MDM Rollout
Mobile Device Management rollout provisions centralised control over organisational endpoints through agent enrollment, policy application, and compliance monitoring. This task establishes the technical infrastructure for device security, application deployment, and remote management capabilities across iOS, Android, Windows, and macOS platforms.
Prerequisites
| Requirement | Detail |
|---|---|
| MDM platform | Selected and provisioned (Intune, Jamf, Kandji, Workspace ONE, or open source alternative) |
| Identity provider | Configured with MDM integration; SCIM provisioning recommended |
| Apple Business Manager | Enrolled with MDM server token configured (for iOS/macOS) |
| Android Enterprise | Organisation registered with managed Google Play configured |
| Certificates | Apple Push Notification service (APNs) certificate valid; SCEP or certificate authority configured |
| Policies | Device compliance, configuration profiles, and application policies defined and approved |
| Device inventory | Current inventory with ownership classification (corporate vs BYOD) |
| Network access | Enrollment URLs accessible from all network locations including field offices |
| Permissions | MDM administrator role; Intune Administrator or equivalent |
| Time estimate | 4-8 weeks for full rollout depending on device count |
Verify APNs certificate validity before beginning enrollment:
# Check APNs certificate expiry (if exported locally)openssl x509 -in apple_mdm_push_cert.pem -noout -dates
# Expected output shows certificate validity period# notBefore=Jan 5 00:00:00 2025 GMT# notAfter=Jan 5 23:59:59 2026 GMTAPNs certificate expiry
APNs certificates expire annually. Set calendar reminders 30 days before expiry. Certificate renewal requires the same Apple ID used for initial creation. Loss of this Apple ID forces complete iOS re-enrollment.
Confirm network connectivity from a test device to required endpoints:
# Test connectivity to Microsoft Intune endpoints (Windows)Test-NetConnection -ComputerName enrollment.manage.microsoft.com -Port 443Test-NetConnection -ComputerName portal.manage.microsoft.com -Port 443
# For Jamf ProTest-NetConnection -ComputerName yourinstance.jamfcloud.com -Port 443Procedure
Device inventory and prioritisation
- Export current device inventory from existing asset management or directory services. Include device type, operating system version, ownership (corporate or BYOD), user assignment, and location:
# Export from Azure AD/Entra ID az ad device list --query "[].{Name:displayName, OS:operatingSystem, OSVersion:operatingSystemVersion, TrustType:trustType}" -o tsv > device_inventory.tsvFor organisations without centralised inventory, distribute a device registration form collecting: device make/model, serial number, operating system version, primary user, and whether the device accesses organisational data.
Classify devices into enrollment waves based on risk and complexity:
Wave Criteria Typical timeline Pilot IT staff devices, volunteers from each platform Week 1-2 Wave 1 Corporate-owned devices at headquarters Week 3-4 Wave 2 Corporate-owned devices at regional/country offices Week 4-5 Wave 3 BYOD devices with willing early adopters Week 5-6 Wave 4 Remaining BYOD devices, field devices Week 6-8 Identify minimum operating system versions for enrollment. Devices below these thresholds require upgrade or replacement before MDM enrollment:
Platform Minimum version Rationale iOS 15.0 Managed Apple ID support, declarative management Android 10.0 Android Enterprise work profile improvements Windows 10 21H2 Windows Autopilot enhancements macOS 12.0 Declarative device management, platform SSO Flag devices requiring pre-enrollment action:
- Devices below minimum OS version: schedule upgrade
- Devices with existing MDM enrollment: coordinate unenrollment
- Devices with full-disk encryption using local keys: document recovery keys before enrollment
Platform enrollment configuration
iOS and iPadOS enrollment
- Configure Apple Business Manager integration. In your MDM console, upload the MDM server token downloaded from Apple Business Manager:
MDM Console > Settings > Apple Business Manager Upload: AppleBM_Token_yourorg.p7m Default device assignment: [Your MDM server]For devices purchased through Apple or authorised resellers, enable Automated Device Enrollment (formerly DEP). This provides zero-touch enrollment and supervision.
- Create an iOS enrollment profile specifying supervision status and authentication:
<!-- iOS Enrollment Profile Configuration --> <dict> <key>PayloadDisplayName</key> <string>Organisation MDM Enrollment</string> <key>IsSupervised</key> <true/> <key>AwaitDeviceConfigured</key> <true/> <key>ConfigurationWebURL</key> <string>https://mdm.example.org/enroll</string> </dict>Supervised mode enables additional management capabilities: app installation without user prompt, restriction bypass for enterprise apps, single app mode, and global HTTP proxy. Corporate-owned devices should always be supervised. BYOD devices cannot be supervised without full device wipe and re-enrollment through Apple Configurator.
- Configure enrollment authentication. For corporate devices with Automated Device Enrollment, authentication occurs during Setup Assistant:
Setup Assistant > Authentication Method: Azure AD / Entra ID Require MFA: Yes Skip Setup Assistant panes: Location Services, Siri, Screen Time, Apple PayFor BYOD enrollment via Company Portal app, users authenticate with organisational credentials after installing the app from the App Store.
- Assign enrollment profiles to device serial numbers in Apple Business Manager. Devices sync to MDM within 24 hours, or force sync:
# Intune: Sync Apple Business Manager devices # Navigate to: Devices > iOS/iPadOS > iOS/iPadOS enrollment > Enrollment program tokens > [Token] > SyncAndroid enrollment
- Connect Android Enterprise to your MDM platform. Navigate to the managed Google Play configuration and complete the organisation binding:
MDM Console > Android Enterprise > Connect Google Account: admin-mdm@example.org (dedicated account, not personal) Organisation: Your Organisation NameThe binding creates a managed Google Play organisation. Applications approved in managed Google Play become available for deployment to enrolled devices.
Select enrollment method based on device ownership and Android version:
Method Use case Android version Device ownership Work profile Personal device with work container 5.0+ BYOD Fully managed Corporate device, complete control 5.1+ Corporate Dedicated device Kiosk, shared device, single purpose 6.0+ Corporate Work profile on company-owned device Corporate device with personal use permitted 11.0+ Corporate For most organisations, work profile serves BYOD devices while fully managed serves corporate devices.
Configure enrollment for fully managed corporate devices. Create an enrollment token:
Android enrollment > Corporate-owned fully managed user devices Token name: Corporate-Enrollment-2025 Expiry: 90 days QR code: GenerateThe QR code encodes the enrollment token. During device setup, tapping the welcome screen six times reveals the QR reader. Alternatively, enter the enrolment token afw#setup during initial device setup to trigger enrollment.
- Configure work profile enrollment for BYOD. Users install the company app (Company Portal, Workspace ONE Intelligent Hub, or equivalent) from the Play Store and authenticate:
Android enrollment > Personal devices with work profile Enrollment restriction: All users in group "BYOD-Permitted-Users" Personal profile: Allow (do not block personal apps) Work profile applications: Managed Google Play onlyWindows enrollment
- Configure Windows automatic enrollment for Azure AD/Entra ID joined devices. In your MDM console, enable the Azure AD integration:
MDM Console > Windows enrollment > Automatic enrollment MDM user scope: All (or specific group) MAM user scope: None (MDM takes precedence)Devices joining Azure AD automatically enroll in Intune if the user is within scope. This provides seamless enrollment for new corporate devices.
- For existing Windows devices not yet Azure AD joined, configure bulk enrollment using a provisioning package or Windows Autopilot:
# Create provisioning package for bulk enrollment # Windows Configuration Designer approach
# Alternative: Register device hash for Autopilot Install-Script -Name Get-WindowsAutoPilotInfo Get-WindowsAutoPilotInfo -OutputFile autopilot_devices.csvUpload autopilot_devices.csv to Intune under Devices > Windows > Windows enrollment > Devices.
- Configure enrollment restrictions to prevent unmanaged personal Windows devices:
Windows enrollment > Enrollment restrictions Device type restriction: Create Name: Corporate-Windows-Only Platform: Windows (MDM) Personally owned: Block Assignment: All UsersOrganisations permitting Windows BYOD should create a separate restriction with appropriate compliance requirements.
- Configure Windows Hello for Business as part of enrollment. This replaces passwords with certificate-based authentication:
Windows enrollment > Windows Hello for Business Configure Windows Hello for Business: Enabled Use a Trusted Platform Module (TPM): Required Minimum PIN length: 6 Biometric authentication: AllowedmacOS enrollment
Configure Automated Device Enrollment for corporate Mac devices through Apple Business Manager, following the same MDM server token process as iOS.
Create a macOS enrollment profile:
macOS enrollment > Enrollment program Profile name: Corporate-Mac-Enrollment User affinity: Enroll with User Affinity Authentication: Company Portal Locked enrollment: Yes (prevents user from removing MDM profile)- For existing Mac devices not purchased through ABM, configure user-initiated enrollment. Users navigate to the enrollment URL and authenticate:
Enrollment URL: https://enrollment.manage.microsoft.com/enrollmentserver/discovery
# Alternative for Jamf Pro sudo profiles -e -server https://yourinstance.jamfcloud.com/enroll- Configure Bootstrap Token escrow for Apple Silicon Macs. The bootstrap token enables MDM to authorise kernel extensions and software updates:
macOS enrollment > Settings Bootstrap Token: Enabled Escrow location: MDM serverWithout bootstrap token escrow, macOS prompts for local administrator credentials during software updates and kernel extension approval, breaking automated management.
Policy configuration
Configure policies before enrolling production devices. Policies fall into three categories: compliance policies that define minimum security requirements, configuration profiles that push settings, and application policies that deploy software.
- Create compliance policies establishing minimum device security. Non-compliant devices trigger defined actions (mark non-compliant, block access, wipe device):
# Example compliance policy structure compliance_policy: name: "Organisation-Baseline-Compliance" platforms: [iOS, Android, Windows, macOS]
rules: - encryption_required: true - min_os_version: iOS: "15.0" Android: "10.0" Windows: "10.0.19043" # 21H1 macOS: "12.0" - password_required: true - password_min_length: 6 - jailbreak_detection: block # iOS only - device_threat_level: medium_or_below # if using MTD
non_compliance_action: - mark_noncompliant: immediately - block_access: after_3_days - send_notification: immediately - wipe_device: never # or "after_90_days" for corporate- Create configuration profiles pushing required settings. Separate profiles by function to enable granular assignment:
Profile: WiFi-Corporate Platform: All Settings: - SSID: CorpWiFi - Security: WPA2-Enterprise - Authentication: PEAP-MSCHAPv2 - Identity: {{userPrincipalName}}
Profile: Restrictions-BYOD Platform: iOS, Android Settings: - Allow backup to iCloud: Yes (BYOD may backup personal data) - Managed Open In: Required (work data stays in work apps) - Copy/paste between managed and unmanaged: Blocked
Profile: Restrictions-Corporate Platform: iOS, Android Settings: - Allow backup to iCloud: No - Allow app installation: Managed apps only - Camera: Allowed (or restricted for specific use cases)- Configure conditional access policies integrating MDM compliance with identity:
Conditional Access Policy: Require-Compliant-Device
Assignments: Users: All users Exclude: Break-glass accounts, Service accounts
Cloud apps: All cloud apps
Conditions: Device platforms: All platforms Client apps: Browser, Mobile apps and desktop clients
Access controls: Grant: Require device to be marked as compliant
Session: Sign-in frequency 12 hoursThis policy blocks access to organisational resources from devices not enrolled and compliant with MDM policy. Implement after pilot testing to avoid locking out users.
- Configure application deployment policies. Push required applications automatically; make optional applications available in the company app store:
App deployment: Required apps (auto-install): - Microsoft Authenticator - Organisational app (custom LOB app) - Mobile Threat Defence app (if applicable)
Available apps (user choice): - Microsoft Office suite - Adobe Acrobat Reader - Other productivity appsPilot group testing
- Create a pilot group of 10-20 users spanning all platforms and representing different roles. Include at least one IT staff member per platform, one field-based user, and users with both corporate and BYOD devices:
Pilot Group: MDM-Pilot Members: - IT staff: 5 users (1 per platform + 1 Windows/iOS dual user) - Programme staff: 5 users - Finance staff: 3 users - Field staff: 4 users - Executive: 1 user (visible champion)- Assign enrollment and compliance policies to the pilot group only:
Policy: Organisation-Baseline-Compliance Assignment: MDM-Pilot group Exclude: None
Profile: WiFi-Corporate Assignment: MDM-Pilot group
Conditional Access: Require-Compliant-Device Assignment: MDM-Pilot group (not all users yet)Guide pilot users through enrollment and document issues. Create a pilot tracking spreadsheet:
User Device Platform Enrollment date Issues Resolution jsmith iPhone 14 iOS 17.2 2025-01-15 None Enrolled successfully ajohansson Pixel 7 Android 14 2025-01-15 Work profile creation failed Factory reset resolved mchen Surface Pro Win 11 2025-01-16 Compliance policy timeout Extended sync period Run pilot for minimum two weeks. Verify:
- All platforms enroll successfully
- Compliance policies evaluate correctly
- Applications deploy as expected
- Conditional access blocks non-compliant devices
- Email, calendar, and files accessible from enrolled devices
- Remote wipe functions (test on designated test device)
- Field connectivity scenarios work
Refine policies based on pilot feedback. Common adjustments:
- Extend compliance grace period if field devices sync infrequently
- Adjust password requirements if users struggle with mobile input
- Add approved applications discovered during pilot
- Modify WiFi profiles for additional office locations
Staged rollout
- Communicate rollout timeline and requirements to all users. Send initial notification two weeks before their wave:
Subject: Mobile Device Management Enrollment - Action Required by [Date]
[Organisation] is implementing Mobile Device Management (MDM) to protect organisational data on mobile devices. You will need to enroll your device(s) by [date].
What you need to do: - Corporate device: Follow the enrollment guide at [link] - Personal device accessing work email: Enroll or switch to web-only access
Why this matters: - Protects sensitive data if your device is lost or stolen - Enables remote wipe of work data only (personal data unaffected on BYOD) - Required for continued access to email, files, and organisational apps
Support: Contact IT help desk for enrollment assistance- For BYOD devices, obtain explicit consent. Users must understand what MDM can and cannot see or control:
BYOD Consent Acknowledgement
By enrolling your personal device, you consent to:
What IT CAN see: - Device make, model, and serial number - Operating system version - Installed organisational apps - Device compliance status (encryption, passcode) - Device location (only if enabled and disclosed)
What IT CANNOT see: - Personal apps (outside work profile on Android) - Personal photos, messages, browsing history - Personal email accounts
What IT CAN do: - Remove organisational apps and data - Enforce work passcode requirements - Block access to organisational resources if non-compliant
What IT CANNOT do: - Wipe personal data (BYOD work profile only removes work data) - Access personal accounts - Track location without explicit consent and disclosure
[ ] I acknowledge and consent to MDM enrollment
Signature: ________________ Date: ________- Execute wave 1 enrollment. Expand policy assignment to include the wave 1 group:
# Update policy assignments Policy: Organisation-Baseline-Compliance Assignment: MDM-Pilot, Wave-1-HQ-Corporate
Conditional Access: Require-Compliant-Device Assignment: MDM-Pilot, Wave-1-HQ-Corporate- Provide enrollment support during each wave. For large waves, schedule drop-in enrollment sessions where IT staff assist with enrollment. Monitor enrollment completion:
# Intune: Export enrollment status # Graph API query for enrollment status GET https://graph.microsoft.com/v1.0/deviceManagement/managedDevices?$select=deviceName,enrolledDateTime,complianceState,userPrincipalNameFollow up with non-enrolled users. Send reminder at wave midpoint and final reminder three days before deadline. After deadline, conditional access blocks non-enrolled devices from organisational resources.
Proceed through subsequent waves, adjusting pace based on support capacity and issue rate. Do not begin next wave until previous wave reaches 90% enrollment and critical issues are resolved.
Compliance monitoring setup
- Configure compliance reporting dashboard. Most MDM platforms provide built-in dashboards; supplement with custom reports:
Dashboard widgets: - Total enrolled devices by platform - Compliance percentage by platform - Non-compliant device count with top reasons - Enrollment trend (devices enrolled per week) - Devices not checked in (last 7/14/30 days)- Configure alerts for compliance drift:
Alert: High-Noncompliance-Rate Trigger: Non-compliant devices exceed 10% of enrolled Action: Email to IT security lead
Alert: Stale-Device Trigger: Device not checked in for 30 days Action: Email to device owner and manager
Alert: Jailbreak-Detection Trigger: iOS device detected as jailbroken Action: Immediate block, email to security teamEstablish regular compliance review cadence:
Review Frequency Participants Focus Daily check Daily IT operations New enrollments, critical alerts Weekly review Weekly IT team Compliance trends, stale devices Monthly report Monthly IT management Policy effectiveness, exception requests Quarterly audit Quarterly IT + Security Policy review, gap analysis Document exception process for devices that cannot meet compliance requirements:

Personal devices require different treatment than corporate devices. The work profile model on Android and managed apps on iOS create a container for organisational data without controlling the entire device.
- Configure work profile enrollment for Android BYOD. Work profile creates a separate container with distinct app copies:
Android BYOD Policy: Enrollment type: Work profile on personally-owned devices
Work profile settings: - Copy/paste to personal profile: Blocked - Screen capture: Allowed (or blocked for sensitive roles) - Work profile lock: Required, separate from device lock - Work app notifications: Show content when locked (optional)
Personal profile visibility: None (MDM cannot see personal apps)
Wipe scope: Work profile only (personal data preserved)Configure managed app protection for iOS BYOD without full MDM enrollment (MAM-only):
For organisations permitting access without device enrollment, Mobile Application Management (MAM) protects data within managed apps:
App Protection Policy: iOS-BYOD-MAM
Data protection: - Backup org data to iCloud: Block - Send org data to other apps: Policy managed apps only - Receive data from other apps: All apps - Save copies of org data: Block - Org data to native contacts: Block
Access requirements: - PIN for access: Required - PIN length: 6 - Biometric instead of PIN: Allowed
Conditional launch: - Max OS version: None (allows older devices) - Jailbroken devices: Block accessMAM-only provides less visibility and control than full MDM enrollment. Use only when device enrollment is not feasible.
- Configure selective wipe capability to remove only organisational data:
Wipe options: Corporate device: Full device wipe (returns to factory) BYOD with work profile: Work profile removal only MAM-only device: Remove managed app data onlyVerification

| Symptom | Cause | Resolution |
|---|---|---|
| iOS enrollment fails with “Profile Installation Failed” | APNs certificate expired or invalid | Renew APNs certificate in Apple portal; re-upload to MDM. Requires same Apple ID as original. |
| Android work profile creation fails | Insufficient storage space | Free at least 1GB before work profile creation. Work profile duplicates several system apps. |
| Android enrollment shows “Device not supported” | Device not Android Enterprise certified or outdated Android version | Check Android Enterprise Partner Directory for certification. Upgrade OS or replace device. |
| Windows device shows “Enrollment failed 0x80180026” | Enrollment server unreachable | Verify firewall allows outbound 443 to enrollment.manage.microsoft.com. Check proxy configuration. |
| Windows device enrolled but policies not applying | Intune sync delay or policy conflict | Force sync: Settings > Accounts > Access work or school > [Account] > Info > Sync. Check for conflicting GPO. |
| macOS enrollment hangs at “Downloading profile” | MDM profile URL blocked or certificate trust issue | Verify Apple root certificates trusted. Check proxy not intercepting SSL to MDM server. |
| Compliance policy shows “Not evaluated” | Device enrolled but initial compliance check not complete | Wait 15-30 minutes for initial evaluation. Force sync from device. Verify device meets minimum OS version. |
| Conditional access blocks enrolled, compliant device | AAD device registration incomplete or stale | Re-register device with Azure AD. Check Azure AD > Devices for duplicate entries. |
| User cannot install required apps | Managed Google Play / Apple Business Manager not linked | Verify enterprise app store configuration. Check app is approved/licensed for user. |
| Work profile apps crash on launch | VPN or firewall blocking managed app traffic | Ensure app endpoints accessible. Check per-app VPN configuration if applicable. |
| BYOD users refuse enrollment citing privacy concerns | Unclear communication about MDM capabilities | Review and share the MDM capability disclosure. Offer MAM-only alternative if policy permits. |
| Device location unavailable when requested | Location services disabled or not configured | Enable location services policy (requires user consent disclosure). Check device is online. |
| Selective wipe removes personal data | Incorrect wipe command issued on BYOD | Always verify device ownership before wipe. Use “Remove company data” not “Factory reset” for BYOD. |
| Windows Hello enrollment fails | TPM not available or disabled | Enable TPM in BIOS. Verify TPM 2.0 present with tpm.msc. Consider allowing non-TPM for older hardware. |
| Bulk enrollment via provisioning package fails | Package not signed or expired | Regenerate provisioning package. Verify not expired. Sign with code signing certificate. |
