Microsoft Intune Guide for SMBs

Microsoft Intune is cloud endpoint management for the devices your people actually use—Windows laptops, macOS, iOS, and Android—tied tightly to Microsoft Entra ID and Microsoft 365. For many SMBs, it replaces ad-hoc imaging, spreadsheet inventories, and “we think BitLocker is on.”

This guide is for owners and IT operators who want managed, healthier devices without building a full enterprise desktop engineering team. It pairs with our Microsoft 365 Security Guide and Identity & Zero Trust guide.

What Intune is (and is not)

Intune is Microsoft’s unified endpoint management (UEM) service. It can:

• Enroll and inventory devices
• Push configuration profiles (Wi-Fi, VPN, encryption, update policies)
• Measure compliance (e.g., encryption on, OS version current)
• Deploy apps and manage updates at a basic level
• Protect corporate data on personal devices via app protection policies

It is not a full replacement for every on-prem Group Policy scenario overnight, and it is not magic without identity hygiene. Glossary: Intune, MDM, MAM.

Why SMBs adopt Intune

• Remote and hybrid work made “touch every laptop” impossible
• Insurance and customer questionnaires ask about device encryption and management
• Conditional Access can require compliant devices for sensitive apps
• Consistent baselines beat hero technicians

Enrollment models (keep it simple)

Common paths:

• Corporate Windows devices — Autopilot + Entra join / hybrid join patterns
• macOS — Company Portal enrollment with clear ownership labels
• Phones — full MDM for company phones; app protection for BYOD

Pick a primary model per platform and document exceptions. Article: Intune device enrollment.

Windows Autopilot

Windows Autopilot lets new (or reset) PCs configure themselves with cloud policies when a user signs in—reducing imaging USB rituals.

Autopilot works best when:

• Hardware hashes are registered cleanly
• Deployment profiles and ESP expectations are realistic
• Apps are sequenced so first login is not a 3-hour surprise

Configuration profiles and compliance

Two related ideas:

• Configuration — push the settings you want (BitLocker, firewall, update rings)
• Compliance — measure whether the device meets your bar

Compliance becomes powerful when Conditional Access requires a compliant device for SharePoint, Exchange, or line-of-business apps. Article: Intune compliance policies.

App management

Start with the apps everyone needs: Company Portal, Office, browser, VPN/security agents. Avoid boiling the ocean on day one packaging every niche utility.

BYOD and app protection

Not every phone should be fully managed. Mobile Application Management (MAM) / app protection policies can protect corporate mail and files on personal devices without taking over the whole phone.

Security stack pairing

Intune manages posture. You still want:

• Strong identity (MFA, Conditional Access)
• EDR on endpoints
• Sensible backup for cloud and critical local data

See EDR and SMB Cybersecurity Guide.

Common mistakes

1. Enrolling devices with no baseline policies
2. Autopilot demoed once, never operationalized for new hires
3. Compliance policies so strict nobody can work—then exceptions everywhere
4. BYOD full MDM when app protection would have been enough
5. Ignoring macOS and mobile while only hardening Windows

A practical rollout path

1. Confirm licensing and admin roles
2. Define corporate vs personal device strategy
3. Pilot Windows baseline (encryption, updates, Company Portal)
4. Add compliance + Conditional Access for one sensitive app
5. Pilot Autopilot for new devices
6. Expand apps and macOS/mobile policies
7. Document support runbooks for enrollment failures
