Compared to other forms of communication, IM is less secure because it uses a public network. Instant messaging conversations can be easily copied and pasted, which might lead them to fall into the wrong hands. There are further weaknesses related to authentication and passwords, which make it possible for information to reach the wrong people.
However, some instant messaging apps are more secure than others, which is why Brosix is one of the best options out there. Our solution is encrypted end-to-end on all communication channels, keeping communication private and worry-free.
