Zero Trust Network Access: A Phased Adoption Plan

Replace broad network trust gradually by prioritizing applications, identity signals, device posture, and observable access policy.

Choose a Bounded Starting Point

Begin with a well-understood application and user group. A bounded pilot makes dependencies, policy gaps, and support needs easier to observe.

Build Policy From Reliable Signals

Combine verified identity, device health, application sensitivity, and session context. Policy must degrade safely when a supporting signal is unavailable.

Retire Legacy Access Deliberately

Measure adoption and remove bypass paths once users can complete normal work. Running old and new access indefinitely preserves the original exposure.

Next Steps

Use this guidance as a starting point, assign clear ownership, and validate the approach against your organization’s systems, risks, and operating constraints.
