User Authentication

OpenVPN offers a robust authentication system. The built-in system comes with web-based management, allowing for easy user setup and monitoring.

For organizations that already use external authentication systems, OpenVPN supports PAM, LDAP, RADIUS, and SAML. Additionally, if you need to implement specialized authentication logic, you can use Python for custom programming.

Professional Support

OpenVPN Inc. backs the software with professional support, available through an online ticket system. This ensures that any technical issues or challenges can be addressed promptly, providing peace of mind for businesses that rely on VPN for their operations.

Cross-Platform Compatibility

OpenVPN devices

OpenVPN Access Server is designed to work on multiple operating systems, making it highly versatile. Whether you’re using a Windows PC, a Mac, an iOS device, or an Android smartphone, you can easily connect to OpenVPN.

This feature is particularly useful for businesses with a diverse range of devices, as it eliminates the need for multiple VPN solutions.

Security Protocols

OpenVPN uses its own protocol, which is based on the TLS (Transport Layer Security) authentication protocol. This is coupled with additional security measures like credentials and certificates.

An optional MAC address lock adds an extra layer of security by binding the VPN connection to a specific device.

Certificate Management

The software automates the complex task of VPN certificate management. It not only generates and provisions certificates but also allows for the integration of an external Public Key Infrastructure (PKI).

This is beneficial for organizations that already have a PKI in place and want to maintain control over it.

Multi-Factor Authentication (MFA)

Security is further enhanced with multi-factor authentication options. The software comes with built-in MFA using Time-based One-Time Password (TOTP).

For those who require additional layers of security, third-party solutions like Duo Security and LastPass can be integrated through post-auth plugins.


Access Control

This feature allows network administrators to fine-tune who gets access to what within the network.

Access control rules can be set based on user or group profiles, specifying which IP addresses and subnets they can access. This is crucial for segmenting network access based on organizational roles or security levels.

Tunneling Options

OpenVPN provides two types of tunneling: full-tunnel and split-tunnel. In full-tunnel mode, all of the client’s internet traffic is routed through the VPN, providing complete security but potentially slowing down the connection.

Split-tunnel mode allows only specific traffic to pass through the VPN tunnel, offering a balance between security and performance.
