What you can do with OpenVPN at a glance:

OpenVPN is a multi-platform SSL VPN solution.

It provides encrypted network access at OSI Layers 2 and 3 using industry-standard SSL/TLS protocols!

Challenge/Response Authentication

You can add your own authentication mechanism to the OpenVPN Access Server. The authentication module can ask users as many questions as needed, process their responses, and determine whether they are authorized to access the network. In addition to a username and password, you can also use OTP (One-Time Password) and two-factor authentication (2FA).

Clustering

With full UCARP integration, if the active VPN server goes offline or shuts down, another server immediately takes over. In addition to the primary server, multiple backup servers can be configured, with the backup servers receiving their settings from the primary server. This simplifies system administration and enables a variety of disaster recovery scenarios.

macOS Integration

OpenVPN clients support both the macOS Keychain and the Windows CryptoAPI. This means that users logged in to Windows or macOS can choose to use the password-saving option. For connections that use certificates and private keys, the relevant certificate and private key can also be automatically located and retrieved from the system’s secure key store.

Client-Side Secure Code Execution

OpenVPN Access Server provides a flexible method for executing code. Code placed on the Access Server can be pushed to client devices and executed locally. These code snippets or scripts can also be digitally signed for security. The operating system running on the client side does not matter.

Multiprotocol

OpenVPN services can be configured to listen on both TCP and UDP protocols. Clients can automatically adapt as well: they first attempt to connect via UDP, and if the corporate network or current environment does not allow it, they can connect to the server via TCP instead. This process is fully automatic. When the service is configured to use HTTPS port 443, connections can generally be established from almost anywhere.

VPN without browser

Traditional VPN solutions often require users to open a web browser and keep it running after the connection is established. With OpenVPN Access Server, this method can be completely disabled if preferred. One of the key advantages is that users are not exposed to browser- or Java-based security vulnerabilities, nor do they need to modify existing browser security settings.
