This resource is a practical handbook from Cyware that outlines how U.S. states and territories can strengthen cybersecurity through a whole-of-state collective defense model. It explains how state governments can centralize threat intelligence, automate sharing and response and connect agencies, local governments, schools, utilities and other public entities through a hub-and-spoke architecture to improve cyber resilience. The guide also includes readiness assessments, governance frameworks, implementation roadmaps and funding considerations to help states build and operationalize statewide cyber defense programs.
