Securing Remote-Work Devices With Intune

In remote work, the company computer leaves the corporate perimeter: a home Wi-Fi network shared with the whole family, no corporate firewall, often mixed with personal use. The device becomes your new security perimeter, your first and sometimes only line of defense. If it is not managed remotely, you lose all visibility and control over what reaches your data.

The good news is that a well-managed device is just as safe at home as in the office. The secret is not to recreate the corporate network in every employee's home, but to move security onto the device itself: define what a healthy machine looks like, continuously verify that it is, and grant access only on that condition. Intune does exactly this, remotely and without the user having to intervene.

Set clear compliance rules

The first building block is defining what a healthy device looks like, then granting access only to those that meet the rules. Intune continuously evaluates every device, wherever it is, and immediately flags any drift from your security standard. This evaluation runs on its own, in the background, so you no longer depend on a user remembering to check their own machine or on a technician physically inspecting it. The device reports its state, and your policy decides what happens next, consistently across the whole fleet.

• Up-to-date operating system, no obsolete versions or known flaws.
• Encrypted disk (BitLocker on Windows, FileVault on macOS).
• Defender antivirus active, with real-time and cloud protection.
• Strong lock code and automatic lock after inactivity.

Compliance only matters when tied to access

Evaluating compliance is not enough: you must act on it. That is the role of Conditional Access, which denies access to resources the moment a device falls out of compliance. A machine whose encryption is turned off or whose antivirus has failed automatically loses access to email and files, until it comes back into line. The rule thus becomes active, not merely declarative.

Keep updated and connect securely

A remote device must stay up to date at all times and reach internal resources without exposing the company to the internet. Intune handles both remotely and automatically, with no user intervention and no trip to the office.

• Windows and app updates deployed and tracked automatically.
• VPN configuration pushed from Intune, with no manual setup or typos.
• Conditional Access requiring a compliant device for every connection to resources.
• Remote wipe in case of loss, theft, or an employee's departure.

Combined with Conditional Access, this management ensures a device outside the walls meets exactly the same security level as in the office. The user works normally, with no added friction; protection follows them everywhere and runs in the background, wherever they connect from. The VPN deserves particular attention here: pushed from Intune, it avoids manual configuration errors and guarantees that every employee connects the same way, with the same security settings, rather than following an improvised procedure that differs on each machine. Consistency is itself a security property, because a single misconfigured device is often all an attacker needs.

The lifecycle: onboarding and offboarding

Remote management also pays off concretely the day an employee leaves the company or changes roles. Without it, recovering data and cutting off a remote worker's access is a headache, especially if they never come back to the office. With Intune, you remove their access, selectively wipe the corporate data, and reassign the device remotely, in a few clicks.

The same infrastructure that protects your devices day to day therefore also streamlines onboarding and offboarding, two moments when security gaps are common and expensive. A new hire receives a device that is already compliant and ready to use thanks to automated provisioning; a leaver has their access revoked and corporate data wiped without a technician handling the machine. You keep control of every device across its whole lifecycle, not just while it is actively in use by one person.

A concrete example

An SMB moves half its workforce to permanent remote work. At first, each employee configured their own VPN, sometimes skipped updates, and nobody knew which machines were actually encrypted. An internal audit reveals that several devices had neither an up-to-date antivirus nor active encryption, while still reaching client files.

After enrolling the devices in Intune, the situation turns around. Compliance rules enforce encryption, antivirus, and updates; Conditional Access blocks any non-compliant device; the VPN is pushed automatically, with no typing errors. Within a few weeks, management has a real-time view of each device's compliance, and the home machines reach the same security level as in the office, with no extra effort for the users.

Common mistakes to avoid

Securing remote work often fails on organizational gaps more than tooling. Here are the most common pitfalls.

• Letting users configure VPN and security themselves, a source of inconsistency.
• Evaluating compliance without tying it to Conditional Access, which makes it decorative.
• Counting on a return to the office to apply patches, which never happens.
• Forgetting disk encryption, even though machines travel outside the walls.
• Neglecting the offboarding procedure, leaving access and data active after departure.

How AuPoint secures your remote work

AuPoint is a SaaS that makes Intune security and compliance easy, with no PowerShell. The platform deploys these compliance, encryption, update, and VPN policies in a few clicks, with recommended settings, an impact preview before applying, and one-click rollback. Your remote-work devices reach office-grade security, aligned with ISO 27001 and NIS2, and you keep a clear, real-time view of which machines are compliant and which need attention. You spend your time on your business rather than on the console, while your fleet stays protected wherever your people work.

Frequently asked questions

Is a VPN enough to secure remote work?

No. The VPN protects the connection to internal resources, but it guarantees neither disk encryption, nor an up-to-date machine, nor the absence of malware. Remote-work security rests on the state of the device itself, verified by Intune compliance and Conditional Access.

Can you secure a personal device used for work?

Yes, with suitable approaches. Intune can fully manage a corporate device, or protect only the work data on a personal device through app management. The choice depends on your policy, but in both cases you keep control of the company's data.

What happens if a device becomes non-compliant?

Conditional Access denies it access to resources until it returns to compliance. The user is usually guided to fix the problem — re-enable encryption, install an update — then automatically regains access. Protection stays active continuously, with no manual intervention.
