Wire
Secure messenger for organizations with end-to-end encryption.
Wire is an open-source secure collaboration platform that combines messaging, calling, conferencing, file sharing, and document collaboration with always-on end-to-end encryption. It addresses the need for organizations to communicate and work together while keeping data private and compliant, including administrators and operators who cannot read message content.
Core capabilities include group messaging with sketches, reactions, and audio/video messages; audio and video conferencing for up to 150 participants with screen sharing and moderation; Wire Drive for file management and document collaboration; and self-deleting messages. Security is built on Messaging Layer Security (MLS), with ID Shield for device verification, federation across separate backends, multi-tenancy, and SCIM provisioning with SAML-based single sign-on. It runs on web, desktop, and mobile, supporting up to 8 devices and 3 simultaneous accounts per device.
Wire targets enterprises, governments, public authorities, and law enforcement, with on-premises and cloud deployment options. The platform is offered through a free starting option alongside enterprise and government editions, with sales-led contact for organizational plans.
