Island: Hits $6.4B Valuation on AI Attack Surge

Island closed a round that values the cyber startup at $6.4 billion, with AI-driven attacks accelerating enterprise security budgets. The deal reflects how attackers now deploy machine learning at scale, forcing companies to match that speed with new defensive tools. Island supplies browser-based isolation that blocks threats at the endpoint, a direct response to the surge in automated exploits seen over the past year.
