Cisco VPN Client for Linux

Hi all, do you know a recent decent Cisco VPN client suitable for CentOS7? I assume it is anyconnect-linux-64-4.1.02011-k9.pkg found here https://software.cisco.com/download/release.html?mdfid=286281283&flowid=7232... It asks for a contract. I want to connect to some Cisco firewalls with a valid support contract but I do not know whether it covers VPN client software. I try to figure out but look for alternatives to. I do not want to use the last free version (free as free in free beer) I found. The support for it ended in 2005.. Thanks for advice Peter
