Cybersecurity startup Island valued at $6.4 billion amid AI agent security risks
Island, a cybersecurity startup focused on enterprise browser security, has been valued at $6.4 billion as investor attention grows around securing AI agents operating inside corporate environments.
Why this matters: AI agents need access to do their jobs. That means credentials, data, systems, and actions taken on behalf of real people. The more companies hand that access to automated tools, the bigger the question of who controls what those tools can touch. Island is betting that the browser, where most of that activity actually happens, is where the security battle will be fought. A $6.4 billion valuation suggests a lot of serious money agrees. The risk is real. The products are still catching up.
