In a flat network with no segmentation, the answer is: everywhere. Every reachable host becomes a stepping stone toward high-value assets like domain controllers, databases, ERP systems, and backup servers.</p> <p><strong>Blast radius</strong> is the total number of workloads, services, and data stores an attacker can reach from an initial point of compromise. It&rsquo;s the single most important metric for understanding the actual impact of a breach &ndash; and the one most organizations can&rsquo;t quantify.</p>
