What is per-app VPN in Intune for iOS?
Per-app VPN is a feature that allows specific apps on iOS devices to route their traffic through a designated VPN connection, rather than funneling all device traffic. In Intune, you create a VPN connection the actual network extension, then create a per-app VPN policy that links one or more managed apps by their bundle IDs to that VPN connection. When users launch those apps, their traffic is sent through the VPN tunnel automatically. This approach helps you protect sensitive app traffic without forcing every app on the device to use the VPN.
Per-app VPN is especially useful in scenarios like remote access to internal services, secure access for a custom corporate app, or when you want granular control over which apps use a VPN, keeping battery life and network usage in check.
Why use per-app VPN?
– Granular control: Only selected apps use the VPN, not the entire device.
– Better user experience: Apps don’t all route through the VPN, reducing latency for non-business traffic.
– Strong security posture: Traffic from critical apps is encrypted and tunneled.
– Centralized management: Policy, certificates, and app mappings are managed from Intune.
In practice, you’ll typically pair per-app VPN with a certificate-based IKEv2/IPsec connection, a trusted PKI, and a defined set of apps that actually need private-network access.
Prerequisites
– An active Microsoft Intune subscription and access to the Endpoint Manager admin center.
– An iOS/iPadOS device fleet enrolled in Intune with MDM management enabled.
– A VPN server that supports IKEv2/IPsec or equivalent compatible with Apple’s Network Extension varies by vendor.
– A PKI setup for issuing server and optional client certificates. At minimum, a trusted root/certificate authority certificate and a server certificate for the VPN.
– App IDs bundle identifiers for the apps you want to route through the VPN e.g., com.yourcompany.app.
– A reliable, tested DNS and internal routing configuration for the VPN so apps can reach internal resources securely.
– Optional but recommended: a test group of pilot users, a change-management plan, and a rollback path if something doesn’t work as expected.
Step-by-step setup in the Intune admin center
Note: The exact labels and navigation paths can change with updates, but the high-level flow remains the same.
# 1 Create the VPN connection IKEv2 in Intune
1 Sign in to the Microsoft Endpoint Manager admin center.
2 Go to Devices > Configuration profiles > Create profile.
3 Platform: iOS/iPadOS.
4 Profile type: VPN.
5 Name it something descriptive, e.g., “App VPN – IKEv2 for Internal Apps.”
6 VPN type: IKEv2 or the VPN type supported by your network.
7 Server address: enter the VPN server address.
8 Remote ID: enter your VPN remote identifier.
9 Local ID: enter your local identifier if required by your server.
10 Authentication method: Certificate-based recommended.
11 Certificate to use: select the trusted certificates you’ve uploaded to Intune this is where you attach the CA and server certificate you prepared earlier.
12 Enable VPN on demand optional: you can configure this for On-Demand behavior if your environment supports it.
13 Save and continue.
What you’re setting up here is the network extension that iOS will load for per-app VPN. You’ll reference this connection in the per-app VPN policy later.
# 2 Prepare the App IDs and certificates
– Ensure you have the app bundle IDs for all apps you want to protect with per-app VPN e.g., com.yourcompany.sales or com.yourcompany.internalapp.
– Ensure you have a trusted root certificate installed and a server certificate that your VPN uses. Upload these certificates in the Intune tenant:
– Certificates > Trusted certificates for the root CA
– Certificates > Trusted server certificate or use the certificate profile if your VPN requires client certs
# 3 Create the Per-app VPN policy
1 In the Endpoint Manager, go to Devices > Configuration profiles > Create profile.
2 Platform: iOS/iPadOS.
3 Profile type: App VPN Per-app VPN.
4 Name: e.g., “Per-App VPN – App VPN for Internal Apps.”
5 Connection name: select the VPN connection you created in Step 1.
6 App identifiers: add the bundle IDs of the apps you want to protect e.g., com.yourcompany.internalapp.
7 VPN proxy settings: configure if your VPN requires a proxy. otherwise leave default.
8 Substitute options: If you have split-tunnel requirements, enable or configure DNS/ split tunneling as supported by your VPN solution.
9 Assignments: add the user/group scope who will receive this policy e.g., All users or a specific pilot group.
10 Validate and save.
This step ties the VPN connection to the specified apps. When users launch those apps, iOS will automatically initialize the VPN tunnel for that app’s traffic.
# 4 Assign and deploy to devices
– Use the same policy to assign to the targeted user groups or devices.
– Make sure the devices are enrolled and the user groups contain the intended users e.g., a test group first, then roll out to all users.
– Monitor deployment status in the Intune console. If a deployment stalls, check for certificate issues, VPN server reachability, and the app’s bundle ID accuracy.
# 5 Install and test on a device
– On a test iOS device, install the required managed apps.
– Open one of the target apps and verify if the app VPN banner appears or if the VPN indicator shows that traffic is being tunneled.
– Use internal resources that require VPN access to confirm connectivity e.g., internal intranet site, internal API, or staging environment.
– Validate that non-protected apps traffic flows through the normal internet path no VPN.
# 6 Optional: Always-On or On-Demand behavior
– If your organization requires that the VPN is always on for the app, enable the Always On option if supported by your VPN solution and Intune policy.
– If you prefer on-demand behavior, configure the app to trigger the VPN when the app is opened and disconnect after exit, depending on your use case and user experience goals.
# 7 DNS and split-tunneling considerations
– Depending on your VPN and network design, you may want to configure split tunneling traffic for internal resources goes through VPN. public traffic goes directly to the internet.
– In iOS App VPN, DNS resolution should be configured to point to internal DNS as needed by your internal resources.
– Ensure that internal resource resolvability works when the VPN is active, and that there are no DNS leaks when the VPN is off.
# 8 Monitoring and auditing
– Use Intune’s device health and policy status dashboards to monitor deployment status.
– Check VPN server logs or Network Access Policy logs for connection attempts, certificate validation results, and tunnel status.
– Consider enabling audit logging for certificate issuance and revocation as part of your PKI management.
Testing and validation tips
– Create a small pilot group first e.g., 5–10 users to validate app behavior, VPN connectivity, and resource access.
– Validate with different network environments home Wi-Fi, corporate Wi-Fi, cellular data to ensure reliability.
– Have rollback steps ready: revoke the per-app VPN policy from the pilot group if issues occur. revert the VPN server configuration if needed.
– Document the exact bundle IDs used in the App VPN configuration so future app updates won’t break the mapping.
Common pitfalls and how to avoid them
– Incorrect bundle identifiers: The App VPN policy won’t match if the bundle ID is wrong. Double-check for typos, case sensitivity, and ensure you’re using the exact App Store/enterprise distribution ID.
– Certificate issues: If the device doesn’t trust the VPN server certificate, the tunnel won’t establish. Ensure the root CA is trusted on devices and that the server certificate chains are valid.
– Mismatched server address or remote ID: If these values don’t align with the VPN server configuration, the VPN tunnel fails to authenticate.
– App not using the VPN: Verify that the app is included in the App IDs list for the per-app VPN policy.
– Insufficient permissions: Ensure the user or admin performing the configuration has the required Intune permissions to create profiles and assign them to groups.
Best practices and security considerations
– Use certificate-based authentication whenever possible for stronger security and easier certificate renewal management.
– Centralize PKI management, rotate certificates on schedule, and implement revocation procedures for compromised certificates.
– Limit per-app VPN to only those apps that truly require private network access. avoid blanket VPN coverage to reduce overhead and ensure performance.
– Maintain clear change control and testing processes for VPN configurations, especially in production environments.
– Regularly review and clean up unused app mappings and expired certificates to keep the environment tidy and secure.
– Document failure scenarios and runbook steps for quick remediation, including how to re-issue certificates if needed.
Real-world tips and scenarios
– If you’re rolling out to a mixed device fleet, start with a pilot and gradually expand. Per-app VPN is a powerful feature, but it’s not a one-size-fits-all solution—some apps may need different network routing or additional security controls.
– For developers or security teams testing new internal APIs, set up a dedicated VPN connection alias for testing to avoid impacting production resources.
– When you update app bundles or move the app to a new bundle ID, remember to update the App VPN mappings accordingly in Intune to avoid traffic routing issues.
– If you rely on split tunneling, verify that the DNS and internal resource access paths are reachable through the VPN and don’t cause name resolution issues for internal domains.
Performance considerations
– App VPN traffic uses a VPN tunnel on iOS devices, which can impact battery life and latency. Plan a pilot to measure the impact on both users and endpoints.
– Ensure VPN servers have appropriate capacity and redundancy to handle expected app traffic during peak times.
– Monitor VPN session durations and auto-termination settings to balance security with user experience.
How to maintain and evolve your per-app VPN deployment
– Regularly validate app mappings for new app versions and new bundle IDs.
– Reassess certificates and PKI policies on a scheduled basis to maintain trust and security.
– Keep an eye on iOS updates that affect per-app VPN behavior or network extension capabilities and test accordingly before broad rollout.
– Document changes, gather user feedback, and adjust your deployment plan to minimize disruption.
Real-world example walkthrough
– Company A has three internal apps that require access to a private intranet. They set up an IKEv2 VPN with certificate-based authentication and created a per-app VPN policy mapping app bundle IDs for those three apps. They rolled this out gradually via Intune to a pilot group, validated internal resource access, and then expanded to the entire organization. They also implemented split tunneling and DNS configuration to ensure internal names resolve correctly while external traffic uses the users’ internet connections.
Common questions and troubleshooting shortcuts
– Do I need a rooted device or jailbreak to use per-app VPN? No. Per-app VPN uses iOS Network Extension and is managed via MDM without device jailbreaking.
– Can I use per-app VPN with all apps? Only the apps you explicitly add to the App IDs list will route their traffic through the VPN. Others will use the regular network path.
– What if the VPN connection doesn’t establish? Check the server address, remote/local IDs, and the certificate trust chain. Verify that the VPN server supports IKEv2 and that the certificate is valid and not expired.
– How do I verify that traffic is going through the VPN? Use internal resources that require VPN access and check the public IP from the app or use a network capture tool to confirm traffic is leaving through the VPN tunnel.
– Can I enforce Always On for per-app VPN? If supported by your VPN solution and Intune’s per-app VPN profile, you can configure an Always On setting to maintain a persistent tunnel for the apps.
– How do I test from outside the corporate network? Use cellular data or a home Wi-Fi network. verify that the app connects to internal resources only when the VPN is active.
– What is the role of DNS in per-app VPN? DNS should resolve internal resources over the VPN as needed. You may configure internal DNS in your VPN profile to ensure seamless resource reachability.
– How do I manage VPN certificates? Issue server certificates from a trusted CA, distribute them via Intune, and renew before expiry. Revoke certificates if compromised and ensure revocation lists are up to date.
– Can per-app VPN be used with other security tools? Yes, you can combine App VPN with conditional access, device compliance policies, and additional threat protection as part of a layered security approach.
– How do I monitor per-app VPN health? Use Intune reporting, VPN server logs, and device-level status indicators. Look for failed sessions, certificate errors, and misconfigurations in the App VPN policy.
– What about app updates breaking VPN mappings? Always verify the bundle IDs after app updates. If needed, update the App VPN policy with the new bundle IDs and re-deploy.
– Is per-app VPN supported across all iOS versions? Per-app VPN is supported on iOS versions that support Network Extensions and Intune’s App VPN features. Always check the latest Microsoft docs for version-specific guidance.
FAQ
Frequently Asked Questions
# 1 What exactly is “per-app VPN” in Intune for iOS?
Per-app VPN is a feature that lets you route traffic from specific managed apps through a dedicated VPN connection, while other apps on the device use the normal internet path. Intune coordinates the VPN connection and app mappings, so only the selected apps get the secure tunnel.
# 2 Which VPN types work with iOS App VPN in Intune?
IKEv2/IPsec is the most commonly used and broadly supported option. You can configure certificate-based authentication and trusted certificates to establish a secure tunnel. Some VPN vendors provide alternative configurations. ensure compatibility with Apple Network Extension requirements.
# 3 How do I add apps to the per-app VPN policy?
Add the app’s bundle identifier for example, com.yourcompany.app to the App IDs list in the per-app VPN policy. Only apps in this list will have their traffic tunneled through the VPN.
# 4 Do users need to approve the VPN connection on their device?
No. With Intune-managed per-app VPN, the VPN connection is configured and controlled by the MDM, and the user’s interaction is typically minimal beyond launching the app. Depending on the policy, you may enable On-Demand behavior.
# 5 Can I enforce Always On for per-app VPN?
Yes, if your VPN solution and Intune support the Always On option for App VPN. Always On means the VPN tunnel attempts to stay active, subject to device conditions and policy configurations.

Typically a trusted root CA certificate for server identity validation and a server certificate for server identity. If client certificates are required, you’ll issue and deploy them as part of the VPN configuration.
# 8 How is DNS handled with per-app VPN?
DNS should resolve internal resources over the VPN as needed. You may configure internal DNS servers within the VPN profile to ensure proper name resolution when the tunnel is active.
# 9 How do I monitor per-app VPN performance and status?
Monitor via Intune device health and profile deployment status, check VPN server logs for authentication and tunnel status, and use app-specific diagnostics to verify traffic routing.
# 10 What should I do if an app’s VPN mapping breaks after an update?
Verify the app’s bundle ID after the update, reconfigure the App VPN policy if necessary, and redeploy to affected devices. Keep a changelog for app updates and the corresponding VPN mappings.
# 11 Can per-app VPN be combined with other access controls?
Absolutely. Pair app VPN with device compliance policies, conditional access, and other security controls to create a strong, layered security posture while preserving user experience.
# 12 How often should I rotate VPN certificates and review mappings?
Rotate certificates on a regular schedule e.g., annually or when certificates approach expiry and review App ID mappings whenever you push app updates or deploy new internal resources. Regular reviews help prevent outages and maintain security.
If you’re ready to implement this, start with the prerequisites certificate authority, VPN server compatibility with iOS, and accurate app bundle IDs, then follow the step-by-step setup in Intune. Take it slow with a pilot group, gather feedback, and gradually scale. App VPN is a powerful tool when you want precise control over which apps use a VPN, while keeping the rest of the user experience smooth and fast.
