What is Always On VPN and why it matters
Always On VPN AOVPN is a deployment model that ensures devices connect to a corporate or private VPN as soon as they boot or join the network, and stay connected with minimal user intervention. It’s different from consumer VPN apps that users start manually. For organizations, AOVPN helps enforce consistent security, enforce device trust, and reduce the risk of sensitive data exposure when employees work remotely or on public networks.
Key benefits:
- Automatic, persistent VPN connections for improved data protection
- Centralized policy enforcement encryption standards, authentication methods, DNS safety
- Better control over split tunneling vs. full tunneling
- Easier troubleshooting with centralized monitoring and logging
If your environment is Windows-centric which is common in many businesses, AOVPN is typically built around IKEv2 or SSTP protocols with certificate-based authentication, often paired with an on-premises RRAS server or a cloud gateway like Azure VPN Gateway. This combination helps ensure devices automatically connect to the VPN, even after restarts, and stay connected until explicitly disconnected.
Prerequisites: what you need before you begin
Before you start, inventory these items:
- A VPN server that supports Always On VPN Windows RRAS on a server, or a cloud-based gateway such as Azure VPN Gateway with a compatible configuration
- A Public Key Infrastructure PKI with certificates for devices machine certificates and optionally users
- A management plane for deployment Group Policy for Windows domain, or Microsoft Intune for modern management
- Client devices running Windows 11 or Windows 10/11 with compatible features
- Administrative access on the VPN server and the client endpoints
- DNS and network routes configured so traffic destined for corporate resources is properly routed through the VPN
Optional but recommended: Edgerouter x vpn server setup guide for OpenVPN WireGuard IPsec and EdgeRouter configurations
- A DNS split-horizon plan to avoid leaking internal names
- A robust kill-switch policy to prevent traffic when the VPN is down
- Regular certificate renewal workflows to keep devices trusted
Step-by-step: enabling Always On VPN on Windows 11
Note: Most organizations deploy AOVPN with a combination of server-side configuration and a client-profile distribution mechanism Group Policy, Intune, or PowerShell scripts. Here’s a practical path you can adapt.
Step 1: Prepare the VPN server RRAS or cloud gateway
- Install and configure the VPN server role RRAS on Windows Server or set up a compatible cloud gateway Azure VPN Gateway, for example.
- Choose the VPN protocol: IKEv2 is common for AOVPN due to strong performance and native support. SSTP is another option if you need TCP-based reliability.
- Configure authentication:
- Use certificate-based authentication machine certificates for devices. optional user certificates for users
- If you rely on RADIUS, ensure it’s reachable and properly configured
- Create and publish the VPN client access policy, including:
- The VPN server address publicly reachable
- The necessary authentication method
- The DNS settings your clients should use when connected
- Ensure proper network routing:
- Decide on split tunneling vs. full tunneling
- Add appropriate routes so corporate resources are reachable through the VPN
- Export or prepare a VPN profile for clients this will be consumed by the deployment channel
Step 2: Prepare client devices Windows 11
- Ensure devices are joined to a domain or managed by Intune for easier policy deployment.
- Install any required root certificates and machine certificates on each device or set up auto-enrollment for PKI.
- Configure firewall and security rules to allow VPN traffic IKEv2, ESP, and management ports.
Step 3: Configure the Always On VPN profile on Windows via Intune or Group Policy
- If you’re using Intune modern management:
- Create a VPN profile with:
- Connection name friendly name
- Server address public VPN endpoint
- VPN type: IKEv2
- Authentication method: Machine certificate
- Automatic trigger: Include a setting for “Always On” so the VPN starts automatically on boot
- DNS and split tunneling preferences
- Deploy the profile to the target device group
- Create a VPN profile with:
- If you’re using Group Policy legacy approach:
- Create a VPN connection profile using Windows built-in VPN features
- Enable the “Always On VPN” behavior via policy this typically ties the VPN connection to device startup and user logon
- Ensure the policy is linked to the correct OU and applied to the target machines
- Validate: Reboot a test device and verify that the VPN connects automatically without user intervention
Step 4: Validate certificate trust and connectivity
- Confirm that device certificates are installed and trusted by the client devices
- Check that the VPN connection negotiates a secure tunnel IKEv2/IPsec or SSTP and assigns the correct route tables
- Verify that corporate resources internal websites, file shares, or apps resolve and are reachable only through the VPN when connected
- Test disconnection and automatic reconnect behavior to ensure the “Always On” requirement holds
Step 5: Monitor, adjust, and maintain
- Use Windows Event Viewer or your SIEM to monitor VPN events, connection drops, and authentication issues
- Review certificate expiration dates and renewal workflows
- Periodically test failover to the primary gateway and any backup paths to ensure resilience
- Update client profiles if server endpoints or policies change
Optional: Always On VPN on other platforms
- macOS: Apple’s built-in VPN client supports IKEv2 and certificate-based authentication, but “Always On” behavior tends to be achieved through configuration profiles deployed via MDM like Intune and a macOS-specific VPN plugin if your environment requires it.
- iOS: iOS supports IKEv2 VPN with per-app and system-wide configuration. True “Always On” behavior can be achieved via managed configurations, but you’ll often see this implemented as an always-on global VPN toggle in device management.
- Android: Android supports built-in VPNs and IKEv2 in many versions. For true Always On behavior, use a device policy controller DPC via Enterprise Mobility Management EMM with a VPN profile set to auto-connect on startup.
If you’re evaluating cross-platform needs, this is where a mature EMM/MDM strategy shines: it helps you deliver consistent VPN profiles across Windows, macOS, iOS, and Android with minimal friction for end users.
Security best practices for Always On VPN
- Prefer certificate-based authentication over user/password combos to reduce credential theft risk.
- Use strong encryption suites AES-256 and modern IKEv2 ciphers and keep your crypto policies up to date.
- Enable a robust kill switch so leak-prone traffic can’t bypass the VPN if the tunnel drops.
- Implement split tunneling carefully:
- If you only need access to internal resources, consider forced tunneling to reduce exposure.
- If you rely on local internet access for non-corporate traffic, configure split tunneling thoughtfully. ensure critical data still traverses the VPN.
- Regularly rotate certificates and enforce automatic renewal where possible.
- Enable telemetry and logging to monitor connection health and security events without compromising privacy.
- Ensure DNS is tunneled through the VPN to prevent DNS leaks, and consider DNSSEC or trusted internal DNS resolvers.
Performance and reliability tips
- Run performance tests to understand how the VPN affects throughput and latency, especially for remote workers with satellite or mobile connections.
- Consider load balancing across multiple VPN gateways to avoid a single point of failure.
- Use persistent routing rules to minimize reconnection times after a network hiccup.
- Keep client devices updated with the latest OS and VPN client components to benefit from performance improvements and security fixes.
- If you see frequent disconnects, review certificate validity, server load, and the quality of the public internet path between the client and gateway.
Troubleshooting common issues
- VPN won’t auto-connect after reboot: verify the Intune/Group Policy deployment and ensure the Always On flag is enabled in the profile.
- Certificate errors on clients: check the certificate chain, trust anchors, and auto-enrollment status.
- DNS resolution failing when connected: confirm that DNS settings are pushed through the VPN and that internal resolvers are reachable via the tunnel.
- High latency or dropped connections: test alternative gateways, review MTU settings, and ensure there’s no firewall blocking ESP/IPSec traffic.
- Clients show connected but can’t reach internal resources: verify routes, split tunneling rules, and resource firewall rules on the server side.
- Issues after roaming between networks: ensure the VPN client supports seamless handoff and that the gateway remains reachable across networks.
Real-world considerations and use cases
- Remote-work adoption: AOVPN helps ensure that every remote worker has a secure, continuous path to company resources, reducing risk from public Wi-Fi or shared networks.
- BYOD environments: Centralized management reduces the amount of friction users face while keeping corporate data protected.
- Compliance-driven setups: If your industry requires strict data protection and auditability, AOVPN helps enforce consistent security controls and logging.
Costs, ROI, and planning
- Initial setup cost includes server/gateway licensing, PKI management, and potentially an MDM/EMM solution.
- Ongoing costs involve certificate renewal, gateway maintenance, and monitoring tools.
- ROI comes from reduced data exposure risk, easier remote work logistics, and improved policy enforcement across devices.
