Wire provides physical, electronic, and procedural safeguards to protect your information.
Wire uses end-to-end encryption for all messages, media, and calling. We use Secure Real-Time Transport Protocol (SRTP) with Datagram Transport Layer Security (DTLS) for end-to-end calling encryption.
See Wire’s Security Whitepaper and Privacy Whitepaper for more details about the encryption methods Wire uses and about how Wire protects your privacy.
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.
