This solution brief explains how emerging quantum computing capabilities threaten traditional encryption through “harvest now, decrypt later” attacks. It highlights that once encryption fails, attackers can move laterally across unsegmented systems. The joint Illumio and IBM solution combines quantum-safe cryptography with segmentation to contain threats even if encryption is compromised. It provides visibility into communication flows, enforces workload isolation, and detects anomalies in real time. The brief emphasizes a dual-layer defense: IBM prepares organizations for quantum-safe cryptography while Illumio ensures immediate breach containment. The key takeaway is that organizations must combine future-ready encryption strategies with segmentation to protect systems against both curre
