Microsoft Intune for Small Business: Is It Worth Setting Up?

Most small businesses manage their laptops the same way. Someone buys a machine, sets it up by hand, installs whatever the new starter asks for, and hands it over. Every device ends up slightly different. Nobody is quite sure which ones are encrypted, which are up to date, or who still has access to what.

That works until a laptop gets left on a train, or someone leaves on bad terms with the client list synced to their personal phone. Then the question becomes very specific, very quickly: can we lock that down, right now?

Microsoft Intune is how most businesses on Microsoft 365 answer yes. Here is what it actually does, whether you are already paying for it, and when it is worth the effort of setting up properly.

You may already be paying for it

This is the part that surprises people.

Business Premium is capped at 300 users, which covers almost every small business, and it bundles the three things that do the heavy lifting together: Intune to manage the devices, Conditional Access to decide who gets in, and Defender for Business to watch for threats.

If you are on Business Premium and nobody has configured Intune, you are paying for device management and not using it. That is common. It is also the cheapest security improvement available to you, because the licence cost is already sunk.

If you are on Business Standard, the step up to Premium is usually the most sensible move before buying any separate security product. Check current pricing with your provider, as Microsoft adjusts it periodically.

What Intune actually controls

Strip away the terminology and Intune does five jobs.

1. Setting devices up the same way, every time

With Windows Autopilot, a new laptop can be shipped straight to a staff member. They unbox it, connect to wifi, sign in with their work account, and the device configures itself: company settings, security policies, and the apps they need. Nobody from IT has to touch it.

On the Apple side, Apple Business Manager does the equivalent job for Macs, iPhones and iPads bought through a linked reseller.

One trap worth knowing about before you buy hardware: Windows Home cannot be managed this way. Laptops need Windows Pro or better. A retail laptop bought on special is often Home edition, and upgrading every one of them later is an avoidable cost.

2. Keeping everything patched

Intune pushes Windows and application updates on a schedule you define, and reports which devices have fallen behind. You can stage updates too, so a small test group gets them first and everyone else follows a week later if nothing breaks.

This matters because unpatched software remains one of the most common ways small businesses get compromised. Patching is two of the eight controls in the Essential Eight, and Intune is how most Microsoft shops meet them.

3. Enforcing a security baseline

Encryption on every drive, through BitLocker on Windows and FileVault on Mac. A screen lock after a few idle minutes. Local administrator rights removed from everyday accounts. Firewalls on. Macros blocked in Office documents from the internet.

Each of these is a single policy applied to the whole fleet, rather than a checklist someone works through device by device and inevitably misses one.

4. Deciding which devices are allowed in

Intune checks every device against your rules. Is it encrypted? Is it patched? Is the antivirus running? Conditional Access then uses that answer: a compliant device signs in normally, a non-compliant one is blocked from company email and files until it is fixed.

This is the piece that turns device management from paperwork into an actual control. Stolen credentials on their own stop being enough to get in.

5. Wiping a device when you need to

Lost, stolen, or leaving the business. A company laptop can be remotely wiped and reset. That single capability is usually what justifies the whole exercise the first time you need it.

Personal phones: you do not have to take them over

This is where small businesses get stuck. Staff check email on their own phones, and nobody wants their employer able to see their photos or wipe their device.

Intune handles this with app protection policies. Rather than enrolling the whole phone, you protect the work apps on it: Outlook, Teams, OneDrive, and the Office apps. You can then require a PIN to open them, block copying company data into personal apps, and stop files being saved outside the business's storage.

When someone leaves, you remove the company data from those apps and nothing else. Their photos, messages and personal accounts are untouched, and they never had to hand over control of a device they paid for.

For most small teams this is the right answer for personal phones. Full enrolment is better kept for devices the business owns.

When it is worth setting up

The honest threshold is lower than most people expect. It is worth doing properly when any of these are true:

• You have more than about ten devices. Below that, managing things by hand is tedious but survivable. Above it, the gaps become invisible. Smaller teams still benefit from encryption and clean offboarding, just with a lighter setup.
• Staff come and go. Every departure is a security event. Without central control, offboarding depends on someone remembering every device and every account.
• People work away from the office. Home networks, cafes and client sites are outside any perimeter. The device has to carry its own security.
• You handle sensitive data. Health, financial, legal, or anything a client would be upset to see leaked.
• A client or insurer is asking questions. Cyber insurance forms and client security questionnaires increasingly ask directly about device management, encryption and multi-factor authentication.

When Intune is the wrong tool

It is not always the answer, and we would rather say so.

• Your business runs on Google Workspace. Google's own endpoint management fits better than bolting Microsoft tooling onto a Google environment.
• You are almost entirely on Apple. A creative studio on Macs and iPhones may be better served by an Apple-first platform such as Jamf, Kandji or Mosyle. Intune manages Apple devices well enough, but the specialists are better at it.
• You are two people with no turnover. Turn on multi-factor authentication, enable encryption and automatic updates, and revisit the question when you hire.

The setup mistakes that cause real damage

Intune is powerful enough to lock an entire business out of its own systems in an afternoon. The mistakes we see most often:

Switching on Conditional Access before devices are compliant. Every device that has not been brought into line gets blocked at once, usually on a Monday morning. Report-only mode exists for exactly this reason. Use it first, see who would have been blocked, fix them, then enforce.

No emergency access account. At least one administrator account should be excluded from Conditional Access, protected with a long password stored securely offline, and used only in an emergency. Without it, a bad policy can leave nobody able to undo it.

Rolling out to everyone at once. Start with a pilot group of two or three people who will tell you when something breaks. Then a department. Then everyone.

Forcing full enrolment on personal phones. It generates resentment and resistance, and app protection policies achieve the business goal without it.

Treating setup as the finish line. Policies drift, devices age, and new threats change what a sensible baseline looks like. Someone needs to own it after launch.

What a rollout typically looks like

For a business with ten to fifty devices, a well-run rollout usually takes two to four weeks:

1. Assessment. Inventory every device, check hardware editions, confirm licensing, and agree the baseline.
2. Tenant preparation. Configure enrolment, build policies, set up the emergency account, and run Conditional Access in report-only mode.
3. Pilot. A small group enrols, uses their devices normally for a week, and reports anything that breaks.
4. Staged rollout. The remaining devices come across in groups, with compliance checked as each one lands.
5. Enforcement and handover. Conditional Access is switched on, offboarding is documented, and the business knows who owns what from here.

Existing devices can usually be brought across without a rebuild, although a clean reset through Autopilot gives the most consistent result where the timing allows.

On ongoing cost, managed device management generally sits somewhere between $8 and $20 per device per month, depending on what is included. We break that down alongside the rest of a security budget in our guide to what cyber security costs a small business.

The short version

If you are on Microsoft 365 Business Premium, you already own Intune. If nobody has set it up, that is the cheapest security improvement available to you.

Use it to build every device the same way, keep them patched, enforce encryption, block devices that fall out of line, and wipe them when they are lost or someone leaves. Protect the work apps on personal phones rather than taking the phones over. And roll it out gradually, because the tool that secures your business can also lock everyone out of it if it is switched on carelessly.
