OpenVPN Client

OpenVPN Client is a VPN client application designed specifically for Android users. It offers granular access control and supports multiple authentication methods, allowing administrators to define user permissions and access scopes for specific users. With OpenVPN Client, users can establish encrypted data transmission tunnels using the OpenVPN protocol to securely connect to a VPN server. Please note that the application itself does not provide VPN services; instead, it connects to existing VPN servers.
