What is Island?
Founded in 2020 and headquartered in Dallas, Texas, Island provides a specialized internet browser engineered for the enterprise. Unlike traditional browsers, Island embeds security controls directly into the core of the application, allowing organizations to govern user interactions, data visibility, and application access with granular precision. This approach effectively transforms the browser into a secure workspace, mitigating risks associated with remote work, third-party access, and cloud-based application usage. By focusing on the browser as the primary interface for work, Island enables IT and security teams to enforce compliance and security policies without compromising user experience or productivity.
