Island Raises $400M for Enterprise Agent Control
Island raises a large Series F as the enterprise browser becomes a control point for data, identity and agentic workflows.
Enterprise browsers are becoming a security control point as work moves through cloud apps, SaaS tools and AI agents.
What happened
Island raised a $400 million Series F at a $6.4 billion valuation, more than doubling its valuation since 2024.
The company positions its enterprise browser as a control plane for work, letting organisations manage data access, identity, security policies and workflows at the point where employees actually interact with applications.
Island has increasingly framed that layer as relevant to agentic work as well as human browsing.
Why it matters
Traditional enterprise security often sits around devices, networks or individual applications. But modern work happens inside browsers across many SaaS tools.
If AI agents begin acting inside those same environments, companies need ways to control what can be accessed, copied, automated or executed.
Island’s funding suggests investors see the browser as a strategic enforcement layer for both employees and AI-driven workflows.
The bigger picture
The rise of agents is reshaping enterprise security architecture.
Companies need governance where work happens, not only at the perimeter. That creates room for control-plane products that combine browsing, identity, policy, data protection and automation oversight into one operational layer.
