What is Always On VPN?

Always On VPN is a feature that ensures your VPN connection is maintained automatically — even after a reboot, network change, or loss of connectivity. Unlike traditional VPNs, which need to be manually started and stopped, Always On VPN creates a persistent, automatic tunnel between the device and your network.

This means as soon as the device connects to the internet — even before the user logs in — the VPN kicks in and routes all traffic securely.

How Does Always On VPN Work?

Always On VPN relies on device-based or user-based policies configured through MDM solutions, Group Policy, or Intune. It uses protocols like IKEv2, SSTP, or L2TP/IPsec, and leverages certificate-based or EAP authentication.

In most enterprise environments, the VPN connection is configured using Windows PowerShell scripts or Microsoft Intune, with the option to connect before sign-in, securing the device at the earliest stage of use.

Always On VPN vs Traditional VPN

While traditional VPNs serve a purpose, they rely heavily on user action and can be easily disabled or forgotten. This poses significant risks in corporate environments where compliance and data security are priorities. Always On VPN, in contrast, is configured to start automatically at boot and remains connected in the background. For a detailed breakdown of how Always On VPN improves upon traditional VPN setups, check out this expert explanation of its advantages over legacy solutions. 

This level of automation minimizes human error and ensures a higher standard of security across the board.

3. Better User Experience

There’s no need for user interaction; it just works silently in the background.

4. Granular Control

Admins can configure split tunneling, route rules, traffic filters, and more using PowerShell or Intune.

5. Improved Compliance

Always On VPN helps organizations meet strict security standards and data protection regulations.

Key Features of Always On VPN (AOVPN)

Always On VPN is a powerful, modern VPN solution designed to provide seamless, secure connectivity for devices anytime, anywhere. Its key features include:

1. Support for User and Device Tunnels:

 AOVPN supports two types of VPN tunnels — User Tunnel and Device Tunnel. The User Tunnel connects after user sign-in, providing access to user-specific resources, while the Device Tunnel connects before sign-in, allowing management and security policies to apply even when no user is logged in.

2. Integration with Modern Authentication:

 It supports native integration with Windows Hello for Business, multi-factor authentication (MFA) via Microsoft Entra ID (Azure AD), and certificate-based authentication. This provides strong, seamless security and single sign-on experiences.

3. Conditional Access and Compliance Enforcement:

AOVPN can integrate with conditional access policies that check device compliance, health status, and user identity before allowing VPN connection. This ensures that only trusted, secure devices gain access to sensitive corporate networks.

4. Advanced Traffic and Application Filtering:

 Administrators can define granular traffic filters and per-application VPN policies. This means only approved apps or specific traffic types are allowed through the VPN, reducing exposure and improving security.

5. Auto-Triggering of VPN Connections:

VPN connections can be automatically triggered by application launches, DNS name resolution, or network changes, providing a smooth user experience where VPN activates only when necessary.

6. Support for Multiple Network Protocols:

AOVPN uses modern, secure tunneling protocols like IKEv2/IPsec, with fallback to SSTP if needed, maximizing compatibility across various networks and firewalls.

7. Dual-Stack IP Support and Custom Routing:

Supports both IPv4 and IPv6 traffic, with flexible routing options such as split tunneling, forced tunneling, and exclusion routes to optimize network traffic flow and reduce unnecessary load.

8. Compatibility with Enterprise Management Tools:

AOVPN settings and profiles can be deployed and managed via Microsoft Endpoint Manager (Intune), PowerShell, Group Policy, or third-party mobile device management (MDM) tools, simplifying administration at scale.

9. High Availability and Load Balancing:

Supports network policy server (NPS) clustering, load balancing, and geographic resilience, ensuring reliable VPN access even in high-demand or geographically distributed environments.

Supported Integrations with Always On VPN

Always On VPN integrates seamlessly with both Microsoft and third-party platforms to enhance security, user experience, and IT management.

A key integration is with Windows Information Protection (WIP), which enforces network policies to control which applications can send data over the VPN. When corporate data is accessed, Always On VPN is automatically triggered—eliminating the need for manual activation and ensuring sensitive information stays protected.

Another important integration is with Windows Hello for Business, enabling passwordless, certificate-based authentication. This allows users to sign into their device and Always On VPN simultaneously, providing a smooth single sign-on (SSO) experience without needing extra credentials.

Always On VPN also supports Microsoft Entra ID (formerly Azure Active Directory) conditional access policies. This enables multi-factor authentication (MFA) and device compliance checks before a VPN connection is established. Compliance is enforced through tools like Microsoft Endpoint Manager (Intune), ensuring that only trusted, healthy devices can connect.

Additionally, Always On VPN is compatible with third-party VPN clients via Universal Windows Platform (UWP) plug-ins. It works with vendors like Pulse Secure, FortiClient, and SonicWall, allowing organizations to maintain their existing VPN infrastructure while gaining the benefits of Always On VPN’s automation, security, and flexibility.

Together, these integrations make Always On VPN a robust, enterprise-ready solution that supports secure access across diverse environments and device ecosystems.

How to Scale Always On VPN (AOVPN)

Scaling Always On VPN to support a growing number of users and devices requires a well-planned infrastructure that balances performance, reliability, and security. To start, deploying multiple VPN servers and using load balancing techniques is essential. This ensures that connection requests are evenly distributed across servers, preventing any single server from becoming a bottleneck. Network Policy Servers (NPS) can be clustered to provide fault tolerance and high availability for authentication and authorization processes, so if one server goes down, others seamlessly take over without disrupting user connectivity.

Geographic load balancing is another key strategy for scaling AOVPN, especially for organizations with a distributed workforce across different regions. By deploying VPN gateways closer to users and leveraging DNS-based traffic routing (such as Azure Traffic Manager or Global Server Load Balancing), connections are directed to the nearest, least congested VPN server, improving connection speed and reliability.

To manage the large number of devices, centralized management tools like Microsoft Endpoint Manager (Intune) or System Center Configuration Manager (SCCM) are used to deploy and update VPN profiles, certificates, and policies efficiently. This automation reduces administrative overhead and ensures consistent configurations across all endpoints.

Finally, monitoring and analytics play a crucial role in scaling Always On VPN. Using monitoring solutions, administrators can track connection performance, detect bottlenecks, and identify potential security risks in real time. This visibility allows proactive adjustments to infrastructure and policies, ensuring the VPN environment scales smoothly as demand grows without compromising user experience or security.
