Wire is a secure messenger and collaboration platform built for organizations that cannot afford leaks, exposure, or loss of control. We help governments, critical infrastructure, and enterprises replace insecure messaging, reduce shadow IT, and take back control of their communications. It brings together messaging, voice, video, and file sharing in one workspace, protected by strong, always on end to end encryption. ❌ The reality today Most collaboration tools were not designed for security. They expose data, create dependency on non sovereign providers, and leave gaps in compliance. ✅ What Wire does differently – End to end encryption is always on across messages, calls, and files – No one can access your data, not even Wire – Flexible deployment across EU cloud, private cloud, on prem, or air gapped environments – Encryption based on the Messaging Layer Security standard, built to scale without friction Unlike traditional tools, Wire is built so that security does not depend on trust in the provider. It removes data access, reduces sovereignty risk, and gives organizations full control over their communications. ➡️ Where it matters most – Crisis and incident communication – Confidential workflows across legal, executive, and security teams – Frontline and cross organization coordination without consumer apps ✅ The result Secure, sovereign collaboration your teams can actually use without compromise. Book a demo and see how Wire fits into your security and IT environment and replaces insecure communication tools.
