The OpenConnect NetworkManager plugin allows for secure VPN connections through the NetworkManager framework. It provides a simple interface for configuring and connecting to OpenConnect VPN servers, and can be used on various Linux-based operating systems.

The PPTP plugin enhances NetworkManager to support the Point-to-Point Tunneling Protocol (PPTP). This allows for secure and private communication between remote users and a private network.

The VPNC plugin is an add-on for NetworkManager that allows for secure remote access using the Cisco VPN protocol. It offers users an easy-to-use interface for configuring VPN network connections and provides secure encryption for all data transmitted between a user's computer and the remote VPN network.
