Microsoft Intune Explained for Small-Business Leaders

Microsoft Intune is Microsoft's tool for managing the laptops, desktops, phones and tablets that access company data. It can set security rules on company devices, install apps, check that devices meet your standards, and erase a lost device remotely. It can also protect company email and files on an employee's personal phone without taking control of the whole phone. Intune Plan 1 is included in Microsoft 365 Business Premium.

Why it matters in business terms

Your firm's data no longer lives only on an office server. It sits in email, OneDrive and Teams on every device staff use, including phones on kitchen counters and laptops in airport lounges. Without device management, you have little say over whether those devices are encrypted, updated or protected by a PIN, and limited options when one goes missing.

Intune gives you that say. It also produces evidence: a list of devices, whether each meets your rules, and when it last checked in. That evidence is often what clients, auditors and cyber insurance applications ask about.

Company-managed devices

For devices the firm owns, Microsoft recommends full management, which it calls mobile device management (MDM). Once a device is enrolled, Intune can manage nearly every aspect of it.

Personal devices and app protection policies

Many staff do not want their employer managing their personal phone, and that is reasonable. Intune's app protection policies, which Microsoft calls mobile application management (MAM), protect company data inside specific apps instead of managing the device.

With app protection, company data in Microsoft apps such as Outlook, Teams and OneDrive can be required to sit behind a PIN, blocked from being copied into personal apps, and encrypted. If the person leaves or loses the phone, you can remove only the company data from those apps. Their photos, texts and personal apps are untouched.

There are trade-offs. Without enrollment, you cannot push apps to the device or wipe it entirely, and the user installs apps from the app store. For most professional firms, app protection on personal phones and full management on company laptops is a sensible split.

Windows Autopilot for new laptops

Windows Autopilot changes how new Windows laptops are set up. Instead of someone building each machine by hand, the laptop is registered to your organization, often by the reseller at purchase. When the new employee turns it on and signs in with their work account, it joins your Microsoft Entra ID directory, enrolls in Intune and pulls down its settings and apps.

For a remote-first firm, that means a laptop can ship straight from the supplier to a new hire's home. Autopilot's automatic Intune enrollment requires Microsoft Entra ID P1 or P2 for configuration, which Business Premium includes.

How Intune pairs with Conditional Access

Intune and sign-in rules (Conditional Access) work as a pair. Intune decides whether a device is compliant and reports that status to Microsoft Entra ID. A Conditional Access policy can then require a compliant device before granting access to email, SharePoint or a sensitive line-of-business app.

For example, a policy might say: partners can open the document management system only from a compliant company laptop, while everyone can reach Outlook on a personal phone as long as app protection is applied. Microsoft notes that a compliant-device policy will not work as intended until compliance policies exist in Intune, so the device side has to come first.

Licensing, as of this writing

When a small firm actually needs it

Take a 12-person accounting firm where everyone has a company laptop and most staff read email on personal phones. Intune earns its place if any of these are true:

If you have five people, all on company laptops that rarely change, and no one uses phones for work, Intune may be lower priority than MFA, backup and endpoint protection. It is a tool to fit to the problem, not a box to tick.
