This solution brief explains how modern cyberattacks cause the most damage after initial access, as attackers move laterally across hybrid environments to reach critical systems. It highlights challenges such as limited visibility into internal traffic, increasing complexity from multi-cloud and IT/OT convergence, and the inability of perimeter-based tools to stop internal threats. Illumio addresses this with a unified platform combining real-time visibility and Zero Trust segmentation to detect, prioritize, and contain threats quickly. It enables organizations to map workload communication, identify high-risk attack paths, and isolate compromised systems instantly without disrupting operations. The key takeaway is that organizations must focus on breach containment—using visibility and se
