Device security isn't optional anymore. In 2026, organisations managing hybrid workforces face increasingly complex security challenges, and Microsoft Intune device compliance policies have become essential for IT teams looking to protect corporate data.
If you're working in IT helpdesk support or managing Microsoft 365 environments, understanding how to implement device compliance policies will set you apart. This guide walks you through everything you need to know.
Microsoft Intune device compliance policies define the rules and settings that devices must meet to connect to your organisation's network and access corporate resources. Think of them as security checkpoints that ensure every device meeting your company standards before granting access.
These policies work across multiple device types:
When a device fails to meet compliance requirements, you can automatically restrict access to company email, cloud applications, and data until the issue is resolved. This conditional approach means you're not completely locking out employees, but rather encouraging them to maintain security standards.
The threat landscape has shifted considerably. According to recent industry data, organisations without device compliance policies experience 3.5 times more security incidents than those with robust mobile device management strategies.
Remote work has become the norm. Your employees are connecting from home offices, coffee shops, and temporary locations. Without clear compliance policies, you're essentially allowing unvetted devices to access sensitive business information.
Compliance and regulatory requirements matter too. Whether you're in healthcare, finance, or any regulated industry, device compliance policies demonstrate to auditors that you take security seriously. They're often required for GDPR, HIPAA, and other compliance frameworks.
Before setting up your first policy, understand what elements you can control:
Device Health Requirements
You can enforce that devices have updated security patches, antivirus software running, and encryption enabled. Windows devices must meet specific Windows Defender requirements, whilst iOS devices need specific iOS versions.
Password Policies
Set minimum password length (typically 6-8 characters for mobile, 8-12 for computers), require complex passwords with mixed case and numbers, and set password expiration timeframes.
Encryption and Storage
Enforce storage encryption on all devices. This means if a device is lost or stolen, the data remains protected. You can also require specific encryption standards.
Threat Detection
Configure policies to detect and respond to threats on enrolled devices. Mobile Threat Defense (MTD) partnerships with third-party providers add an extra security layer.
Device OS Versions
Specify minimum and maximum operating system versions. This prevents devices running outdated software from accessing company resources.
Log into the Microsoft Intune admin centre using your Microsoft 365 account. Navigate to Devices, then select Compliance Policies. Click Create Policy and choose your device platform.
You'll see sections for different compliance areas. Start simple. Don't overwhelm users with every possible requirement immediately.
Recommended First Policy (Windows Devices)
This gives you solid baseline security without creating support tickets from frustrated users.
Mobile Device Policy (iOS/Android)
Here's the crucial bit. Once you've created a policy, you need to define what happens when devices fail compliance checks.
You have several options:
Immediate Actions
Escalation Actions
Set automatic actions if the device remains non-compliant for specific periods. After 30 days of non-compliance, you might retire the device (especially important for corporate-owned devices).
Progressive Approach
A sensible strategy involves progressive enforcement:
This gives users time to fix issues rather than hitting them with immediate access loss.
Don't apply policies to everyone at once. Use Azure AD groups to roll out gradually.
Create a pilot group of 50-100 power users comfortable with technology changes. Deploy the policy there first, gather feedback, and refine. Then expand to additional groups.
This approach prevents mass support calls and gives you time to troubleshoot issues.
Overcomplicating Initial Policies
Start with essentials: encryption, password requirements, and OS versions. Add complexity later as users adapt.
Not Testing Thoroughly
Test policies with your own devices before deploying to 5,000 users. You'll catch configuration errors and unintended consequences.
Forgetting Exception Groups
Some users need exceptions (executives with older devices, contractors with personal equipment). Create exception groups and manage them separately.
Ignoring User Communication
Tell users what's coming. Send advance notifications explaining why you're implementing policies and what devices need to meet. Compliance works better with understanding.
Not Monitoring Compliance Reports
Once deployed, check your compliance reports weekly. How many devices are non-compliant? What's the primary reason? Use this data to refine policies.
Track these key metrics:
A healthy compliance programme should see 90%+ of devices remaining compliant after the initial deployment phase.
Device compliance policies represent a significant investment in organisational security. Getting them right requires understanding not just the technology, but also how to manage user expectations and provide proper training.
