Why Per-App VPN Matters for iOS and Intune
Per-App VPN is a targeted VPN solution that tunnels traffic only from specified apps through your VPN gateway. This approach offers several benefits:
- Faster device performance and better battery life since not all traffic goes through the VPN.
- Granular security controls, ensuring sensitive app data is protected without over-protecting all device traffic.
- Simplified app deployment: you can decide which apps must use the VPN, making onboarding and offboarding easier.
Industry data and user sentiment show that organizations adopting Per-App VPN report fewer user-facing performance complaints during rollout and easier policy management for remote workers. For iOS specifically, Apple’s built-in Per-App VPN support integrates tightly with MDM solutions like Intune, reducing friction for IT teams and end users.
Prerequisites and Planning
Before you start, gather and confirm these prerequisites:
- Microsoft Intune environment with the appropriate license Intune Plan 1 or higher and the ability to deploy VPN profiles.
- An iOS device enrollment program, with devices enrolled in Intune and managed via MDM.
- A VPN gateway that supports split tunneling and per-app VPN, with the correct certificates or shared secret for client authentication.
- An app list of which iOS apps should route traffic through the VPN e.g., corporate apps like Outlook, Teams, browser clients that access internal resources.
- PKI setup or certificate infrastructure if the VPN requires client certificates, or a pre-shared key PSK if your gateway uses that method.
- iOS 9.0+ devices for basic Per-App VPN; newer iOS versions provide better integration and stability.
- App IDs for the apps you want to protect, and ensure they support App VPN configuration.
Architecture Overview: How Per-App VPN Works on iOS
- The VPN workflow in iOS is handled by the Network Extension framework.
- Intune installs a VPN configuration on the device and ties it to specific apps.
- When a protected app launches and attempts to access the network, iOS routes its traffic through the VPN tunnel.
- Traffic from non-protected apps bypasses the VPN, improving performance.
- Intune can enforce conditional access policies, ensuring only compliant devices can use Per-App VPN.
Step-by-Step: Configure Per-App VPN in Intune iOS
Create the VPN profile
- Sign in to the Microsoft Endpoint Manager admin center.
- Go to Devices > iOS/iPadOS > Configuration profiles.
- Create profile > Platform: iOS/iPadOS, Profile type: VPN.
- Connection name: give it a clear name like “Corp-PerApp-VPN-Primary”.
- VPN type: IKEv2, IPSec, or your gateway’s supported protocol. Most setups use IKEv2 with certificates or EAP methods.
- Server address: enter your VPN gateway hostname or IP.
- Authentication method: certificate-based preferred; if not available, use a PSK per your gateway configuration.
- Use custom VPN payloads as needed for advanced gateway settings.
- Save and assign later.
Create the App configuration for Per-App VPN
- Still in Intune, go to Apps > App configuration policies.
- Create profile: Platform iOS/iPadOS, Profile type: VPN per app configuration.
- Name: “Per-App VPN Apps” and description for IT.
- In the per-app VPN settings, specify:
- App IDs: bundle identifiers of the apps you want to protect e.g., com.company.mail, com.company.teams.
- VPN connection name: the VPN profile name you created earlier.
- User scope optional: if you want per-user or per-device behavior.
- Enforce VPN on app traffic only when the app is running to minimize overhead when not in use.
- If your gateway uses certificate-based auth, ensure the device has the necessary certificates installed via a separate PKI profile or a trusted certificate payload.
- Save the configuration policy.
Assign and test on devices
- Assign the VPN configuration and per-app configuration policies to a device group that includes test devices.
- On a test device, enroll and verify:
- The VPN profile shows under Settings > General > VPN & Device Management.
- The protected apps show traffic routed through VPN when opened.
- Non-protected apps access the internet directly.
- Use a corporate resource test e.g., internal app server or intranet to verify traffic routing.

- App launch test: Open a protected app and confirm it uses the VPN watch for VPN status indicator.
- Resource access: Attempt to reach an internal resource from the protected app; ensure it succeeds.
- Disconnect test: Temporarily disable the VPN profile and confirm protected app traffic stops or errors gracefully.
- Battery and performance check: Ensure there’s no dramatic battery drain or lag in typical usage.

Security Considerations and Best Practices
- Always use certificate-based authentication when possible for Per-App VPN to reduce credential leakage risk.
- Keep the VPN gateway and Intune policies up to date with the latest security patches and firmware.
- Use split-tunneling judiciously: it reduces traffic on the VPN gateway but verify that sensitive traffic still routes correctly.
- Monitor for failed app VPN connections and implement fallback messaging to users explaining steps to re-establish the VPN.
- Regularly review app coverage: remove apps that no longer require VPN protection to reduce maintenance.
- Enforce device compliance policies minimum OS version, device encryption, screen lock, etc. to strengthen security posture.
Monitoring, Logging, and Troubleshooting
- Use Intune diagnostic logs and VPN gateway logs to verify configuration handshakes and tunnel status.
- Common issues and quick fixes:
- Issue: VPN never connects
- Check gateway availability, certificate validity, and network reachability from the device.
- Issue: Per-App VPN not triggering for a protected app
- Ensure the app’s bundle ID is correctly listed in the per-app policy and the app is installed on the device.
- Issue: Traffic leaks from protected apps
- Verify that the app is configured to route all traffic through the VPN, not just a subset of domains.
- Issue: VPN disconnects when device goes to sleep
- Adjust VPN keepalive or idle timeout settings on the gateway and in Intune payloads.
- Issue: VPN never connects
- Validation steps:
- Confirm VPN status in iOS settings after opening a protected app.
- Run a network capture where possible or use internal resource logs to confirm VPN-encrypted traffic.
Real-World Tips and Pitfalls to Avoid
- Start with a small pilot group of devices to validate the end-to-end flow before broad rollout.
- Document all app bundle IDs accurately; even a small typo will prevent Per-App VPN from engaging for that app.
- Align with IT and security teams on acceptable VPN protocols and certificate lifetimes to avoid a renewal crisis.
- Keep a rollback plan: if Per-App VPN causes issues, you should be able to disable the policy quickly and restore normal traffic.
- Communicate clearly with users: provide a quick-start guide and a troubleshooting contact for VPN-related problems.
- Consider user education on when VPN is active and what protection it provides to avoid confusion.
FAQ
How does Per-App VPN differ from device-wide VPN on iOS?
Per-App VPN targets only specified apps to route traffic through the VPN, while device-wide VPN tunnels all traffic from the device. Per-App VPN preserves performance and battery life while offering targeted security for apps handling sensitive data.
Do I need a certificate for every device?
Not necessarily. If your VPN gateway supports certificate-based authentication, you can issue device or user certificates via your PKI and assign them accordingly. Some setups use a shared secret PSK for both ends; however, certificate-based methods are generally more secure.
Can I use Per-App VPN with third-party VPN providers?
Yes, as long as the VPN gateway supports iOS Per-App VPN and is compatible with Intune’s per-app configuration payloads. Check vendor documentation for iOS integration specifics.
How many apps can I protect with Per-App VPN?
There’s no hard limit in Intune, but practical limits come from app management overhead and gateway capacity. Start with the most critical apps and scale up. Browsec vpn download 무료 vpn 설치와 모든 것 완벽 가이드: 빠르고 안전한 Browsec 사용법과 최신 팁
What happens if the VPN gateway is down?
Traffic from protected apps will fail to reach internal resources, and you’ll see failed connections in logs. It’s essential to have gateway failover and monitoring in place.
How do I roll back if Per-App VPN causes issues?
Disable or unassign the per-app VPN policy and the main VPN profile from the test group. Users will revert to normal traffic behavior, and IT can investigate without impacting all users.
Can I enforce VPN usage only during business hours?
Yes, you can configure conditional access and policy timers to enforce VPN connectivity during defined windows, depending on your gateway capabilities and Intune policy settings.
How do I verify that only protected apps are using the VPN?
Open a protected app, then use diagnostic tools or corporate resource logs to confirm traffic goes through the VPN tunnel. Also verify that non-protected apps access the internet directly.
What are common reasons for VPN not starting on iOS?
Common causes include misconfigured app IDs, expired certificates, incorrect server address, mismatch between VPN profile and per-app policy, or device-enrollment issues.
