Wire (software)

[23][24] In 2018, Wire launched its collaboration solution featuring end-to-end encrypted chat, conferencing, video calls and file-sharing on desktop and mobile for businesses.

[25] Wire offers end-to-end encrypted messaging, file-sharing, video and voice calls, and guest rooms for external communication.

[33] Wire's secure guest rooms feature extends end-to-end encryption to conversations with external parties without requiring them to register, or even download anything.

[39] In 2016, during the IETF meeting in Berlin, Wire proposed a standard that was protected by modern security properties and could be used by companies large and small.

These included a man-in-the-middle attack on voice and video communications, possible audio and video leakage depending on unspecified codec parameters, the fact that all user passwords are uploaded to Wire's servers, significant attack surface for code replacement in the desktop client, and the fact that the server was not open-sourced, at the time when that article was written.

"[47] However, one major issue that remained was detailed as "the Wire client authenticates with a central server in order to provide user presence information.

The Wire whitepapers spend an unusual amount of space discussing the engineering details of this part of the protocol.

"[47] On 9 February 2017, Kudelski Security and X41 D-Sec published a joint review of Wire's encrypted messaging protocol implementation.

"[50] The report also recommended that other security improvements be implemented to address thread-unsafety risks and sensitive data in memory.

[52] In May 2017, Motherboard published an article saying that the Wire servers "keep a list of all the users a customer contacted until they delete their account".

[53] Wire Swiss confirmed that the statement was accurate, saying that they keep the data in order to "help with syncing conversations across multiple devices", and that they might change their approach in the future.

[53] In July 2019, Wire won Capterra's Best Ease of Use award[54] in the team communication software category for its B2B solution.

[22] In July 2017, Wire Swiss announced the beta version of an end-to-end encrypted team messaging platform.
