Microsoft Zero Trust Architecture Implementation
Microsoft Zero Trust Architecture Implementation assesses and implements an approved set of Microsoft identity, device, access, and risk controls using Microsoft Entra, Intune, Defender, and related services. Scope can include a maturity roadmap, Conditional Access, authentication strength, device compliance, risk-based access, privileged-access patterns, pilot rollout, exception handling, and an operating runbook. Pricing starts at $8,950 and depends on environment size, licensing, device state, applications, identity architecture, and remediation requirements.
What this engagement is
Zero Trust applies explicit verification, least privilege, and assumed-breach principles; it is not a single product or a promise to eliminate risk. IT Partner inventories access paths and dependencies, designs policies with emergency-access and service-account considerations, tests in report-only or limited pilot scope, and phases enforcement with user communications and rollback plans. Device enrollment, application modernization, broad identity cleanup, penetration testing, and continuous operations are included only when separately scoped.
Success criteria
What you receive
How the work unfolds
Confirm scope, stakeholders, target user/device populations, pilot groups, administrative access, change windows, communications approach, and success criteria for the Zero Trust rollout.
Assess Zero Trust maturity and produce a roadmap. Review current Entra ID, Conditional Access, authentication methods, privileged access, device-management posture, Defender signals, and existing access exceptions.
Design the Microsoft Zero Trust target state across identity, devices, and access, including Conditional Access policy structure, exclusions, emergency access approach, pilot scope, enforcement phases, and rollback considerations.
Design and roll out Conditional Access policies. Build or update policies for core scenarios such as MFA requirements, device compliance requirements, risky sign-ins, legacy authentication blocking where appropriate, administrative access, and application-specific controls.
Configure device-compliance and enrollment via Intune. Define practical compliance baselines, validate enrollment paths, align device groups, and confirm how compliant-device signals will be used in access decisions.
Configure identity-protection and risk-based policies. Configure risk-based controls where licensing and telemetry support them, and align response actions with the customer’s tolerance for user friction and helpdesk impact.
Implement least-privilege access patterns. Review high-risk standing access, administrative groups, and privileged access workflows, then recommend or configure practical least-privilege patterns within the agreed scope.
Validate policies in report-only mode before enforcement. Review policy insights, sign-in logs, impacted users, device compliance gaps, legacy authentication dependencies, and exception candidates before moving policies to enforcement.
Phase enforcement to avoid user disruption. Enforce policies by pilot group, department, risk tier, or application group as agreed, with monitoring and adjustment between rollout waves.
Provide the operations runbook, review ongoing monitoring and exception-management procedures, document final configurations and open recommendations, and complete administrator knowledge transfer.

Limitations & technical notes
Frequently asked questions
What is Microsoft Zero Trust Architecture Implementation?
Microsoft Zero Trust Architecture Implementation is a Microsoft-stack security service that replaces implicit network trust with continuous, explicit verification across identity, devices, and access. It uses Microsoft Entra ID, Microsoft Intune, and Microsoft Defender to implement controls aligned to Microsoft Zero Trust principles.
What is included in the Microsoft Zero Trust Architecture Implementation service?
The service includes a Zero Trust maturity assessment and roadmap, Conditional Access policy design and rollout, device compliance and enrollment via Intune, identity-protection and risk-based policies, least-privilege access patterns, and an operations runbook. Policies are validated in report-only mode before enforcement to reduce user disruption.
What Microsoft technologies does this Zero Trust service use?
This service is designed for organizations running the Microsoft security stack, specifically Microsoft Entra ID, Microsoft Intune, and Microsoft Defender. The implementation maps controls to Microsoft Zero Trust and focuses on identity, device health, risk, and access decisions.
How long does a Microsoft Zero Trust Architecture Implementation take?
The stated duration is 3 to 5 weeks, scoped by the customer environment. The exact schedule depends on the size and complexity of the tenant, device-management state, access requirements, and the level of validation needed before enforcement.
How much does Microsoft Zero Trust Architecture Implementation cost?
The service starts from $8,950, with final pricing scoped by environment. Pricing should be confirmed with IT Partner because tenant complexity, number of policies, device enrollment needs, and rollout requirements can affect the final scope.
What are the main deliverables of the engagement?
The deliverables are a Zero Trust roadmap, a designed and enforced Conditional Access policy set, device-compliance baselines, identity-protection configuration, and an operations runbook. These deliverables are intended to raise security posture without requiring a full platform replacement.
Does this service include a Zero Trust maturity assessment?
Yes, the engagement includes a Zero Trust maturity assessment and roadmap. The assessment establishes the current state and guides the phased implementation of Microsoft Zero Trust controls across identity, devices, and access.
How are Conditional Access policies handled during the project?
IT Partner designs and rolls out Conditional Access policies as part of the service. Policies are validated in report-only mode before enforcement, because this helps identify user impact and reduce disruption before controls are made active.
Will Conditional Access policies be enforced immediately?
No. Policies are designed with emergency-access and dependency considerations, evaluated in report-only or a limited pilot where supported, reviewed for impact, and enforced only after client authorization.
Does the service include Microsoft Intune device compliance?
Yes, the service includes device compliance and enrollment via Microsoft Intune, along with device-compliance baselines. The goal is to use device health as part of access verification rather than relying only on network location or user credentials.
Does this service configure identity protection and risk-based access?
Yes, identity-protection configuration and risk-based policies are included. These controls help access be evaluated per request based on identity signals, device health, and risk.
Does this Zero Trust implementation require re-platforming?
The service is designed to materially raise security posture without re-platforming. It implements Zero Trust controls across the Microsoft stack an organization already runs, rather than replacing the entire environment.
What business impact or downtime should we expect?
Most work does not require a planned platform outage, but access-policy and device-compliance changes can block or interrupt users whose devices, applications, identities, or authentication methods do not meet the new requirements. Pilot testing, communications, exceptions, and rollback reduce but do not eliminate that risk.
What does IT Partner do during the engagement?
IT Partner performs the Zero Trust maturity assessment and roadmap, designs and rolls out Conditional Access policies, configures Intune device compliance and enrollment, configures identity-protection and risk-based policies, implements least-privilege access patterns, validates policies in report-only mode, and phases enforcement. These responsibilities align to the stated service scope.
What are the client responsibilities for this service?
The source service description does not define specific client responsibilities. In practice, the customer should confirm with IT Partner what approvals, tenant access, administrative roles, stakeholder availability, and policy decisions will be required before the engagement starts.
What prerequisites are required before starting the implementation?
The published service content does not list required licensing, tenant access, admin roles, device-management state, or other prerequisites. These should be confirmed with IT Partner during scoping because the implementation depends on Microsoft Entra ID, Intune, and Defender capabilities.
What is not included in the Microsoft Zero Trust Architecture Implementation service?
The source service description does not specify out-of-scope items or additional-cost exclusions. Buyers should confirm whether items such as licensing purchases, non-Microsoft tooling, remediation of legacy applications, broad endpoint cleanup, or post-project managed operations are included before approving the scope.
What happens after the Zero Trust implementation is completed?
After completion, the customer receives an operations runbook along with the configured controls and roadmap deliverables. The runbook is intended to support ongoing operations, but the service description does not state that ongoing managed security operations are included.
How does this service improve least-privilege access?
The implementation includes least-privilege access patterns as part of the Zero Trust rollout. This helps reduce standing or excessive access by aligning permissions and access decisions with verified identity, device health, and risk.
Is this service suitable for organizations just starting with Zero Trust?
Yes, it can support organizations starting their Zero Trust journey because it includes a maturity assessment and roadmap before policy enforcement. It is also suitable for organizations already using Microsoft Entra ID, Intune, and Defender that want a phased, validated implementation of Zero Trust controls.
