Team Messaging Switzerland
End-to-end encrypted team messaging, calls, and file sharing. Alternative to Microsoft Teams and Slack.
Details
Wire is a secure team-collaboration platform (Wire Swiss GmbH, Zug, under the Berlin parent Wire Group Holdings GmbH) offering channels, direct messages, voice and video calls, and file sharing with end-to-end encryption enabled by default. It ships hosted SaaS on European infrastructure, on-premise self-hosting, and a hardened high-security variant, and is widely deployed across European governments and regulated enterprises where data sovereignty and encryption are mandatory.
About Wire
Wire is a secure-collaboration platform whose contracting entity is Wire Swiss GmbH (Zug, Switzerland), operating under the German parent Wire Group Holdings GmbH (Berlin). It is European-controlled: principal shareholders include Janus Friis, Cipio Partners, the Schwarz Group, and UVC Partners, with no US controlling stake — the 2019 Delaware holding company was unwound in 2020. Wire focuses on end-to-end encrypted messaging, calls, and file sharing for enterprises and governments, with reference deployments across EU public-sector bodies and hosting on European infrastructure.
