Managed vs Unmanaged Devices: What's the Difference and Why Does It Matter?

Here's a question worth asking about every device in your business: is it managed or unmanaged?

If you're not sure what that means (or you suspect the answer might be "mostly unmanaged"), you're not alone. It's one of the most common gaps we find when we start working with UK SMEs, and it has a bigger impact on security and productivity than most people realise.

What is a managed device?

A managed device is one that your business has visibility and control over. That means:

• You can see it in your asset inventory

• It's running approved software and security settings

• It receives automatic updates and patches

• You can remotely lock, wipe, or access it if needed

• It's enrolled in your mobile device management (MDM) system

Managed devices behave predictably. If something goes wrong, you know about it - often before the user does.

What is an unmanaged device?

An unmanaged device is essentially flying blind. Your business may not even know it exists on your network. Common examples include:

• Personal laptops employees use for work

• Old company machines that were never properly enrolled

• Devices belonging to contractors or temporary workers

• Phones connected to company email without any oversight

In Q1 2025, 55% of UK SMEs discovered employees using applications outside of officially managed IT. Unmanaged devices make this problem significantly worse, and much harder to detect.

Why this gap matters

Every unmanaged device is a potential entry point for attackers. It's also a blind spot in your data compliance. You can't protect data you don't know exists, on a device you can't control.

Beyond security, unmanaged devices create operational headaches. Software updates get missed. People run incompatible tools. IT support becomes reactive and expensive because nobody has visibility of what's actually happening.

Getting from unmanaged to managed doesn't have to be painful

The shift to managed devices is usually simpler than businesses expect. At Equipped, we can audit your current device estate, identify the gaps, and get your fleet properly enrolled and managed, without disrupting your team's day.
