The tool you already own

If you run a small business on Microsoft 365, there's a good chance you're already paying for a tool that could lock down every laptop and phone in your team - and you've never switched it on.

That tool is Microsoft Intune. It's Microsoft's cloud service for managing and securing the devices your staff use for work: laptops, desktops, phones and tablets. Instead of walking around and configuring each machine by hand, you set the rules once, in one place, and they apply to every device automatically.

Think of it as the control centre for your business devices. Who can access company data, on what, and under what security conditions - all decided by you, all enforced quietly in the background.

Why does a small business actually need it?

Most small businesses manage devices by trust and hope. Someone buys a laptop, logs into their email, and that's it. No encryption, no screen lock, no way to get the data back if it's lost.

Intune closes those gaps. Here's what it does for you day to day:

Enforces basic security automatically - device encryption, a PIN or password, and multi-factor authentication (MFA), applied to every device without relying on staff to set it up
Keeps devices patched and compliant - it checks that Windows and apps are up to date, and can block a device from company data if it falls behind
Remote-wipes a lost or stolen device - if a phone goes missing at the airport, you can erase the company data on it from your desk
Rolls out apps and settings centrally - install Microsoft 365, your line-of-business apps, wi-fi profiles and printers across the team in one action
Supports BYOD safely - staff can use their own phone for work email without you having control over their personal photos and messages
Onboards and offboards staff cleanly - a new starter's laptop sets itself up on first login; a leaver's access and data can be pulled back the same day

None of this needs a server in a cupboard. It all runs from the cloud.

You're probably already paying for it

Here's the part that surprises people. If your business is on Microsoft 365 Business Premium, Intune is included in the licence you already buy every month. Many businesses on Business Premium have it sitting there unused - paying for it and getting nothing from it.

It's a bit like buying a car with a built-in alarm and never turning it on. The protection is there. It just needs setting up properly for how your business works.

If you're on a cheaper plan like Business Standard, Intune isn't included - but the upgrade to Business Premium is often modest, and the security you get in return usually justifies it.

What does device management look like day to day?

Once it's running, most of Intune is invisible. That's the point - good security shouldn't get in the way of people doing their jobs.

In practice it looks like this:

A staff member unboxes a new laptop, logs in with their work account, and the machine configures itself - apps, settings, security, all applied before they touch anything
Their device quietly reports back that it's encrypted, patched and locked with a PIN - so you have proof it's compliant, not just a hope
If a device drops out of compliance (say, updates are switched off), it can lose access to company email and files until it's fixed
If someone leaves or loses a device, you handle it from your browser in a few clicks

You're not babysitting machines. You're setting sensible rules and letting the system hold the line.

What about the apps my team uses?

Application management is the other half of Intune, and it's where BYOD gets sorted.

Rather than controlling the whole personal phone, Intune can manage just the work apps on it - Outlook, Teams, SharePoint. You can require a PIN to open the work app, stop company data being copied into a personal app, and wipe only the work data if the person leaves.

Their personal side stays private and untouched. Your business data stays protected. Everyone wins, and you're not asking staff to hand over their own phone.

For company-owned devices, you can push approved apps out automatically and keep them updated, so nobody's running a three-year-old version of anything.

How does a small business get started without disruption?

The fear is always the same - "will this lock everyone out or break their machines mid-week?" Done properly, it won't.

A sensible rollout looks like this:

Start with a review - check what you're licensed for, what devices you have, and where the real gaps are
Set policies in report-only mode first - see who would fail the rules before anything is enforced, so there are no surprises
Roll out in small stages - one or two devices, confirm it's clean, then the rest
Enrol new devices as they come in - so onboarding gets easier from day one, not harder

The goal is that your team barely notices, other than new laptops setting themselves up faster and old security worries quietly going away.

The five-minute check

Log into your Microsoft 365 admin centre and look at your licence name. If it says Business Premium, you already own Intune - the only question is whether it's doing anything for you.

If you'd rather someone just told you, get in touch - a quick look at your tenant and I'll give you a straight answer on whether it's set up, half set up, or sitting idle.
