Cross-functional security requires breaking down organizational silos

Flannery argues that security threats are systemic organizational problems masked by departmental isolation, and that only cross-functional collaboration can surface the warning signs that single-department decision-making inevitably misses. He advocates for security governance that includes stakeholders from operations, IT, facilities, and management—not as advisors, but as essential participants whose diverse perspectives reveal vulnerabilities before they become breaches.
