Intune Conditional Access: Using Intune and Entra ID Together

When people talk about Intune Conditional Access, they’re usually referring to the way Microsoft Intune and Microsoft Entra Conditional Access work together to control how users and devices connect to company resources. Conditional Access itself lives in Entra ID (formerly Azure AD), while Intune supplies the device compliance data those access decisions depend on.

Think of it as a security checkpoint. Before anyone can sign in to your apps or data, Conditional Access evaluates who they are, what device they’re using, and whether that device meets your organization’s security requirements. If everything checks out, access is granted. If not, it’s blocked or challenged with multi-factor authentication (MFA).

By combining identity and device context, Intune and Entra Conditional Access help you enforce Zero Trust principles, verifying every connection in real time while keeping users productive from anywhere.

Today’s users connect from everywhere, home offices, mobile networks, and personal devices. Traditional perimeter-based security can’t protect data in that kind of environment. Attackers target identities more than firewalls, and compromised credentials remain one of the most common causes of breaches.

What’s often called Intune Conditional Access is actually the integration of Microsoft Intune and Microsoft Entra Conditional Access, working together to secure how and when users access company resources. Intune provides device compliance information (confirming that a device meets encryption, patching, and protection standards) while Entra ID uses that information to make real-time access decisions.

This combined approach lets you:

• Block risky sign-ins automatically by evaluating device health, location, and sign-in context.
• Protect sensitive data by ensuring only secure, compliant devices can access Microsoft 365 and other connected apps.
• Support regulatory compliance with enforced encryption, MFA, and security baselines.
• Maintain productivity by allowing trusted users and healthy devices to connect without friction.

Together, Intune and Entra Conditional Access replace static network trust with dynamic, identity-driven protection, a core foundation of Microsoft’s Zero Trust model.

When a user tries to access a corporate resource such as Microsoft 365, Teams, or SharePoint, Conditional Access evaluates that request in real time. It checks who the user is, what device they’re using, and whether that device meets the organization’s compliance requirements. Intune plays a critical role here, supplying the device compliance data that helps Conditional Access determine whether to grant, block, or challenge the connection.

Here’s what happens during that process:

1. User Sign-In: The user initiates a sign-in to a protected app or service.
2. Policy Evaluation: Conditional Access evaluates assigned policies based on factors like user role, sign-in location, and session risk.
3. Device Compliance Check: Intune provides the device’s compliance status, confirming encryption, antivirus protection, and system health.
4. Decision and Enforcement: Based on the combined signals, the system decides whether to allow, block, or prompt for multi-factor authentication (MFA).

This approach replaces static network boundaries with dynamic, context-based access control. Instead of trusting every device inside the network, Conditional Access verifies user identity and device health for every sign-in.

These capabilities are available through Microsoft Entra ID and Intune, both included in Microsoft 365 Business Premium and higher-tier licenses, making it easy to implement adaptive security policies without additional tools or infrastructure.

With Intune Conditional Access in place, you can enforce access rules that adapt to your organization’s specific risk tolerance and operational needs. These policies work behind the scenes to secure sign-ins and data access without introducing unnecessary friction.

Require MFA for Admins and High-Privilege Roles

Administrators should always face the highest scrutiny. Conditional Access policies can require multi-factor authentication for every sign-in from privileged accounts, regardless of device or location. This is one of the most effective defenses against credential theft.

Block Access from Non-Compliant or Unmanaged Devices

By linking Conditional Access to Intune compliance, you can automatically block devices that don’t meet security standards, for example, missing patches, encryption, or antivirus protection. This ensures only trusted, healthy endpoints can connect to your environment.

Restrict Access to Corporate Data in Microsoft 365

You can configure policies so that only Intune-managed and compliant devices can open or download files from apps like SharePoint, OneDrive, or Teams. For personal or unmanaged devices, browser-only access can be enforced to prevent local data copies.

Use Location and IP Controls for Additional Safeguards

Conditional Access can block or challenge sign-ins from unfamiliar countries, regions, or IP ranges. Defining named locations helps differentiate between trusted and untrusted networks, reducing risk from geographically inconsistent activity.

Integrate Risk-Based Signals from Microsoft Defender for Endpoint

When Defender for Endpoint detects a compromised or high-risk device, that signal can automatically trigger a Conditional Access policy to block or restrict that device’s access until it’s remediated.

Enable BYOD Access with Limited Permissions

For bring-your-own-device (BYOD) scenarios, you can allow browser-based access to Microsoft 365 while restricting downloads or local data storage. This approach gives flexibility to remote or contractor users without exposing sensitive data.

Each of these scenarios strengthens security by applying adaptive controls based on user, device, and session context. Over time, these policies create a consistent enforcement layer that aligns directly with your Zero Trust goals, verifying each access request without compromising productivity.

Deploying Conditional Access using Intune requires careful planning and testing. Conditional Access policies are configured in Microsoft Entra ID, while Intune provides the device compliance data those policies rely on. The objective is to apply security controls that protect access to company resources without disrupting how users work. The steps below outline how to roll out Conditional Access in a structured, low-risk way.

1. Identify Priority Users and Applications

Start by defining who and what needs protection first. Begin with high-value accounts such as administrators, executives, or teams with access to sensitive data. Focus on core cloud apps like Microsoft 365, Exchange Online, or SharePoint, expanding coverage once initial testing succeeds.

2. Establish Compliance Baselines in Intune

Before enforcing any access controls, ensure Intune compliance policies are defined and deployed. This typically includes encryption, antivirus, and OS patching requirements. Conditional Access will rely on this compliance data to determine which devices are trusted.

3. Configure Conditional Access Policies in Entra ID

Within Microsoft Entra ID, create Conditional Access policies that evaluate the factors that matter most, user identity, device compliance, location, and session risk. Combine these signals to determine whether to grant, block, or challenge sign-ins with MFA.

4. Start in Report-Only Mode

Enable Report-only mode to observe how your policies behave without enforcing them. This step helps you understand the real impact on users, devices, and apps — and provides clear data on which configurations need adjustment before going live.

5. Review Results and Adjust Conditions

Monitor the Entra ID sign-in logs and the Conditional Access Insights and Reporting workbook. Identify any unexpected blocks or gaps and refine your conditions, exclusions, or MFA prompts accordingly.

6. Move to Enforcement Gradually

Once testing confirms that your policies are behaving as intended, move from report-only to enforcement in stages. Start with one group or application at a time and monitor user feedback closely during rollout.

7. Maintain Continuous Review

After deployment, review your policies regularly to ensure they align with current security posture and business requirements. Device health, compliance standards, and threat levels evolve, your Conditional Access configuration should evolve with them.

A measured rollout like this minimizes disruption while ensuring your access controls align with your Zero Trust strategy. By combining Entra Conditional Access with Intune compliance data, you can enforce consistent, adaptive security policies across every user and device in your environment.

When Conditional Access policies are used with Intune, they give you the flexibility to enforce identity and device-based controls in a single framework. The goal is to design rules that are strong enough to protect your data but balanced enough to keep users productive. These best practices help maintain that equilibrium over time.

Start with Report-Only Mode

Always test before enforcing. Report-only mode lets you preview how a policy will behave and which users or devices would be affected. Once you’re confident in the results, move the policy into enforcement.

Combine MFA with Device Compliance

Multi-factor authentication protects against credential theft, but it doesn’t verify device health. Pair MFA with Intune compliance data to ensure users are signing in from secure, trusted devices.

Segment Policies by Role or Group

Avoid blanket “all users” policies. Apply stricter controls for administrators and service accounts, and more flexible conditions for standard users. This improves usability while maintaining protection where it matters most.

Use Named Locations for Known Networks

If your users regularly work from known IP ranges, such as office locations or corporate VPNs, mark them as trusted. This reduces unnecessary MFA prompts and helps identify unusual activity from unknown regions.

Exclude Break-Glass Accounts

Always maintain at least one emergency admin account exempt from Conditional Access. It’s your recovery option if a policy is misconfigured or access is unintentionally blocked.

Audit and Simplify Regularly

Over time, overlapping policies can cause conflicts and confusion. Schedule quarterly reviews to remove duplicates, rename policies clearly, and confirm they still align with your current security posture.

Monitor User Impact and Adjust Gradually

Review Conditional Access insights and sign-in logs to see how users experience your policies. Adjust thresholds or MFA frequency based on data rather than assumptions. A well-tuned policy is one users barely notice.

To get the most value from Conditional Access with Intune, you’ll need an ongoing process of review and refinement. As devices, roles, and risks change, your access controls should evolve to stay aligned with your security posture.

Review Conditional Access Insights

The Conditional Access Insights and Reporting workbook in Microsoft Entra provides detailed visibility into how policies perform, showing which users are challenged, blocked, or bypassing conditions. Reviewing this regularly helps you identify both risk patterns and user friction points.

Analyze Sign-In Logs

Use the Entra sign-in logs to trace policy outcomes and troubleshoot unexpected behavior. Filtering by policy result (success, failure, report-only) can reveal which rules are too restrictive or not restrictive enough.

Correlate with Threat Signals

Look at data from Defender for Endpoint or Entra ID Protection to see how real-world risk signals align with your access policies. While these aren’t direct integrations, reviewing them together helps you fine-tune conditions based on how threats actually surface in your environment.

Adjust Policies with Evidence, Not Assumptions

If MFA prompts are happening too frequently, or users in specific regions experience delays, analyze the logs before changing policy settings. Adjusting based on data ensures you maintain protection without weakening security.

Reassess Quarterly

Schedule quarterly or semiannual reviews to confirm your Conditional Access setup still matches your Zero Trust and compliance goals. Over time, you’ll establish a rhythm of continuous improvement, where each adjustment builds on measured insight, not reaction.

What many refer to as Intune Conditional Access is really the combined power of Microsoft Entra Conditional Access and Intune compliance policies working together. Entra Conditional Access decides who can access your resources and under what conditions, while Intune provides the real-time device compliance data that determines whether that access should be allowed.

When configured correctly, this combination forms one of the most effective layers in Microsoft’s Zero Trust security model, verifying user identity, device health, and location before any connection is made. It helps you prevent unauthorized access without interrupting how your teams work.

What is Intune Conditional Access?

Intune Conditional Access isn’t a separate Microsoft product, it’s the term often used to describe how Microsoft Entra Conditional Access and Intune work together. Entra Conditional Access decides whether a user can access a resource, while Intune provides the device compliance information that influences that decision. Together, they ensure that only trusted users on secure, compliant devices can connect to your organization’s data.

How does Conditional Access work with Intune?

Conditional Access policies use Intune’s compliance data to make real-time access decisions. When a user signs in, Entra ID checks their identity and risk level, and Intune confirms whether the device meets your compliance standards (like encryption and antivirus). Access is granted, blocked, or challenged based on these combined signals.

Can Conditional Access block unmanaged devices?

Yes. By requiring device compliance as a condition for access, you can automatically block unmanaged or non-compliant devices from connecting. This is one of the simplest and most effective ways to prevent unauthorized access.

Does Conditional Access work on macOS, iOS, and Android?

It does. Conditional Access applies consistently across operating systems through Intune’s device management framework. Each platform reports its compliance status to Intune, allowing policies to enforce access based on that data.

What licenses are required to use Conditional Access with Intune?

You’ll need Microsoft Entra ID P1 or P2 licensing, which are included in Microsoft 365 Business Premium, E3, and E5. This covers both the Conditional Access policies in Entra ID and the Intune compliance features that feed into them.

How can I test Conditional Access before enforcing it?

Enable Report-only mode to preview how a policy behaves without impacting users. This mode logs policy results,   allowing you to fine-tune your setup and verify outcomes before turning enforcement on in production.
