noted the improvement in the positions of Viber and iMessage. So, Viber following the results
Telegram moved up to 4th place in tests, and Apple’s iMessage is ahead of WhatsApp by a significant margin. Facebook messenger maintains its place in the ranking of the safest browsers, even despite
scandal with updated user agreement. Experts have previously pointed out that the messenger transmits all information to Facebook. However, the new user agreement should have forced
share data of users who previously explicitly prohibited it from doing so.

Experts do not recommend using Facebook messengers for business correspondence or sending private information.

Line dropped out of the list of the best messengers compiled in 2018, it does not meet the criteria for safe messengers. He was replaced by Slack, which the experts
confidently recommend for secure corporate communications.

Despite expectations, Telegram continues to lose its position in the ranking of secure communication applications. Previously, it was ahead of Viber, but following the results of actual testing, it lost to development
by Rakuten.

The research participants note an unconditional improvement in the quality of user data protection in popular messengers. However, experts are concerned about the slowdown in the development of independent
solutions that could use new approaches and tools to ensure data security and privacy of correspondence.
