Enterprise security company Island said it raised $400 million in a Series F round that brought its valuation to $6.4 billion. Evolution Equity Partners led the financing, which included returning investors Sequoia Capital, Coatue Management and Cyberstarts. Island said it will use the funds to expand controls for employees and AI agents working across browsers, devices, networks and data. The company says it employs 1,000 people and has doubled annual recurring revenue in each fiscal year since its 2022 launch. Island has previously said its research and development center is in Tel Aviv.
