A Practical Zero Trust Roadmap Starts With Services

Zero Trust is difficult to sequence when the scope is an entire enterprise. A clearer starting point is a small set of important services and the identities, devices, workloads, data, and network paths that support them.

This service view makes trade-offs visible. Teams can identify where broad trust creates plausible attack paths and where an existing control already provides adequate assurance.

Conditional access depends on usable identity, device, and application signals. Least privilege depends on ownership and request workflows. Segmentation depends on understanding traffic and operational exceptions. Roadmaps should make those dependencies explicit.

Progress should be expressed through reduced standing privilege, stronger authentication coverage, fewer unmanaged devices, narrower service paths, and tested response. Maturity language can support planning, but funded initiatives need a defined control change and accountable owner.
