Why use Per-App VPN on iOS with Intune?
Per-app VPN lets you control which apps send their traffic through a VPN tunnel, improving security without slowing down every app on the device. For organizations with sensitive data in specific apps like corporate email clients, file storage, or internal portals, this is a powerful way to enforce encryption and secure access. On iOS, Apple requires developers to implement per-app VPN using the NetworkExtension framework, and Intune provides a seamless way to deploy and manage those configurations.
- Benefit #1: App-level security without blanket device VPN
- Benefit #2: Flexible deployment across multiple apps and groups
- Benefit #3: Simplified user experience with automatic VPN when launching protected apps
- Benefit #4: Strong integration with Azure AD for access control
Data point: In 2023, a majority of mid-to-large enterprises adopted some form of per-app VPN strategy, with iOS devices remaining a leading target for secure app traffic routing.
Prerequisites and planning
Before you start, gather these essentials:
- Azure Active Directory Azure AD tenant with global administrator or Intune administrator rights.
- An Intune license Microsoft Intune or Microsoft 365 Business/Education with Intune.
- An iOS device fleet enrolled in Intune either via Automated Device Enrollment ADE or MDM enrollment.
- VPN provider or VPN server that supports per-app VPN on iOS and a compatible VPN profile IKEv2, L2TP over IPSec, or modern SSL VPN depending on your setup.
- PKI certificates or a trusted root certificate for your VPN, if required by the VPN server.
Step-by-step checklist:
- Define the apps that should use VPN
- Ensure VPN server and network are prepared
- Prepare the VPN client configuration template
- Create the per-app VPN profile in Intune
- Assign the profile to the right user/device groups and map to apps
- Test and validate behavior on iOS devices
- Monitor, audit, and adjust
Tip: If you’re new to PKI, you’ll want to have a certificate authority in place for VPN authentication, or use certificate-based VPN credentials where supported. Nordvpn apk file the full guide to downloading and installing on android
How Intune per-app VPN works on iOS
- The per-app VPN feature uses iOS’s NetworkExtension framework to create a VPN tunnel on a per-app basis.
- Each app that’s registered for the per-app VPN will automatically trigger the VPN connection when the app launches and will disconnect when the app closes or after a defined idle period.
- Intune stores the VPN configuration the “NetworkExtension” payload and pushes it to devices. The user doesn’t need to configure the VPN manually in most cases.
Important notes:
- Per-app VPN in iOS is VPN-on-demand for the selected apps; the device itself may still have a separate, default VPN if configured.
- Split tunneling configuration is typically determined by the VPN server and the app’s network rules; you can influence it via VPN policies and server-side routing.
- Not all VPN servers or providers support every iOS NetworkExtension requirement; confirm compatibility before deployment.
Planning the app mapping and groups
The key to success is mapping apps to a per-app VPN policy so only intended apps use the tunnel. A few practical patterns:
- Group apps by functional area: Email, file sharing, internal portal, and developer tools.
- Create security groups in Azure AD for app-based access control and map them to Intune per-app VPN assignments.
- Prepare a test group with a subset of devices to validate before broader rollout.
Format ideas:
- App groups: InternalApps, SensitiveApps, PublicApps
- VPN mapping: App1.com, App2.net, CorporatePortal.iac
Creating the per-app VPN in Intune step-by-step
- Sign in to Microsoft Intune admin center
- Go to Devices > Configuration profiles
- Create profile
- Platform: iOS/iPadOS
- Profile type: VPN
- Connection name:
- VPN type: IKEv2 or Certificate-based VPN depending on your setup
- Server: VPN server address
- Authentication: EAP or certificate-based, as required
- Remote ID: as configured on VPN server
- Local ID: optional, depending on server
- Account name: user/account if needed
- Per-App VPN settings
- Enable Per-App VPN
- App identifier: specify the app bundle IDs com.company.app1, com.company.app2
- App rule: choose whether to require VPN for all instances of the app or only when certain domains are accessed
- Authentication and certificates
- If using certificate-based VPN, upload or reference a trusted certificate profile
- If using username/password, configure credentials or use certificate-based for automation
- Assignments
- Assign the profile to user groups or device groups
- Ensure the app identifiers included match the apps you want to route through VPN
- Save and publish
Tips:
- Use App IDs that are stable and documented by the app developers.
- For iOS devices, ensure the VPN connection is allowed to run in the background by configuring appropriate device restrictions if needed.
Configuring App-specific VPN rules and behavior
- App-level routing: Use domain-based rules to control which traffic goes through VPN and which goes direct. For example, corporate SaaS endpoints should route via VPN, while public endpoints may not.
- Idle timeout and disconnect behavior: Set a reasonable idle timeout to conserve device battery.
- Reconnect behavior: Decide if the VPN should auto-reconnect on short network drops.

- Start with a conservative rule set and expand as you validate stability and user experience.
- Maintain a change log for VPN profile updates so IT can track changes and user impact.
PKI and certificate management for iOS per-app VPN
- Certificate-based authentication is common for enterprise VPNs. If you’re using certificate-based VPN, prepare:
- A PKI with a trusted root certificate in the iOS devices
- Client certificates issued to user devices
- A certificate revocation list CRL or OCSP in case of revocation
- Intune supports distributing trusted root certificates and client certificates via the Certificate Profiles and SCEP/PKCS certificates.
Security tip: Always revoke or reissue certificates when a device is lost or when an employee leaves the organization.
User experience and onboarding
- Once the per-app VPN profile is deployed and assigned, end users may see a VPN status indicator in iOS. The VPN connection typically starts automatically when one of the mapped apps launches.
- If your users install a new app that should be protected, you can add the app’s bundle ID to the policy and re-deploy to include the new app in the per-app VPN mapping.
- Communicate expectations to users: which apps will trigger VPN, what to do if the VPN fails, and how long it may take to reconnect after a network change.
Persona tips:
- For frontline workers: Keep the VPN profile lightweight and avoid forcing VPN for non-work apps to preserve battery life and user experience.
- For developers: Consider a test group of devices with a few apps before mass rollout to catch issues early.
Monitoring, reporting, and troubleshooting
Monitoring:
- Use Intune reporting to track deployment status, device enrollment, and policy application.
- Check VPN device logs for per-app VPN events:
- App launched -> VPN started
- App closed or disconnect -> VPN disconnect
- Reconnects after network changes
Troubleshooting steps:
- If a mapped app fails to route traffic through VPN, verify:
- The app’s bundle ID is correctly added to the per-app VPN policy
- The VPN server is reachable and accepts the client certificate if certificate-based
- The device has a valid certificate and the root certificate is trusted
- The app doesn’t have a conflicting network extension or another VPN in use
- Common user-facing issues include delayed VPN startup or battery impact. Review idle timeout settings and server load.
Data point: In practice, most VPN issues on iOS devices come from misconfigured App IDs or expired client certificates rather than client device problems. Como desativar vpn ou proxy no windows 10 passo a passo: Guia completo, dicas rápidas e recursos úteis
Security considerations
- Ensure per-app VPN does not bypass corporate policies and that only approved apps route via VPN.
- Keep the VPN server up to date and monitor for anomalous connections.
- Regularly audit app mappings and group memberships to ensure only authorized users have access.
Performance considerations
- VPN overhead can impact latency. Optimize by:
- Selecting a performant VPN protocol IKEv2 or modern alternatives
- Reducing unnecessary app routes through VPN minimize the number of apps forced to use the VPN
- Ensuring VPN servers have sufficient capacity and load balancing
Real-world example: Medium enterprise deployment
- Company X deployed per-app VPN for iOS to protect email and file-sharing apps.
- They grouped apps into CriticalApps Email, SharePoint, Intranet, and NonCriticalApps Public portals.
- Implemented certificate-based VPN with a short idle timeout of 5 minutes.
- After rollout, users reported seamless experience with automatic VPN when opening protected apps and no impact on non-protected apps.
Advanced topics
- Conditional access integration: require users to be compliant or use MFA to access VPN-protected apps.
- Network segmentation: use split tunnel to limit traffic to corporate resources.
- Multi-tenant considerations: for managed service providers, consider per-tenant profiles and careful app mapping.
- Compliance reporting: track access to sensitive apps and generate usage reports.
Troubleshooting quick reference cheat sheet
- App IDs missing from VPN policy? Add them and re-assign.
- VPN not starting after app launch? Check VPN server status and device certificate validity.
- Certificate issue on iOS? Ensure trusted root is installed and client cert is valid.
- App traffic not routing through VPN? Verify domain routing rules and server-side policy.
- Device not receiving policy? Confirm enrollment state and license status.
Best practices checklist
- Define a clear set of protected apps and business justification.
- Use groups to simplify assignments and updates.
- Prefer certificate-based VPN for automated provisioning.
- Enable auto-reconnect with sensible retry logic.
- Regularly review and refresh app mappings and certificates.
- Test with a pilot group before organization-wide rollout.
