Best Practices for Implementing Microsoft Intune: A Practical Guide to Secure, Scalable, and Effective Device Management 

As organisations continue to adopt cloud-first and hybrid strategies, managing endpoints effectively becomes central to operational success. Microsoft Intune offers a robust platform for device and application management, but its potential is only fully realised when implemented with a clear strategy and ongoing refinement. This guide consolidates practical insights and technical best practices, designed to be accessible from the IT intern to the CTO. 

1. Start with strategy, not settings 

Jumping straight into policy creation can lead to confusion and misalignment. Begin by identifying your organisational objectives: security posture, compliance requirements, user experience goals, and support capacity. From there, define a policy framework that supports these aims rather than simply enabling all available options. 

A solid starting point includes: 

• Device compliance policies for OS version, disk encryption, and malware protection 
• Configuration profiles tailored to device roles (e.g. BYOD vs corporate, student vs staff) 
• Conditional Access rules based on compliance, location, or user risk level 

Use consistent naming conventions, tag logically, and document policy purposes clearly to maintain clarity over time. 

2. Inventory, identity, and grouping: know what you have and who uses it 

Good device management starts with knowing what you’re managing. Use a comprehensive inventory process to capture all device types, Windows, macOS, Android, and iOS. Categorise devices by user role, location, or department, and use dynamic groups in Azure AD to automate classification. 

Asset tagging, naming conventions, and structured groups (e.g. ‘Admin_Laptops_UK’) will help you scope policies and apps with precision. Regular audits and automated reporting are key to preventing blind spots or policy misapplication. 

Identity also underpins effective security. Configure Azure AD with Conditional Access and Multi-Factor Authentication. Use Role-Based Access Control (RBAC) to delegate access according to role, not convenience. 

3. Configure with control: policies, compliance, and baselines 

Start with Microsoft’s Security Baselines for Windows, macOS, and Defender, then customise as needed. Core policies should enforce: 

• Full disk encryption (BitLocker, FileVault) 
• Strong PIN/password complexity 
• Endpoint protection in a healthy state 
• Up-to-date OS and patch levels 

Intune’s Compliance Policies define what “healthy” looks like for your organisation. Enforce encryption, OS versions, and device integrity, and define escalation paths for non-compliance, from user notifications to full Conditional Access blocks. 

For shared or kiosk-style devices, use Intune’s multi-user or kiosk profiles with automatic sign-out and profile cleanup. 

4. Application management: packaging, deployment, and updates 

Managing applications in Intune goes beyond deployment. It requires a complete lifecycle view: 

• Use Win32 for traditional EXE/MSI apps and MSIX, where suitable 
• Assign apps based on groups aligned to departments or roles 
• Leverage detection rules and dependencies to ensure correct sequencing 
• Supersede outdated versions using Intune’s built-in update mechanisms 

For complex or legacy software, tools like PowerShell scripts, custom installers, or packaging solutions may be required. Align packaging methods with the app’s complexity and criticality; one-size-fits-all rarely applies. 

Always test packages in a staging environment before full rollout. For BYOD, focus on App Protection Policies rather than full device enrolment. 

5. Testing, logging, and controlled rollout 

Deploy in phases, starting with pilot groups, ideally IT staff or motivated users. Validate enrolment, Conditional Access, compliance reporting, and application installs. Log changes, version all scripts, and keep a running changelog. 

Use tools like: 

• Endpoint Analytics for deployment outcomes and boot performance 
• Diagnostic logs for app installs and policy conflicts 
• Proactive Remediations and Scripts to resolve recurring issues 

A controlled rollout reduces disruption and allows iterative refinement. 

6. Monitor and optimise: visibility that drives action 

Effective monitoring focuses on actionable insights: 

• Set alerts for policy violations, device risk, and enrolment failures 
• Review dashboards weekly to track compliance drift or user issues 
• Integrate with Defender for Endpoint and Sentinel for correlation and SIEM functionality 

Feedback loops matter: solicit input from end users and support teams. Balance security with usability; unhappy users find ways around your controls. 

7. Automate where sensible, maintain what you build 

Use Graph API and PowerShell to automate tasks such as: 

• Device onboarding/offboarding 
• Application deployment across multiple tenants 
• Reporting on compliance and policy assignments 

But automation isn’t fire-and-forget. Store scripts in source control, add comments, and schedule regular reviews to ensure they still align with your goals. 

Final thoughts: build with security, grow with feedback 

Intune is not just a management tool, it’s part of a broader security and productivity ecosystem. Success comes from a deliberate strategy, clean structure, ongoing feedback, and constant refinement. 

Begin with essential security controls. Roll out gradually. Document everything. And remember that Intune’s value lies in its flexibility, so tailor it to your needs, not someone else’s template. 

By following these practices, your organisation can build a scalable, secure, and sustainable Intune environment that supports users while reducing risk.
