Simple, secure, private—always end-to-end

Our personal and professional data is at the center of a new economy. The information we share on social networks, via email, and messaging services is being used to build profiles. These profiles are in turn used to sell us products and services through targeted advertising and suggestion. The data collected is vast, detailed, and often very personal. Vast resources are being spent to refine the profiles, all without transparency, policy or oversight.

Our personal and professional online communications should not be part of this economy. In the physical world we talk with each other directly. We can lower our voices or close a door to share private thoughts. In the online world we should be able to communicate directly without passing our private communications through these corporate data mines.

Wire is different.

No ads

Banners, popups, takeovers — none of that.

No profiling

Wire does not sell your usage data to advertising companies.

Full end-to-end encryption

By far the best way to protect any conversation on any device.

The concept

All Wire applications across all platforms uniformly use state-of-the-art encryption mechanisms that are recognized as reliable by experts and the community.

Text, voice, video and media on Wire are always end-to-end encrypted 1:1 and in groups, so all your conversations are secure and private. Conversations are available on multiple devices and platforms without weakening security.

Conversation content is encrypted with strong encryption on the sender’s device and only decrypted on the recipient’s device. Wire doesn’t hold the decryption keys and our software contains no backdoor. Your data is your data — Wire has no access to it.

Users who wish to do so can always verify the digital identity of other users thanks to fingerprint comparison.

Technical overview

Text messages and pictures use Off-the-Record (OTR) end-to-end encryption. Wire uses the Axolotl ratchet and pre-keys which are optimized for mobile messaging.

Voice calls use the WebRTC standard. More precisely DTLS is 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.

The encryption works transparently in the background and doesn’t need to be activated first. It doesn’t get in the way of usability or reduce the feature set and avoids the complexity that is common to secure messengers.

Transparency

Our commitment to security is entirely verifiable — you don’t have to take our word for it.

Wire uses open-source cryptography to encrypt all content. We made the source code for data handling available to the public under the GPL License. This means that anybody can review the source code.

Wire regularly publishes Transparency Reports in which we disclose details about requests from law enforcement.

Wire is not financed by ads. Your personal data or the content of your conversations are never sold or rented to anyone, and it will not be used for any third party advertising.

Wire is based in Switzerland and is fully compliant with Swiss and EU data protection laws.
