Wire is an enterprise-grade secure communications platform providing encrypted messaging, voice/video calls, and file collaboration. It uses MLS (Messaging Layer Security) encryption, described as always-on and zero-knowledge, meaning the provider cannot access user data. The platform targets three primary segments: - Business: Teams needing secure messaging, file sharing, and document collaboration with data ownership controls. - Enterprise: Organizations requiring SAML-based single sign-on (SSO), SCIM provisioning, and granular administrative controls for complex structures. - Government: Public authorities and law enforcement needing total data sovereignty, federated environments, ID Shield protection, and on-premises deployment. Key security and compliance capabilities include zero-knowledge encryption, compliance with strict regulatory standards, and support for on-premises deployment. The platform is trusted by organizations including the US Air Force, BMW, EY, BSI (German Federal Office for Information Security), Greenpeace, and Médecins Sans Frontières, among others.
