The Definitive Guide to Managing +100 Devices in Your Company Without Losing Control

Once a company grows past 100 endpoints, manual device management stops being viable. Without an up-to-date inventory and a centralised system, problems build up before anyone notices. There comes a point where the spreadsheet and the emails to the IT department simply stop working. Beyond a certain number of machines, informal administration creates more problems than it solves: outdated equipment, expired licences, and a record that reflects what the company looked like two years ago. It is not just a question of organisation — it is a question of security and cost. And it has a solution, even if it requires changing the way things are done.

Why the Inventory Is the Starting Point

You cannot manage what you do not know you have. Before anything else, it is essential to have a complete, up-to-date inventory: which devices exist, who uses them, what operating system they are running, what software is installed, and when they were last updated.

In many companies that information does not exist with any accuracy, or it does, but scattered across several tools that do not talk to each other. The first real step toward control is bringing all of that data into a single place.

What Changes When Device Management Is Done Centrally

Centralising device management does not mean adding bureaucracy. It means that when something goes wrong, you know exactly where the problem is and who needs to fix it. It means security updates roll out across the entire fleet without relying on each user to accept them. And it means that when someone leaves the company, you can revoke access and recover the device without depending on anyone's memory.

The most concrete benefits of working with a centralised platform are these:

  1. Full visibility over the device fleet

    In real time, with no need for periodic manual audits.

  2. Remote deployment of updates

    Applications and security policies pushed to all devices at once.

  3. Automatic detection

    Of devices that do not meet the company's minimum security requirements.

  4. Lifecycle management

    From device onboarding through to retirement, with the inventory updated at every step.

  5. Faster incident response

    Because the technician already knows what is on the device before opening a ticket.

  6. Software licence control

    Avoid paying for tools nobody uses, or unknowingly using tools without a valid licence.

The Tools Are Not the Problem, the Process Is

There is excellent software available for device management at scale. But technology alone solves nothing without a process behind it: what happens when a new device arrives, who approves what software gets installed, how a lost or stolen device is handled, how often the inventory gets reviewed.

Those are the questions that separate a company that truly controls its infrastructure from one that simply has tools installed.

Signs That Your Device Management Needs to Change

It is not always easy to tell when the current system has stopped working, because the symptoms tend to appear gradually. There are clear signs, though: the IT department spends more time firefighting than on planned tasks, there are devices in active use with no updated inventory entry, and security updates depend on each user installing them manually. Add to that not knowing how many active licences the company holds right now, or onboarding a new employee taking longer than it should because the process has never been standardised.

If any of this sounds familiar, the problem is not the size of your fleet, it is the method. And the sooner it is addressed, the less it costs to fix.
