Pros

    Island

    As enterprises enter the agentic era, legacy architectures can no longer keep up. The future of work demands a new foundation, one where the user, whether agentic or human, is at the center of the design. The Island Platform is that foundation: The frontier control plane that simultaneously enables, governs, and protects both human and AI workers leveraging endpoint, network, data, and identity. This fabric dramatically reduces the cost and complexity of IT while improving overall security, observability, and productivity.
