Access Server features overview

Access Server installs on a Linux OS with installation options to meet the needs of your network.

VPN clients connect from Microsoft Windows, macOS, iOS, Android, and Linux systems.

You can download installation packages for Linux, virtual machines, or cloud platforms.

User authentication includes a built-in system with web-based management or external authentication with PAM, LDAP, RADIUS, or SAML.

Advanced authentication is supported through custom programming with Python.

Access Server includes built-in, fully automated VPN certificate management and provisioning. External PKI is also possible for full control over an existing integrated PKI.

VPN tunnels are secured with the OpenVPN protocol using TLS authentication, credentials, certificates, and MAC address lock (optional).

Multi-factor authentication is supported in various forms: TOTP MFA is built-in; Duo Security can be added with a post_auth plugin, and LastPass can be added with a post_auth plugin.

Access control rules can specify user or group access to IP addresses and subnets and allow or disallow direct VPN client connections.

Full-tunnel and split-tunnel redirection: All VPN client internet traffic goes through the VPN tunnel or only specified traffic, respectively.

Professional support is provided by the OpenVPN, Inc. team, with our online support ticket system staffed by our global team of professionals.
