Microsoft Intune Mobile Device Management: Getting Started

Introduction

Intune mobile device management gives small and mid-sized businesses a practical, cloud-based way to secure and control every smartphone, tablet, and laptop their employees use for work. As remote work and bring-your-own-device policies become the norm rather than the exception, keeping company data safe across a growing fleet of personal and corporate devices is no longer optional. Microsoft Intune sits inside the Microsoft 365 ecosystem, which means many SMBs already have access to it without realizing it. This guide walks you through what the platform does, how it works under the hood, and the concrete steps you need to take to get up and running.

What Microsoft Intune Actually Does for Your Business

Microsoft Intune is a cloud-based endpoint management solution that lets IT administrators enroll devices, push configuration profiles, enforce security policies, and deploy or remove applications — all from a single web-based console. It supports Windows, macOS, iOS, iPadOS, and Android, so whether your team is using company-issued Surface laptops or personal iPhones to check work email, Intune can apply consistent governance across all of them. The service is part of Microsoft Endpoint Manager, which also includes Configuration Manager for organizations that still manage on-premises servers and workstations. For SMBs that live almost entirely in the cloud, the Intune-only path is usually the cleanest and most cost-effective approach.

Beyond basic device enrollment, Intune handles conditional access in partnership with Azure Active Directory (now called Microsoft Entra ID). This means you can write a policy that says, for example, only devices that are enrolled, compliant, and running an approved OS version can access Microsoft Teams or SharePoint. If a device falls out of compliance — perhaps because an employee skipped a critical security update — access is automatically blocked until the issue is resolved. For a small business without a dedicated security team, that kind of automated enforcement is enormously valuable because it removes the dependency on manual audits and individual employee judgment.

How Intune Manages Devices Behind the Scenes

When a device enrolls in Intune, a lightweight management profile or agent is installed that creates a secure channel between the device and the Intune service in Microsoft's cloud. Through that channel, Intune can read device health signals — OS version, encryption status, jailbreak detection, installed applications — and compare them against the compliance policies you have defined. If everything checks out, the device receives a compliant status and conditional access policies allow it through. Configuration profiles are then pushed down to the device automatically, setting things like Wi-Fi credentials, VPN configurations, email account settings, and password requirements without the employee having to configure anything manually.

Intune supports two fundamentally different management models that are worth understanding before you start enrolling devices. Mobile Device Management, or MDM, gives Intune full visibility and control over an entire device — ideal for corporate-owned hardware. Mobile Application Management, or MAM, focuses only on the work apps and the data inside them, leaving personal apps and content completely untouched — ideal for employee-owned devices where privacy is a concern. You can also combine both approaches, enrolling a device in MDM while also applying MAM policies to specific apps, which gives you flexibility as your device mix evolves. Choosing the right model upfront saves a significant amount of rework later.

Step-by-Step Guide

1. Verify Your Licensing: Before touching any settings, confirm that your Microsoft 365 subscription includes Intune — it is included in Microsoft 365 Business Premium, EMS E3, and several other plans. Log into the Microsoft 365 admin center and navigate to Billing, then Licenses, to see what is assigned to your tenant.
2. Set Up Your Azure AD / Microsoft Entra ID Tenant: Intune relies on Azure Active Directory for user identities, so make sure your users are synced or created in Entra ID before you begin enrollment. If you are still running on-premises Active Directory, configure Azure AD Connect to sync your existing accounts to the cloud so Intune can target the right users and groups.
3. Configure the MDM Authority: Inside the Microsoft Intune admin center at intune.microsoft.com, set Microsoft Intune as your MDM authority — this is a one-time configuration that tells the tenant which management platform is in charge. Navigate to Tenant Administration, then Tenant Status, and confirm the MDM authority is set correctly before proceeding.
4. Create Compliance Policies: Go to Devices, then Compliance Policies, and build policies for each platform you support — Windows, iOS, and Android each have their own settings. Define your minimum requirements, such as OS version thresholds, required encryption, screen lock settings, and whether jailbroken or rooted devices should be automatically marked non-compliant.
5. Build Configuration Profiles: Configuration profiles push settings to devices automatically after enrollment, so create profiles for each platform that cover Wi-Fi, VPN, email, and any security baselines you want enforced. Microsoft provides pre-built security baseline templates for Windows that reflect current best-practice recommendations, which is a good starting point for most SMBs.
6. Set Up Conditional Access Policies: In the Microsoft Entra ID admin center, create conditional access policies that require device compliance as a condition for accessing cloud apps like Exchange Online, SharePoint, and Teams. Link these policies to the user groups you plan to enroll first so you can test the experience before rolling out to the entire organization.
7. Enroll Your First Devices: For corporate Windows devices, use Windows Autopilot to automate enrollment during initial setup; for iOS and Android, send users to the Company Portal app and walk them through the enrollment steps. Start with a pilot group of five to ten users, verify that compliance status, profiles, and conditional access all behave as expected, then roll out to the rest of the organization in waves.

Intune vs. Other Endpoint Management Platforms

Best Practices

• Start With a Pilot Group: Always test new compliance and configuration policies on a small, representative group of devices before deploying organization-wide to catch unexpected conflicts or user experience issues early.
• Use Security Baselines for Windows: Microsoft's built-in security baseline templates encode hundreds of recommended settings and save significant configuration time compared to building policies from scratch.
• Separate Corporate and Personal Device Policies: Create distinct device groups and apply MDM policies to corporate hardware while using MAM-only policies for personal devices to respect employee privacy and reduce enrollment friction.
• Enable Self-Service Through the Company Portal: Train employees to use the Intune Company Portal app to install approved applications and check their own compliance status, which reduces helpdesk tickets and empowers users.
• Review Compliance Reports Weekly: Schedule a standing review of the Intune compliance dashboard to catch devices that have drifted out of compliance before they become a security incident rather than after.

Frequently Asked Questions

Does Intune Work With Personal Devices That Employees Own?

Yes, Intune supports a bring-your-own-device scenario through its Mobile Application Management capabilities, which allow you to manage and protect work data inside specific apps without touching personal photos, messages, or other private content. Employees enroll through the Company Portal app and only the work-related apps and their associated data fall under IT control. This approach typically requires less employee buy-in than full MDM enrollment because workers can see clearly that their personal content is not being monitored. Many SMBs use MAM-without-enrollment for personal devices so that no management profile is installed on the device at all.

What Happens to Company Data When an Employee Leaves?

Intune gives administrators a selective wipe capability that removes only corporate apps, email accounts, configuration profiles, and associated data from a device while leaving personal content completely intact. For corporate-owned devices, a full factory reset can be triggered remotely from the Intune admin center, wiping everything and returning the device to a clean state. These actions can be initiated within minutes of an employee's departure, which significantly reduces the window of exposure compared to manual offboarding processes. Combining Intune wipe capabilities with prompt account deactivation in Entra ID provides a solid offboarding workflow for most SMBs.

How Much Does Microsoft Intune Cost for a Small Business?

For many SMBs, Intune is already included in their existing Microsoft 365 subscription at no additional cost — Microsoft 365 Business Premium, for example, bundles Intune alongside Defender for Business and Azure AD Premium P1. If your current plan does not include Intune, it is also available as a standalone add-on or as part of the Enterprise Mobility and Security E3 bundle. It is worth auditing your current licensing before purchasing anything new because a surprising number of small businesses are already paying for Intune without using it. An Always Beyond licensing review can quickly identify whether you are already covered.

How Long Does It Take to Deploy Intune Across a Small Business?

A basic Intune deployment covering compliance policies, configuration profiles, and conditional access for a company of 25 to 50 users can typically be completed in two to four weeks when planned carefully. The timeline depends heavily on the diversity of your device fleet — a single-platform environment with only Windows laptops moves faster than one that includes Windows, macOS, iOS, and Android. User communication and training add time but are worth the investment because enrollment problems are almost always caused by user confusion rather than technical failures. Working with a managed IT partner like Always Beyond can compress that timeline significantly because the foundational decisions have already been made many times before.

Can Intune Replace Our Existing Antivirus or Security Software?

Intune is a management and policy enforcement platform rather than a security product in the traditional sense, so it does not replace endpoint protection software on its own. However, it integrates natively with Microsoft Defender for Endpoint, which provides antivirus, endpoint detection and response, and threat intelligence capabilities across Windows, macOS, iOS, and Android. When Intune and Defender for Endpoint are connected, device risk signals from Defender feed directly into Intune compliance policies, so a device that Defender flags as compromised can automatically lose access to corporate resources. For most SMBs running Microsoft 365 Business Premium, the combination of Intune and the included Defender for Business provides a robust, fully integrated security stack without needing additional third-party tools.

Getting Intune mobile device management configured correctly from the start saves countless hours of troubleshooting and dramatically reduces your exposure to data breaches caused by unmanaged devices. The team at Always Beyond has helped dozens of SMBs plan, deploy, and maintain Intune environments that fit their specific device mix, compliance requirements, and budget — so you do not have to figure it out alone.
