About Wire
Founded in 2012 by Janus Friis, co-founder of Skype, Wire has become Europe’s leading secure communications platform, trusted by more than 1,800 organisations and over 20 million users worldwide. In 2025, the company recorded an impressive 85% year-over-year revenue increase, alongside 60% growth through May alone, a clear sign of the rising global demand for sovereign, transparent, and compliant communication tools across both public and private sectors. Leading enterprises such as the Schwarz Group, one of Europe’s largest retail organisations, rely on Wire to ensure secure and compliant collaboration across their global operations. As Schwarz Group notes, “What we value most is that Wire combines maximum security and sovereignty with simplicity at scale. Whether it’s a Lidl store employee or a team at headquarters — anyone can use it, securely and easily. Wire is not only secure against eavesdropping, it’s also resilient against outages.”
Wire stands apart from competitors through its implementation of Message Layer Security (MLS), a breakthrough encryption standard developed by the Internet Engineering Task Force. As a founding contributor to the protocol — alongside organisations such as Mozilla, Cisco, Google and Meta — Wire became the first and remains the only company to implement MLS across an entire collaboration platform. This encompasses messaging, voice, video conferencing and file sharing, delivering secure and scalable collaboration for up to 2,000 participants at once.
Traditional encryption models were never built for the complexity and scale of modern enterprise communication. Wire helped overcome this challenge by co-developing and deploying the Messaging Layer Security (MLS) protocol, a next-generation standard that replaces outdated one-to-one encryption with a scalable, tree-based system known as TreeKEM. This ensures efficient, secure communication even as users join or leave conversations, with automatic key refreshes providing post-compromise protection and future-readiness for post-quantum encryption.
Building on this foundation, Wire’s strategic acquisition of Pydio in late 2024, a leading secure enterprise content management platform, has expanded its capabilities beyond messaging to deliver a comprehensive, end-to-end collaboration solution. The acquisition strengthens Wire’s position in regulated industries, enabling customers to deploy a fully sovereign stack for content management, sharing, and automation with uncompromising security.
Beyond encryption, Wire integrates critical features such as ID Shield for automated user and device verification, and federation support for encrypted collaboration between separate organisations. These capabilities make Wire the preferred choice for high-compliance sectors including defence, finance, healthcare and critical infrastructure.
Transparency has been a guiding principle since Wire’s inception. The company’s entire codebase is open source and publicly available on GitHub, allowing for independent audits and continuous third-party validation. Hosting infrastructure in Germany and Ireland ensures full alignment with GDPR and the European Union’s data sovereignty agenda. For customers needing total control, Wire also offers on-premises deployment options.
