It was a test of how a global building-technology supplier proves resilience when its internal systems, customer-facing platforms, product assurance obligations and public-facility customers all sit close to the same trust boundary. The accountable question is who controlled segmentation, restoration evidence, customer continuity, disclosure timing and the practical assurance needed by hospitals, schools, public agencies, integrators, building owners and investors.
