Most organizations assume IT owns cybersecurity, but that assumption creates a cyber governance gap that exposes the business to real cyber risk. When IT is consumed by business process demands, security monitoring slips, alerts go ignored, and incidents escalate.

Drawing on negligence law, regulatory enforcement, and compliance principles, it offers boards a roadmap to achieve defensibility, accountability, and proportional safeguards.
