Microsegmentation cuts ransomware spread by 80% in 2024 enterprise tests by enforcing least-privilege controls at the workload level. The mechanism is simple: restricting east-west traffic prevents attackers from moving laterally once initial access is gained. In controlled simulations across multiple enterprise environments, including tests aligned to NIST guidance, organisations observed significant reductions in compromised systems when segmentation policies were applied. For practitioners, this means containment becomes measurable and predictable, shifting security from detection-centric models to architectures that actively limit blast radius during real incidents.
