All communication through Wire is secured with end-to-end encryption — messages, conference calls, files.
Wire is the most extensively publicly audited collaboration and communication software on the market.
One account works on up to 8 devices. Messages are encrypted for each device.
Verify each conversation partner’s device fingerprints for maximum security.
New encryption keys are used for each message, so a compromised key has minimal impact.
Wire’s source code is available on GitHub for anyone to verify, modify and improve.
Text messages and pictures use the Proteus protocol for end-to-end encryption. Proteus is based on the Axolotl ratchet and pre-keys that are optimized for mobile and multi-device messaging.
Voice and video calls use the WebRTC standard. More precisely, DTLS and KASE are used for key negotiation and authentication and SRTP is used for encrypted media transport. This means that voice calls are end-to-end encrypted with perfect forward secrecy enabled without compromising HD call quality.
Wire’s encryption works transparently in the background and doesn’t need to be activated — it’s always on. There’s no need to compromise security for usability or settle for missing features. Wire keeps everything private while avoiding the complexity that is common to other secure messengers.
We store only the data we need to make sure your conversations stay in sync across devices, to detect fraud and spam, and to troubleshoot customer issues.
Wire is fully GDPR compliant and helps its customers to deal with the requirements of GDPR. By encrypting all communication we ensure that no sensitive data is available to Wire as a 3rd party thus reducing the number of data processors a business needs to deal with.
Wire’s source code is available on GitHub with a GPLv3 licence. A self-hosted server option will be available for business customers in 2018.
Wire publishes a regular transparency report detailing all lawful requests for user data.
Wire does not sell its users’ data. We make money from paying customers and don’t rely on donations.
