Cybersecurity has evolved from an IT support function to a mission-critical capability that directly impacts operational success. Today’s cyber threats move at machine speed, exploiting the gap between detection and response that has plagued traditional defense systems. This challenge becomes even more acute in Denied, Degraded, Intermittent, and Limited (D-DIL) environments—forward operating bases, tactical networks, and contested operational theaters where bandwidth is scarce, connectivity is unreliable, and cloud-based solutions simply cannot reach.
