Best Microsegmentation Software in 2026
Facts read from the makers 22 Sept 2026 – 15 Oct 2026
Microsegmentation tools help define boundaries for communication among workloads. When comparing options, consider policy granularity and identity-based rules, along with workload coverage and Kubernetes enforcement. Cloud environment and deployment model can help you assess where an option fits, while policy simulation offers another listed point of comparison. The entries also specify whether a free plan is available and the paid starting price. ColorTokens Xshield, Calico Open Source and Istio are among the named options, alongside VMware Workstation Pro and Cilium. Check the listed controls and environment details against the workloads and infrastructure you need to manage.
