TL;DR: Zero trust restricts access by default while microsegmentation limits lateral movement inside the network, and Axiad’s explainer argues the two work best when identity controls, authentication, and segment-level permissions are aligned. The real issue is that perimeter thinking and broad trust assumptions still leave room for unauthorized access and spread.
Editorial analysis by NHI Mgmt Group, based on content published by Axiad: “Zero Trust and Microsegmentation: An Explainer”.
Key questions
Q: What breaks when organisations build Zero Trust without microsegmentation?
A: Without microsegmentation, Zero Trust loses one of its main containment mechanisms.
Q: Why do segment permissions matter so much for identity security?
A: Because identity trust does not end at login.
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
- Align identity policy with segment policy Map authenticated identities, service accounts, and workloads to the exact internal resources they are permitted to reach, then remove any broader east-west access that is not required for the use case.
- Review non-human identity reachability Check service accounts, API credentials, and automation paths for internal network reach that exceeds their business function, especially where those identities can move beyond the initial application boundary.
- Separate containment from authentication Treat zero trust as the decision to grant access and microsegmentation as the control that limits what happens after that decision, so each layer is validated on its own terms.
Bottom line: Zero trust and microsegmentation address different parts of the access problem, so neither control is complete on its own.

Identity controls fail when they are treated as access gates rather than containment boundaries. Zero trust answers the question of whether access should be granted, but it does not on its own answer how far a session can move after authentication. Microsegmentation fills that second gap, which is why alignment between the two is a governance issue, not just an architecture choice. Practitioners should read these as complementary controls with different failure modes.
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.
- By 2029, 40% of enterprises that successfully implement zero trust within cloud service provider environments will rely on the advanced visibility and control capabilities offered by CNAPP solutions.
A question worth separating out:
Q: What is the difference between Zero Trust and microsegmentation in a resilience strategy?
A: Zero Trust is the broader security philosophy that assumes no implicit trust and requires verification at every stage. Microsegmentation is one of the main ways to apply that philosophy inside the network. It creates smaller trust zones so that if an intruder gains access, the breach stays contained instead of spreading to critical workloads and data.
