All communication through Wire is end-to-end encrypted — messages, conference calls, and files. Each message is encrypted with a new key. No one, except the participants in a conversation can decrypt information. Wire’s encryption works transparently in the background and doesn’t need to be activated — it’s always on.

Note
Using the Wire Drive feature: Messages and calls are always end-to-end encrypted, whereas files and folders are secured in transit and encrypted at rest.
