We operate as a non-retained, on-call crisis response provider for select international firms, ready for rapid surge deployment. Our approach is designed to integrate flexibly into existing teams, whether embedded directly into client operations or white labeled through our associate partnerships. All client information is treated as strictly confidential. This model allows for discretion, agility, and tailored delivery in high-stakes environments.

Fortis Advisory’s operational experience spans Sub-Saharan Africa, the Middle East and Asia, providing a foundation for deployment wherever client needs arise. The firm supports swift mobilisation across Southeast Asia from its base in Vietnam, a centrally located and well-connected hub with a dynamic business environment. Principal Consultant Ruben Hoornveld resides in Ho Chi Minh City with his family, ensuring a stable and responsive presence in the region.

We work with a small number of trusted crisis response firms and uphold strict confidentiality, non-disclosure, and conflict-of-interest commitments for every engagement. Assignments are accepted only when they can be delivered without any conflict of interest, and client information is always treated as strictly confidential. No proprietary material, internal practice, or sensitive detail is ever shared between clients. Workload and project sequencing are managed to ensure full independence, focus, and discretion for every client.

Ruben Hoornveld is the Principal Consultant of Fortis Advisory, a trusted partner for high-stakes crisis response. A former Army Officer with 18 years of service and two Afghanistan tours, he has since led security operations and advised CEOs in over 35 countries, mostly in high-risk contexts. Known for quiet competence under pressure, he supports organisations needing rapid, tailored support. Ruben brings a calm and operationally tested perspective to every client engagement.
