The Containment Era: Building Cyber Resilience with Zero Trust and AI

The age of prevention is over. In the Containment Era, breaches are inevitable — but disasters don't have to be. This series from Illumio reveals how containment is reshaping cybersecurity from the inside out, using Zero Trust, AI-driven security graphs, and segmentation to limit the blast radius of attacks, protect hybrid environments, and keep operations resilient. Because in a world of ransomware and shadow IT, seeing threats isn’t enough — you have to contain them.
