What is device management? A detailed guide

Every organization today runs on a mix of phones, tablets, laptops, and desktops spread across offices, homes, and coworking spaces. Keeping all of them secure, updated, and compliant is not something IT teams can do by hand anymore. That is the problem device management solves.

This guide covers what device management is, how it works, the related concepts you will run into (MDM, MAM, and EMM), and how a solution like ManageEngine Mobile Device Manager Plus fits into the picture.

What is the real cost of not managing your devices

The financial case for device management is not theoretical. The global average cost of a data breach was $4.44 million in 2025, and breaches in the United States averaged $10.22 million, the highest figure IBM has recorded for any country, according to IBM's Cost of a Data Breach Report 2025. Lost or stolen devices, weak passcodes, and outdated software remain common paths into a company network, and each unmanaged device adds to that exposure.

This is also why government security guidance treats device management as a core control, not an optional add-on. The U.S. National Institute of Standards and Technology (NIST) publishes dedicated guidance on this exact problem in NIST Special Publication 800-124, which recommends centralized device management and endpoint protection as standard practice for any organization letting employees access company data from mobile devices, company-owned or personal. The guidance exists because the risk is well documented: a single lost phone with access to email, customer records, or internal systems can turn into a costly breach in minutes.

What is device management?

Device management is the practice of enrolling, configuring, securing, monitoring, and managing an organization's devices, such as smartphones, tablets, laptops, desktops, and rugged handhelds, from a centralized console. It covers both company-owned devices and personal devices used for work under BYOD (bring-your-own-device) policies.

In practical terms, device management gives IT administrators a single place to:

• Enroll new devices, whether they arrive straight from the manufacturer or are already in an employee's hands
• Push security policies such as passcodes, encryption, and Wi-Fi or VPN settings
• Distribute, update, or remove business applications
• Monitor device health, location, and compliance status
• Remotely lock, wipe, or recover lost or stolen devices

Without device management, each of these tasks would have to be done manually, one device at a time. That approach does not scale once an organization has more than a handful of devices in circulation.

Why device management matters

As remote work, BYOD policies, and mobile-first workflows have become normal, device management has moved from a nice-to-have to a basic requirement.

Security risk. A device that is not encrypted, not passcode-protected, or running outdated software is an easy target. Corporate email, customer data, and internal apps are often just as reachable from a phone as from a laptop, so an unmanaged phone carries the same risk as an unmanaged laptop.

Compliance pressure. Regulations such as HIPAA (healthcare), GDPR (data privacy), PCI DSS (payments), and SOC 2 (service organizations) increasingly require proof of device-level controls, not just network security. Auditors want evidence that a lost device can be wiped, that data is encrypted, and that only approved apps can reach corporate resources.

Operational efficiency. Every minute an IT admin spends manually setting up a phone, chasing a lost device, or walking someone through a Wi-Fi setup is a minute not spent on higher-value work. Device management automates the repetitive parts of this job so IT teams can support far more devices without adding headcount at the same rate.

How device management works

Device management platforms, including Mobile Device Manager Plus, generally follow four stages.

1. Enrollment

Before a device can be managed, it has to be enrolled into the platform. Common methods include:

• Manual enrollment. An admin or user enters enrollment credentials directly on the device.
• Bulk enrollment. Multiple devices are enrolled at once using a CSV file, useful for large rollouts.
• Self-enrollment. Employees enroll their own devices, common in BYOD setups, typically authenticated with a one-time passcode or Active Directory credentials.
• Zero-touch enrollment. Devices are pre-configured so that the moment an employee turns one on, it enrolls itself, applies policy, and is ready to use, with no IT involvement needed.

2. Policy configuration

Once enrolled, a device receives configuration profiles that define how it behaves: passcode rules, Wi-Fi and VPN settings, encryption requirements, allowed or blocked apps, and restrictions on things like camera use or installing apps from unknown sources.

3. Monitoring and compliance reporting

The platform continuously checks in with enrolled devices, flagging ones that are jailbroken, rooted, running outdated software, or otherwise out of compliance. Non-compliant devices can be automatically restricted from corporate access or flagged for IT to review.

4. Remote management and response

This is where device management earns its keep. If a device is lost, stolen, or compromised, IT can lock it, check its last known location, or wipe corporate data, all without touching the hardware. Updates, app installs, and troubleshooting can also be pushed remotely.

Related concepts: MDM, MAM, and EMM

Device management is often used as a catch-all term, but three related terms come up constantly: MDM, MAM, and EMM. Here's the short version of each, followed by a detailed comparison table.

Mobile Device Management (MDM) is, by definition, scoped to mobile devices: enrollment, passcode enforcement, remote lock and wipe, and basic configuration. In practice, it has grown well beyond that. Most modern MDM platforms, including Mobile Device Manager Plus, have absorbed app-level controls that used to belong to a separate category called MAM, and many also manage laptops, desktops, and TVs alongside phones and tablets.

Mobile Application Management (MAM) narrows the focus to the app layer: managing and securing individual apps and the data inside them, without controlling the whole device. This was historically useful in BYOD situations where IT had no interest in, or right to, controlling the whole device but still needed to protect one app's data. Today, most of this capability sits inside MDM platforms rather than standing alone.

Enterprise Mobility Management (EMM) is genuinely broader than MDM, not just a different name for the same thing. It adds enterprise-wide app lifecycle management, content distribution, and identity or access management on top of what MDM covers. It's worth treating EMM as a distinct, wider layer rather than assuming MDM now does everything EMM does.

Since this article centers on Mobile Device Manager Plus, here is how it actually compares against MAM and EMM in practice:

As the table shows, Mobile Device Manager Plus covers full device management, MAM-style app control, and content distribution on its own. On identity, it connects to outside providers for authentication during enrollment, but it is not itself a full identity and access management platform with organization-wide SSO federation. That layer typically remains the job of a dedicated identity provider or a broader EMM tool.

What key features to look for in a device management platform

Not all device management tools are built the same way. Here is what separates a genuinely capable platform from a checklist of features, and how Mobile Device Manager Plus's feature set approaches each one.

• Zero-touch enrollment. Devices should arrive at employees pre-configured and secure from the moment they are powered on, with no manual setup step.
• OEMConfig support. Manufacturer-specific hardware settings, for rugged devices from Zebra or Honeywell or for enterprise Samsung devices, should not require custom code. Mobile Device Manager Plus supports OEMConfig for 30 or more device manufacturers directly from the console.
• App management. A private enterprise app catalog, silent app installs and updates, and the ability to block unauthorized or malicious apps are basic requirements for any serious deployment.
• Granular security policies. Passcode enforcement, full-device and external storage encryption, and URL filtering to block malicious content.
• Work profile containerization. For BYOD, the ability to separate work and personal data without a full device wipe when an employee leaves.
• Kiosk and dedicated device mode. For retail point-of-sale, warehouse scanners, or field service tools, devices should lock to a single app or a curated app set, with the ability to manage thousands of these dedicated devices centrally.
• Lost device protection. Real-time location tracking, remote lock and wipe through Lost Mode, and Enterprise Factory Reset Protection so a lost or offboarded device cannot simply be reset and reused by someone else.

Benefits of device management

• Stronger security posture. Centralized, consistent policy enforcement closes the gaps that come from devices being configured inconsistently or not at all.
• Reduced IT workload. Automated enrollment, patching, and app deployment mean IT can support significantly more devices without a proportional increase in headcount.
• Simplified compliance. Built-in reporting and audit trails make it far easier to prove device-level controls during a compliance review.
• Better support for remote and hybrid work. Devices can be managed, secured, and troubleshot from anywhere, without needing to be on the corporate network.
• Faster incident response. When a device is lost or an employee leaves, IT can act in minutes instead of days.
• Broad, unified coverage. Mobile Device Manager Plus manages phones, tablets, laptops, desktops, and TVs from one console, so IT is not juggling a separate tool for non-mobile endpoints.

What are the common challenges in device management

• Device and OS diversity. Android, iOS, Windows, macOS, and Chrome OS each behave differently, and different manufacturers add their own quirks on top. A platform with broad, native support for multiple manufacturers reduces this friction.
• Employee privacy in BYOD environments. Employees are understandably cautious about IT having visibility into their personal device. Clear policy communication and true containerization, not just a promise not to look, are essential for building trust.
• Scale. Managing a few dozen devices is very different from managing several thousand across multiple countries and device types. Enrollment automation and policy templates become critical at scale.
• Keeping pace with OS updates. Mobile operating systems update often, and new security features or restrictions can break existing configurations if a platform falls behind. Being an Android Enterprise Recommended partner, for example, gives a vendor early access to new Android capabilities before general release, which helps a platform stay ahead of these changes instead of reacting to them.

Device management best practices

• Write the policy before you buy the tool. Decide on passcode requirements, BYOD boundaries, and acceptable use before configuring anything.
• Use zero-touch or bulk enrollment wherever possible. Manual, one-by-one enrollment does not scale and introduces human error.
• Separate corporate-owned and BYOD policy tiers. Do not apply the same restrictions to a personal phone that you would apply to a company-issued one.
• Audit compliance regularly, not just at rollout. Devices drift out of compliance over time as OS versions change and apps are installed.
• Enable remote lock and wipe from day one. Do not wait until the first lost device to test whether this actually works.
• Look for genuine cross-endpoint support, not just phones and tablets. Laptops and desktops usually need managing too, and a single console beats stitching two tools together.
• Communicate privacy boundaries clearly to BYOD users. What IT can and cannot see or control matters for adoption and trust.
