About The Company

Welcome to the Island Enterprise Platform — the ideal environment for enterprise work. For years, enterprise IT was built around layers of tools that solved real problems, but, together, fought against work instead of enabling it. Island reimagines the workspace, designing it around people, not problems, making work smooth and simple, while giving organizations complete control over how work happens. We started with the Island Enterprise Browser, embedding security, access, and control natively into the center of the workspace. But the browser was just the beginning. Today, the Island Enterprise Platform unifies the work environment into a single space with everything enterprises need: AI enablement, network, secure access, identity, data protection, and endpoint control. Not a stack, but an organic ecosystem that works as one. The world's leading banks, hospitals, airlines, retailers, manufacturers, and universities are using Island to safely embrace AI, onboard contractors in minutes, enable BYOD, reduce VDI costs, and eliminate infrastructure they no longer need. Backed by Coatue, Cyberstarts, Insight Partners, Sequoia Capital, and other elite venture funds, we're just getting started.
