VPN Client Pro - VPN Connection & Security

This application allows users to establish connections with various server types such as OpenVPN (TUN/TAP), SSTP, WireGuard, SoftEther, ShadowSocks, SSH Tun (using the ssh -w option which supports TUN and TAP), OpenConnect (ocserv) servers, and Cisco AnyConnect SSL gateways.

The fundamental OpenVPN functionality is available at no cost. However, to access additional protocols and features, a license purchase is necessary.
