For companies expanding globally, securing digital assets while maintaining resilience is a major challenge. Tokio Marine Group faced difficulties unifying security across diverse subsidiaries with unique ”federated governance” policies. To address this, it established the Global Fusion Center (GFC)—a virtual organization focused on 1)standardized services, 2)a consistent security architecture, and 3) virtual CISOs/staffs to support group companies.

This session will explore the GFC’s strategy, key initiatives, implementation challenges, and the developing the organizational structure. Attendees will learn about obstacles faced, lessons learned, and how the GFC strengthens security resilience.

The GFC demonstrates how a centralized yet flexible security framework can enhance global resilience while accommodating local needs. Participants will gain insights into overcoming resource constraints, and aligning regional operations for unified security practices.

Learning Objectives:

Participants will understand how to balance global security consistency with local flexibility using a federated governance model. They will explore GFC’s practical approach, including standardized services, scalable architecture, and virtual CISOs, gaining insights into securing diverse global subsidiaries with unique policies and constraints.
Participants will gain practical lessons from GFC’s journey, including overcoming resource limitations, organizational resistance, cultual difference, and alignment issues. The session will highlight real-world strategies for navigating security governance complexities, ensuring effective collaboration between global and regional teams while maintaining a unified security approach.
Attendees will understand how the GFC enhances global security resilience by leveraging virtual teams, streamlining threat intelligence sharing, and optimizing security operations. The session will provide actionable takeaways on scaling security frameworks efficiently, even in large, decentralized organizations with diverse operational needs.
