Prerequisites and planning
- Prerequisites checklist:
- An active Microsoft Intune tenant with user affinity and enrollment enabled
- An Apple MDM Push Certificate APNs uploaded to Intune
- A VPN gateway that supports split-tunnel or full-tunnel and supports IKEv2/IPsec or L2TP as needed
- The VPN server certificate should be trusted by devices public CA or internal PKI
-=iOS devices running iOS 14 or later for best compatibility
- Plan your per-app VPN scope:
- Decide which apps will use the VPN e.g., Outlook, Salesforce, Dropbox
- Determine if all users or specific groups should get the policy
- Prepare app identifiers bundle IDs to map to your VPN rules
- Security considerations:
- Use MFA where possible for VPN access
- Limit VPN access to corporate IP ranges if needed
- Monitor VPN sessions and set up alerts for anomalous usage
Step-by-step: creating your per-app VPN profile in Intune
- Step 1: Create a VPN server profile
- In the Intune admin center, go to Devices > Configuration profiles > Create profile
- Platform: iOS/iPadOS
- Profile type: VPN
- Connection name: give it a clear name like “Per-App VPN – AppName to VPN”
- VPN type: IKEv2 or IPsec depending on your gateway
- Server settings: enter the gateway address, remote ID, and local ID if required
- Authentication: certificate or EAP, depending on your setup
- Use a trusted certificate for the VPN server and install the client certificate on devices if needed
- Step 2: Enable Per-App VPN
- In the same profile, enable Per-App VPN
- Add the VPN connection to be used by selected apps
- Configure App IDs bundle IDs for the apps that will route traffic through the VPN
- Step 3: Configure App-specific mapping
- Map each target app to the VPN connection you created
- You can use a single VPN profile for multiple apps or separate profiles per app if needed
- Step 4: Assign the profile to users/devices
- Choose the user or device groups that will receive the per-app VPN policy
- Ensure pilot groups include representative devices and app sets
- Step 5: Create and assign a per-app VPN policy App configuration policy
- In Intune, go to Apps > All apps > Add or use the same VPN profile
- For each app, specify the policy to use the per-app VPN profile you created
- If necessary, set a conditional access rule to enforce VPN usage for specific apps
- Step 6: Deploy and monitor
- Save and deploy the policy
- Use Intune reporting to monitor deployment status and device check-ins
- Check VPN connection status via the App provisioning logs on each device
Key settings and options to consider
- VPN type nuances:
- IKEv2 vs IPsec: IKEv2 is commonly easier to configure with modern gateways; IPsec may require more PKI work
- Split-tunnel vs full-tunnel:
- Split-tunnel lets only app traffic go through VPN; non-app traffic uses normal network
- Full-tunnel routes all traffic through VPN; higher security but potential performance impact
- Certificate management:
- Client certificates simplify user experience; consider automatic certificate enrollment via Intune
- Auto-reconnect and idle timeout:
- Enable auto-reconnect to maintain VPN sessions during brief network changes
- Set reasonable idle timeouts to preserve battery and resources
- Logging and troubleshooting:
- Enable VPN logs on devices for troubleshooting
- Use VPN server logs to correlate user sessions and diagnose failures
- App whitelist/blacklist:
- Maintain a dynamic list of apps that should or should not use VPN in your MDM solution
- User experience:
- Ensure users understand which apps are VPN-protected and what features may be affected by VPN
Validation and testing
- Quick test flow:
- Enroll a test device
- Install a test app mapped to VPN
- Verify that the app traffic is going through the VPN tunnel use app-specific checks, ISP-based tests, or VPN server logs
- Check app functionality when VPN is on vs off
- Common issues and fixes:
- App not routing: confirm bundle ID matches exactly; ensure VPN profile is assigned
- VPN disconnects: check gateway compatibility, certificate validity, and network reachability
- Slow performance: inspect VPN server load, MTU issues, DNS resolution inside VPN
- Performance benchmarks:
- Expect minor latency increase due to VPN overhead; document baseline before deployment
- Monitor VPN server CPU, memory, and concurrent connections for capacity planning
Advanced topics and best practices
- Hybrid environments:
- For mixed OS fleets, consider separate VPN profiles for iOS and Android with consistent naming
- Zero Trust alignment:
- Pair per-app VPN with conditional access policies to ensure only compliant devices access sensitive apps
- App pre-warming and standby:
- If your apps rely on long-lived sessions, configure keep-alive settings and re-authentication flows
- User communication:
- Provide clear in-app notices or quick guides about VPN behavior
- Prepare a rollback plan if issues arise during deployment
- Compliance and auditing:
- Maintain a change log of VPN profile updates and app mappings
- Use Intune audit logs to demonstrate policy enforcement during audits
Real-world tips and common pitfalls
- Tip: Name your VPN profiles and app mappings clearly to avoid confusion in large environments
- Tip: Start with a small pilot group before rolling out to the entire organization
- Pitfall: Overlapping VPN rules—avoid assigning multiple VPN profiles to the same app
- Pitfall: Missing keystore or invalid certificates—validate certificate issuance and trust chains
- Tip: Use the Intune monitoring dashboard to quickly identify devices that are not receiving the policy
- Tip: Keep VPN gateway firmware and software up to date to avoid compatibility issues with iOS updates
Metrics to track after deployment
- Deployment success rate by device group
- App-specific VPN usage percentage
- VPN tunnel uptime per device
- Average time to first app connection after enrollment
- User feedback and common support tickets related to VPN
Troubleshooting cheat sheet
- Device not receiving the VPN profile:
- Check enrollment status and MDM authority, verify APNs certificate, refresh policy
- App traffic not routing through VPN:
- Verify app mapping to VPN, confirm the VPN is active when app runs, look at server-side logs for the session
- VPN disconnects during use:
- Check gateway health, certificate validity, and network reachability; consider enabling auto-reconnect
- Performance issues:
- Monitor VPN server load, check MTU, review DNS resolution inside the tunnel
- Authentication failures:
- Confirm client certificates or credentials, verify certificate trust, and check for expired certificates
Security considerations
- Ensure least privilege for VPN access and limit to necessary user groups
- Use strong encryption and up-to-date VPN protocols
- Regularly rotate certificates and update gateway configs
- Enable auditing and alerting for anomalous VPN activity
