What you’ll need before you start
- Intune subscription with Conditional Access policies
- GlobalProtect gateway and portal configured in your Palo Alto Networks environment
- Devices enrolled in Intune iOS, Android, Windows
- Administrative access to Microsoft Endpoint Manager admin center and GlobalProtect management console
- A clear list of apps you want to route through the VPN package IDs for mobile apps, executables for desktop
Plan and design considerations
- Scope: Decide which apps require VPN access. For example, finance and HR apps might need full secure access, while productivity apps may not.
- Traffic routing: Determine whether to route all traffic for a given app or only corporate resources split tunneling. Per-app VPN usually focuses on corporate resource traffic through the VPN while other traffic goes directly to the internet.
- User experience: Consider whether to force VPN on app launch or allow a manual toggle within the app’s settings.
- Compliance: Ensure your policy aligns with data residency, logging requirements, and incident response plans.
GlobalProtect and Intune: Architecture basics
- GlobalProtect acts as the VPN gateway and client, providing secure tunnels to your corporate network.
- Intune per-app VPN creates a VPN profile at the device level, which can be scoped to specific apps, so only those apps use the VPN tunnel.
- The combination gives you fine-grained control: you decide which apps tunnel, when, and under what conditions.
Step-by-step deployment guide
Step 1: Define the per-app VPN policy in GlobalProtect
- Create a VPN policy that supports per-app routing. You’ll need:
- Gateway address and portal URL
- Authentication method machine certificate, user certificate, or SAML
- Split-tunnel rules which destinations require VPN
- Document the apps that will trigger the VPN, including their package IDs iOS/Android or executable names Windows.
Step 2: Prepare Intune for per-app VPN
- In the Intune admin center, navigate to Apps > App configuration policies or the per-app VPN area if your layout shows it.
- Create a new per-app VPN policy and select the platform iOS, Android, Windows.
- Set the VPN provider to GlobalProtect:
- For iOS: Use the GlobalProtect VPN type and specify the portal and gateway, along with authentication type.
- For Android: Configure the VPN per-app VPN profile with the GlobalProtect app as the VPN client, including the gateway address and portal.
- For Windows: Use the per-app VPN Preview or GA depending on your version and map the GlobalProtect VPN client to specific apps.
Step 3: Map apps to the VPN profile
- Create an app association policy that links selected apps to the per-app VPN profile.
- For iOS/Android, provide the bundle ID or package name. For Windows, supply the executable path or AppID if needed.
- Example: “FinanceMobile” and “HRMobile” apps route through VPN; “Email” app remains outside VPN if allowed.
Step 4: Deploy to user groups
- Assign the per-app VPN profile and associated apps to the intended user groups or devices.
- Use a phased rollout: pilot group first, then broader deployment to minimize user impact.
- Ensure devices are enrolled in Intune and have the latest GlobalProtect client installed.
Step 5: Configure authentication and access controls
- Tie VPN access to Conditional Access policies in Azure AD. Require compliant devices, MFA where appropriate, and device-based conditions.
- Consider using device certificates for stronger authentication, especially for off-network access.
Step 6: Test the setup thoroughly
- On a test device, launch the target app and verify traffic is routed via GlobalProtect.
- Validate that non-target apps do not use the VPN unless required by your policy.
- Check gateway connectivity, DNS resolution, and resource access internal apps, intranet sites, file shares.
- Monitor logs for failed tunnels, certificate issues, or policy mismatches.
Step 7: Monitor and maintain
- Use Intune and GlobalProtect dashboards to monitor VPN health, tunnel status, and app usage.
- Set alert rules for VPN outages or authentication failures.
- Periodically review app lists, update mappings, and adjust split-tunnel rules as needed.
Best practices and tips
- Start with a narrow scope: Begin with two or three critical apps to validate the workflow before scaling.
- Prefer certificate-based authentication to reduce password exposure and simplify revocation.
- Maintain up-to-date app lists: As apps update, their package IDs or executables can change, requiring policy updates.
- Document user onboarding steps: Provide clear quick-start guides to reduce support tickets.
- Plan for offline scenarios: Ensure there’s a safe fallback if VPN connectivity is temporarily unavailable.
- Regularly test failover: Simulate gateway failure to ensure users can reconnect smoothly.
Security considerations
- Principle of least privilege: Only route necessary apps through the VPN to minimize exposure.
- Data protection: Ensure encryption is enabled end-to-end and that sensitive data is not stored in unencrypted form on devices.
- Logging: Balance visibility with privacy. Collect essential logs for audit purposes without over-logging user data.
- Compliance: Align with regional data protection laws and enterprise security policies.
Platform-specific notes
- iOS:
- Use Managed App Configuration to control VPN behavior per app.
- Ensure the GlobalProtect app is deployed via Intune and kept up to date.
- Test App Transport Security ATS settings if your resources require strict TLS configurations.
- Android:
- Handle per-app VPN with Android’s Network Security Configuration and the GlobalProtect app.
- Watch for battery and background activity considerations; per-app VPN can affect background data usage.
- Windows:
- Per-app VPN on Windows requires careful mapping to UWP or Win32 apps.
- Test with corporate resources that use Kerberos or NTLM authentication as appropriate.
- Ensure Windows Defender firewall rules don’t block required VPN traffic.
Real-world scenarios and examples
- Scenario A: Finance app accessed only through VPN
- Apps: FinanceMobile iOS/Android, FinanceDesktop Windows
- Outcome: All financial data traffic is secured via GlobalProtect; personal apps stay outside VPN.
- Scenario B: Remote support portal
- App: SupportPortal Windows
- Outcome: Admins access internal portals through VPN; other work apps bypass VPN for better performance.
- Scenario C: BYOD policy with selective VPN
- Apps: HRMobile, PayrollWeb via browser
- Outcome: Sensitive HR data tunnels through VPN; non-sensitive apps use direct access.

- Implement automatic re-connect logic: Minimize user disruption during temporary network drops.
- Leverage policy-based access controls: Combine with device posture checks OS version, encryption status for higher security.
- Regularly audit app usage: Identify apps that frequently trigger VPN and assess whether adjustments are needed.
