TL;DR: Combining microsegmentation with identity-driven ZTNA can reduce lateral movement and keep access aligned as environments change, according to ColorTokens. The control model is only as strong as policy synchronisation, because drift turns segmentation into an incomplete containment layer.
Editorial analysis by NHI Mgmt Group, based on content published by ColorTokens: “It’s an East-West, North-South Thing: ColorTokens and Netskope Have You Covered from All Directions”.
Key questions
Q: What breaks when microsegmentation and ZTNA policy are not kept in sync?
A: When segmentation and access policy drift apart, users or services can retain valid paths to systems that should no longer be reachable.
Q: Why does policy drift increase lateral movement risk in dynamic environments?
A: Policy drift leaves internal pathways open after the environment has changed, so an attacker who gains one foothold can still traverse to other systems.
Q: How do teams know if microsegmentation is actually working?
A: Microsegmentation is working when a compromised workload cannot reach anything outside its explicit policy boundary.
Practitioner guidance
- Map workload lifecycle events to access revocation Tie server creation, retagging, movement, and decommissioning to immediate updates in ZTNA and segmentation policy so stale access does not persist after topology changes.
- Automate policy sync from a single source of truth Use one authoritative inventory for workloads, tags, and protected resources so both network segmentation and application access rules are updated by the same change event.
- Test containment after compromise scenarios Run exercises where a compromised server is moved or quarantined and verify that user access disappears quickly enough to stop lateral movement.
Bottom line: Microsegmentation and identity-driven ZTNA only reduce lateral movement when policy changes follow workload and resource changes.

Policy synchronisation is the real control plane problem in Zero Trust. Microsegmentation and identity-driven ZTNA are often discussed as separate layers, but the article shows that their value depends on how quickly they converge when environments change. Without synchronised updates, containment and access control drift apart. Practitioners should treat policy sync as a governance requirement, not an implementation detail.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Who should own synchronization between identity policy and segmentation policy?
A: Ownership should be shared across IAM, cloud operations, and security engineering, because the change that creates risk is usually operational, not purely technical. Identity policy and segmentation policy need a common change process and a single authoritative inventory. Without that, each team can be compliant in isolation while the overall control fails.
