What is an MDM system?

As remote work has become the new normal, mobile devices – smartphones, tablets, and laptops – have become essential business assets. With this dependency on mobile devices comes the need for effective device management and protection of sensitive data.

This is where a Mobile Device Management (MDM) system comes in. It allows you to remotely enroll, configure, secure, and manage IT devices across your company – instead of handling each one manually. This streamlines operations and strengthens security in our increasingly mobile work environment.

And since NIS2 came into force in December 2025, endpoint security is no longer optional for many SMBs in Germany – it's a legal obligation.

3 benefits of an MDM system

1. Time and resource savings in IT administration

Time-consuming processes like setting up new devices are automated through zero-touch deployment, enabling remote configuration with just a few clicks. This saves hours – or even days – of individual setup effort.

Software updates and applications can be rolled out to all devices simultaneously, instead of updating each one manually. For a company with 30 employees, this can easily mean 10+ hours per update cycle reduced to minutes.

What this means in practice: New employees receive a pre-configured device. They turn it on, log in – and everything is already installed, configured, and secured. No IT person needs to be physically present.

2. Simplified device management and optimised IT asset usage

Keeping track of the range of devices, applications, tools, and operating systems in a business can quickly become overwhelming. With an MDM system, you get a complete overview of all desktops, laptops, tablets, and mobile devices.

At a glance, you can see: which devices are active, what software is installed, which devices have pending updates, and which device is assigned to whom. This visibility isn't just operationally valuable – it's a prerequisite for compliance audits under GDPR and NIS2.

What this means in practice: When an employee leaves, you immediately see which devices and accounts were assigned to them – and can revoke everything in one step.

3. Strong security measures and data protection

Maintaining security across a large number of devices is one of the biggest challenges for SMBs. With MDM, you can centrally enforce company-wide security standards: set password policies, restrict app installations, enable disk encryption, and automatically roll out OS updates.

Crucially: if a device is lost or stolen, you can immediately lock or wipe it remotely – preventing sensitive company data from falling into the wrong hands. 46% of devices used for work purposes are insufficiently secured. MDM closes this gap systematically.

What this means in practice: You don't have to rely on employees installing updates or encrypting their devices. MDM enforces these standards automatically, on every device.

The limitations of traditional MDM systems

Traditional MDM systems aren't a universal solution. Two limitations are particularly relevant for SMBs:

Technical expertise required: Effectively managing an MDM system requires solid knowledge of device configuration, security protocols, and software deployment. Without sufficient expertise, misconfigurations can quickly create new security gaps – the opposite of the intended effect.

Platform specificity and costs: Many MDM solutions are platform-specific – a solution for Apple devices doesn't automatically cover Windows devices and vice versa. Add to this licence costs that can grow significantly as the number of devices increases.

Conclusion

An MDM system isn't just a convenience – it's a critical security tool for any business in the digital age. It simplifies device management, creates visibility, and reduces security risks – especially for SMBs without a dedicated IT team.

For companies that lack the technical expertise or time to build and operate an MDM system themselves, deeploi offers an all-in-one solution: MDM with professional management, licensing, and IT support in a single platform.

FAQ

What is MDM and what is it used for?

‍MDM stands for Mobile Device Management – a system for centrally managing all company devices. It allows you to remotely configure devices, deploy software, enforce security policies, and lock or wipe devices if they're lost or stolen. It covers laptops, smartphones, tablets, and any other endpoints that access company data.

Does my SMB really need an MDM system?

‍From around 10 devices, or as soon as employees work remotely, yes. Without MDM you don't know which devices are running which software version, whether disk encryption is active, or who still has access to company data after an employee leaves. These aren't theoretical risks – they're the most common entry points for attacks on SMBs.

What's the difference between MDM and UEM?

‍MDM focuses on mobile devices and laptops. UEM (Unified Endpoint Management) goes further, managing all endpoints – including desktop PCs, IoT devices, and virtual machines – in a single platform. For most SMBs, MDM is sufficient; UEM makes more sense when you have a more heterogeneous device and systems landscape.

Can MDM be used on personal devices (BYOD)?

‍Yes – most MDM solutions offer a BYOD mode that only manages the business portion of the device, without accessing personal data. This protects company data while respecting employee privacy. Importantly, employees should be transparently informed about the scope of MDM management on their personal devices.

Is MDM sufficient for NIS2 compliance?

‍MDM alone doesn't fully satisfy NIS2 – but it's one of the core measures. NIS2 Article 21 requires endpoint security, patch management, and access controls, among other things. MDM provides the technical foundation for all three. For full NIS2 compliance, you additionally need BSI registration, incident response processes, and management accountability.

How much does an MDM system cost?

‍Traditional MDM licences cost between €3 and €15 per device per month depending on the provider and feature set. Setup and operational costs come on top if you manage the system yourself. A managed IT service like deeploi bundles MDM, support, and device management in a flat-rate model – without hidden licence costs.
