OpenConnect is an SSL VPN client initially created to support Cisco's AnyConnect SSL VPN.
It has since been ported to support the Juniper SSL VPN (which is now known as Pulse Connect Secure), the Palo Alto Networks GlobalProtect SSL VPN the F5 Big-IP SSL VPN, and the Fortinet FortiGate SSL VPN.
An openconnect VPN server (ocserv), which implements an improved version of the Cisco AnyConnect protocol, has also been written. You can find it on Gitlab at https://gitlab.com/openconnect/ocserv.
If you're looking for the standard vpnc-script, which is invoked by OpenConnect for routing and DNS setup,
you can find it on Gitlab at https://gitlab.com/openconnect/vpnc-scripts.
