Zero Trust Has a Policy Governance Problem: Why Segmentation Fails Without Continuous Policy Control

Zero Trust architectures often fail not due to lack of enforcement technology but due to inadequate continuous policy governance. As enterprises layer microsegmentation, ZTNA, cloud controls, and firewalls across hybrid environments, policy complexity compounds. Temporary exceptions accumulate, rules go stale, ownership becomes unclear, and policy drift quietly erodes security posture. The core argument is that enforcement controls traffic while governance determines whether policies remain accurate and aligned with business intent. Organizations need a centralized control plane to detect drift, validate changes, and maintain consistency across multi-vendor, hybrid infrastructure — otherwise even well-designed Zero Trust deployments degrade over time. FireMon is presented as a solution for continuous policy governance across these environments.
