About Island
At a glance
Island is a cybersecurity company specializing in Endpoint Security, founded in 2020 and headquartered in Dallas, United States. It has raised $810M in total funding, employs about 1,226 people, and is privately held.
Island develops an enterprise browser that embeds security, IT controls, data protections, and application access directly into the browsing experience. The company's browser is designed to address enterprise security and productivity needs by integrating advanced security controls, network protections, and IT management capabilities into a single platform rather than relying on external tools. The enterprise browser serves as a workspace where organizations can manage secure access to SaaS and web applications while maintaining control over data and user activities. Island's solution addresses use cases including BYOD workforce management, third-party contractor access, M&A onboarding, VDI reduction, privileged access management, and zero trust implementations. The platform targets large enterprises across multiple industries including healthcare, government, higher education, financial services, and business process outsourcers. Island's approach focuses on embedding security and IT controls natively into the browser rather than layering them on top of existing browsers. The company is headquartered in Dallas with research and development operations in Tel Aviv. Island raised $175 million in Series D funding in 2024, reaching a valuation of $3 billion. The company is backed by investors including Coatue Management, Sequoia Capital, Insight Partners, Cyberstarts, Stripes, Cisco Investments, Georgian, Prysm, and Canapi. Island was co-founded by Mike Fey, who serves as CEO.
