What is Always On VPN and why it matters
Always On VPN AOVPN is a connection model designed for reliable, seamless enterprise remote access. Instead of waiting for a user to manually start a VPN session, the client connects automatically as soon as the device boots or gains network connectivity. That means:
- No more forgotten VPN connections after login or wake from sleep
- Consistent security posture, with traffic tunneled through the corporate network by default
- Simplified policy enforcement, since the VPN is persistent and managed centrally
- Better protection against data leaks, hostile networks, and man-in-the-middle threats
In practice, AOVPN is most commonly implemented in Windows environments via RRAS or cloud-based gateways but the concept translates to macOS, iOS, and Android through platform-specific profiles and On Demand rules. For organizations with large remote workforces or distributed campuses, AOVPN reduces manual steps for end users and lowers the risk of unsecured connections slipping through the cracks.
From a security perspective, Always On VPN pairs well with certificate-based authentication, modern encryption IKEv2 or OpenVPN with robust ciphers, MFA, device compliance checks, and strong DNS protections. It’s not a silver bullet, but when designed well, it reduces attack surface and improves visibility for IT teams.
As remote work continues to be the norm, more IT teams are leaning into AOVPN to deliver a consistent, reliable, and auditable VPN experience. The technology isn’t “one-click magic” for every device, but when planned and rolled out with proper policies, it can transform how securely remote employees access internal resources.

How to enable Always On VPN on Windows 11/10
Windows remains the most common platform for enterprise Always On VPN deployments. Here’s a practical, high-level path you can follow, with emphasis on what to configure and how to test.
- Step 1: Prepare the VPN server
- Install and configure VPN gateway services IKEv2/SSTP are common choices.
- Publish the necessary root and client certificates if you’re using certificate-based auth.
- Create a VPN profile on the gateway that uses persistent connection logic and a forced tunnel if your policy requires all traffic to traverse the corporate network.
- Step 2: Create a VPN profile on the client
- Go to Settings > Network & Internet > VPN > Add a VPN connection.
- Choose Windows built-in as the VPN provider.
- Fill in server address, VPN type IKEv2 recommended for compatibility and security, and authentication method certificate-based or EAP-TLS.
- Name the connection clearly e.g., “CorpVPN Always On”.
- Step 3: Enable Always On at scale
- If you’re using Intune or another MDM, push a device policy that sets the VPN as Always On and configures automatic reconnect, per-user or per-device, depending on your governance model.
- Alternatively, use PowerShell on the client to enable Always On for the profile, e.g., Set-VpnConnection -Name “CorpVPN Always On” -AlwaysOn $true -Force. Check your environment’s exact syntax and test in a lab first.
- Ensure “Force tunnel” or equivalent setting is aligned with your policy do you want all traffic to go through VPN or only corporate resources?.
- Step 4: Enforce and monitor
- Use your MDM’s compliance policies to ensure devices stay enrolled and VPN connections are active when connected to the internet.
- Set up logging and monitoring for VPN sessions connection duration, re-authentications, and failures.
- Step 5: Test thoroughly
- Reboot a test device and confirm VPN connects automatically.
- Disconnect and re-connect networks Wi-Fi vs. cellular to verify auto-connect behavior is consistent.
- Run leak tests to ensure DNS and IP do not leak when the VPN is active and when it drops.
- Security notes
- Prefer certificate-based authentication for the strongest posture.
- Pair with MFA where possible.
- Ensure endpoint security software is up to date and configured to cooperate with VPN profiles.
- Consider a kill switch so that if the VPN tunnel drops, traffic doesn’t route unprotected.
Tips:
- Keep a lab separate from production to validate changes before rolling out to all users.
- Document user experiences and common issues for the help desk.
- Expect some users to encounter certificate enrollment delays. have a fallback, like a manual connect option, while the rollout completes.
If you’re using a Microsoft-based stack, you’ll often find a tight integration path with Intune policies and Windows Server’s RRAS. The exact steps can vary depending on your VPN gateway and certificate setup, so always cross-check with the latest Microsoft docs and your gateway vendor’s guidance.
How to enable Always On VPN on macOS
macOS support for Always On VPN is typically achieved via enterprise profiles IKEv2 or another compatible protocol and On Demand rules, often deployed through MDM. Browsec vpn – free and unlimited vpn for privacy, streaming, and secure browsing: in-depth guide 2025
- Profile-based deployment
- Create a VPN profile with IKEv2 or your chosen protocol and attach the certificate or credentials needed for authentication.
- Include an On Demand rule so the VPN connects automatically when network activity demands it and disconnects when appropriate.
- On Demand rules
- On macOS, On Demand rules let you specify the apps or network conditions that trigger a VPN connection. For Always On-like behavior, you’ll want a default On Demand policy that connects when any non-corporate traffic is detected and maintains the tunnel as long as a network is available.
- Deployment
- Push the profile via MDM JAMF or another solution to all corporate Macs.
- Verify that the profile remains active and that re-enrollment happens when devices are wiped or reset.
- Testing and troubleshooting
- Ensure the VPN reconnects after sleep or wake and after switching between networks Wi-Fi to Ethernet, for example.
- Check for DNS resolution through the VPN and prevent leaks by confirming DNS queries are routed via the corporate resolver.
- Security considerations
- Enable certificate validation and pinning where possible.
- Ensure the device complies with security policies before the profile is installed.
- Pull in MFA if your VPN supports it to strengthen authentication.
Note: macOS environments often rely on profile-based configurations rather than a single toggle labeled “Always On,” but the end result is the same: automatic, persistent VPN connectivity with centralized management.
How to enable Always On VPN on iOS iPhone and iPad
iOS devices are commonly managed via MDM in enterprise deployments. Here’s a practical workflow:
- Profile creation
- Build a VPN profile IKEv2 or IKEv2 with certificate-based authentication is common with On Demand rules.
- Include required server URIs, authentication methods, and identity certificates if you’re using a PKI.
- Use On Demand to ensure the VPN connects automatically when the device is used and restricts traffic outside the VPN when the policy requires it.
- Push the VPN profile to iOS devices via your MDM.
- User experience and testing
- Verify that the VPN connects automatically after device boot or wake and remains connected across app launches and network changes.
- Check that DNS is resolved through the VPN and that corporate resources are accessible.
- Require device enrollment and compliance checks.
- Enforce certificate rotation and revocation as part of your PKI policy.
- Use MFA for VPN authentication if supported.
On iOS, the On Demand policy is the closest analog to the Windows “Always On” concept. Clear communication to users is essential so they understand why the VPN is connected automatically and what to do if it doesn’t.
How to enable Always On VPN on Android
Android devices offer a straightforward path to Always On VPN in recent versions, with settings that make auto-connecting VPNs practical.
- Locate Always-on VPN
- Go to Settings > Network & Internet > VPN and select your corporate VPN profile.
- Turn on Always-on VPN and optionally Block connections without VPN depending on the Android version and vendor customization.
- Management and deployment
- Push VPN profiles via an EMM/MDM Intune, VMware Workspace ONE, AirWatch, etc. so devices receive the right server info and authentication method.
- Testing
- Reboot the device and verify the VPN starts automatically with a connection to the corporate gateway.
- Switch networks cellular to Wi-Fi to ensure the tunnel stays up or reconnects cleanly.
- Use certificate-based authentication or strong MFA where supported.
- Ensure device compliance with security policies and keep the OS updated.
- Consider a kill switch or equivalent mechanism to prevent data leakage if the VPN fails.
Android’s Always On VPN feature is particularly handy for devices that move around a lot or operate in environments with fluctuating network connectivity. How to connect edge vpn
Testing, verification, and troubleshooting
A solid testing plan helps ensure your Always On VPN actually delivers the protection and reliability you’re aiming for.
- Verify auto-connect
- Reboot a test device, disconnect the network, and ensure the VPN reconnects automatically on startup and after network changes.
- DNS and IP leakage tests
- Use dnsleaktest.com, ipleak.net, or similar tools to confirm that DNS requests are routed through the VPN and that there’s no IP leakage when the tunnel is active or down.
- Check for split tunneling vs. forced tunnel
- If your policy requires a forced tunnel, ensure corporate traffic is always funneled through the VPN, while non-corporate traffic should not bypass it.
- Performance checks
- Test latency and throughput to critical internal resources from various geographies to ensure acceptable performance under VPN load.
- Kill switch verification
- Temporarily drop the VPN and verify that traffic doesn’t route outside the tunnel unless you’ve explicitly allowed it.
- Endpoint health
- Confirm endpoint security posture antivirus, firewall, OS updates to prevent security gaps that undermined the VPN’s protections.
Documentation and runbooks are your friends here. Keep a step-by-step troubleshooting guide handy for the help desk and a quick-change policy for IT admins.
Best practices for a successful Always On VPN deployment
- Use certificate-based authentication whenever possible for stronger security and easier management at scale.
- Pair VPN with MFA to reduce the risk of credential theft compromising access.
- Enforce device compliance OS patches, security software, encrypted disks to prevent vulnerable endpoints from becoming entry points.
- Consider a two-layer protection approach: Always On VPN for secure access, plus a robust endpoint protection suite for malware, phishing, and zero-day threats.
- Plan for disaster recovery and failover. Ensure you have alternate gateways or backup configurations in case your primary VPN gateway becomes unavailable.
- Maintain clear user communications: provide onboarding guides, troubleshooting steps, and a support contact flow.
- Regularly review and rotate certificates, update VPN profiles, and test policy changes in a lab before rolling out to production.
- Monitor VPN usage and security events. Dashboards that show connection counts, failed authentications, and tunnel health help you spot and fix issues quickly.
- Keep TLS/DTLS and encryption standards current. As threats evolve, so should your cryptographic settings.
Frequently Asked Questions
