What is Device Management?

TL;DR

Device management is the practice of provisioning, configuring, securing, monitoring, and retiring the endpoints that employees use to access organizational resources. It encompasses both the software platforms (commonly called MDM, EMM, or UEM solutions) and the policies that govern how hardware moves through an organization.

At its core, device management answers a deceptively simple question: How do we give people the tools they need to work while keeping corporate data secure?

Hardware types under management typically include:

• Laptops and desktops (macOS, Windows, Chrome OS)
• Mobile devices (iOS, iPadOS, Android)
• Tablets and purpose-built devices (point-of-sale systems, kiosks, rugged field devices)
• Emerging endpoints (wearables, IoT sensors, smart displays, Apple Vision Pro)

What do MDM, EMM, and UEM stand for?

You'll encounter several acronyms in the device management space. Here's what they mean:

Today, UEM is the most accurate term for modern unified platforms like Iru, Microsoft Intune, and VMware Workspace ONE that manage all endpoint types. Apple-focused solutions like Jamf Pro are typically referred to as MDM or Apple device management platforms. In practice, all four acronyms remain in common use across the industry.

Context & Evolution

The old way: Sneakernet and golden images

A decade ago, device management meant something very different. IT teams maintained "golden images" , painstakingly configured master disk images that were cloned onto new machines.

Deploying a laptop required physical access: a technician would unbox the device, connect it to the network, image the drive, install applications manually, and configure settings before handing it to the end user. This process could take hours per device and days per batch.

Security updates followed a similar pattern. Patch Tuesday meant scheduling downtime, pushing updates through on-premises Windows Server Update Services (WSUS) or System Center Configuration Manager (SCCM), and hoping nothing broke.

Remote employees were particularly problematic. If a laptop wasn't connected to a corporate VPN, it might go weeks without critical patches.

Asset tracking lived in spreadsheets. When an employee left the company, IT relied on manual processes to recover hardware and wipe data. Devices fell through the cracks.

The new way: Cloud-first, zero-touch automation

Modern device management inverts this model entirely. Today's platforms operate from the cloud, pushing configurations over the air (OTA) to devices regardless of their physical location.

A laptop purchased from a vendor can ship directly to an employee's home, automatically enroll in the organization's management platform the moment it connects to the internet, and configure itself with the correct applications, settings, and security policies—all without IT touching the hardware.

Three forces drove this shift:

The rise of remote and hybrid work. Cloud-native management platforms can reach devices anywhere with an internet connection.

The proliferation of device types and operating systems. Organizations manage mixed fleets spanning Apple, Microsoft, Google, and Android ecosystems.

The escalating threat landscape. Ransomware, phishing, and nation-state attacks have made endpoint security a board-level concern.

The result is a fundamental shift from managing devices to managing the policies and configurations that devices consume.

Comparison at a Glance

Device management often gets conflated with adjacent disciplines. Understanding the boundaries helps clarify what falls under its umbrella—and what doesn't.

Device Management vs. Endpoint Security

In practice, the two disciplines overlap significantly. A well-managed device is inherently more secure: it receives patches promptly, runs only approved software, and enforces encryption. But they remain distinct functions with different operational concerns.

Device Management vs. IT Asset Management (ITAM)

Device management and IT asset management share a common subject—hardware—but approach it from different angles:

Mature organizations integrate both systems for complete visibility.

The Core Lifecycle

Device management operationalizes the hardware lifecycle—the journey every endpoint takes from procurement to retirement. The lifecycle comprises five stages:

Stage 1: Procurement and Planning

Before a device is purchased, organizations must decide what to buy, from whom, and under what terms:

Standardization decisions. Which device models and operating systems will be supported?

Vendor enrollment. Devices must be registered with programs like Apple Business Manager (ABM), Windows Autopilot, or Android Zero-Touch Enrollment.

Accessory and licensing planning. Peripherals and software licenses must be coordinated.

Stage 2: Provisioning and Enrollment

This is where modern device management diverges most dramatically from legacy approaches. In a zero-touch model:

1. The device ships directly to the end user
2. Upon first boot and internet connection, the device contacts the vendor's enrollment service
3. The enrollment service redirects the device to the organization's management platform
4. The management platform pushes an enrollment profile, installing a management agent and applying baseline configurations
5. Applications, settings, certificates, and policies flow to the device automatically
6. The end user experiences a setup wizard that takes minutes rather than hours

Stage 3: Configuration and Policy Enforcement

Once enrolled, devices enter ongoing management. The management platform continuously enforces:

Security policies. Passcode requirements, encryption mandates (FileVault, BitLocker), screen lock timeouts.

Application deployment. Required apps pushed silently; optional apps via self-service catalog.

OS and software updates. Patch policies define when updates install and how reboots are handled.

Compliance rules. Non-compliant devices can be flagged, alerted, or blocked from corporate resources.

Stage 4: Monitoring and Support

Device management platforms provide ongoing visibility into fleet health:

Inventory and reporting. Hardware specs, installed software, OS versions, encryption status, last check-in time.

Alerting. Notifications when devices fall out of compliance or fail to check in.

Remote actions. IT can remotely lock, wipe, restart, or trigger diagnostic commands without physical access.

Stage 5: Offboarding and Retirement

When an employee leaves or a device reaches end-of-life:

Data wipe. Full device wipe (corporate-owned) or selective wipe, and removing only managed apps and data.

Unenrollment. Device removed from management platform and vendor enrollment programs.

Asset disposition. Secure disposal or certified recycling ensures residual data doesn't leak.

Business & Security Case

Device management is no longer optional infrastructure—it's a business and security imperative.

Operational Efficiency

Security and Risk Mitigation

Patch compliance. Unpatched endpoints are the leading vector for ransomware. Device management ensures security updates reach devices within defined windows.

Data protection. Encryption enforcement, remote wipe, and conditional access prevent breaches when devices are lost or compromised.

Visibility and auditability. Compliance reporting demonstrates controlled endpoints to auditors, regulators, and cyber insurers.

Compliance and Governance

Regulatory frameworks—HIPAA, GDPR, SOC 2, PCI-DSS, CMMC—increasingly mandate endpoint controls. Device management provides the technical mechanisms (encryption, access controls, audit logs) and evidentiary artifacts (compliance reports, configuration baselines) that audits require.

Employee Experience

Modern device management isn't just about control—it's about enablement. Self-service app catalogs let employees install approved software without IT tickets. When done well, device management is invisible to end users. The device simply works, securely, from day one.

The Path Forward

Understanding device management is the first step. Here's how to move from concept to capability:

Getting Started Checklist

1. Inventory your current state. What devices exist? What operating systems? How are they managed today?
2. Define your requirements. What platforms must you support? What compliance frameworks apply?
3. Evaluate platforms. Options include Iru, Microsoft Intune, Jamf, VMware Workspace ONE, and others.
4. Pilot before rollout. Start with a subset of devices and users to validate workflows.
5. Integrate with identity. Connect to identity providers (Entra ID, Okta, Google Workspace) for conditional access and SSO.
