Island, a technology company with operations in both the United States and Israel, has reached a valuation of $6.4 billion. The startup focuses on the enterprise browser market, providing software specifically engineered for businesses to manage digital security in hybrid work environments.

As companies increasingly integrate artificial intelligence agents into their daily operations, Island’s platform is designed to secure these interactions. The browser serves as a control layer, allowing organizations to monitor and protect sensitive data as employees and automated AI tools navigate web-based workflows. This valuation reflects growing investor interest in cybersecurity tools that address the unique risks posed by the modern, distributed workplace where traditional perimeter-based security is often insufficient. While the company has not disclosed the specific investors involved in this latest round, the valuation marks a significant milestone for the firm as it positions itself as a critical infrastructure provider for enterprise digital security.
