AnyConnect client licenses allow the use of the AnyConnect desktop clients as well as any of the AnyConnect mobile clients that are available.

A client license enables the VPN functionality and are sold in packs of 25 from partners like CDW or through your company's device procurement.
Want to know more about AnyConnect licensing? Here are some resources:
Open a web browser and navigate to the Cisco Software Downloads webpage.
In the search bar, start typing 'Anyconnect' and the options will appear. Select AnyConnect Secure Mobility Client v4.x.
Download the Cisco AnyConnect VPN Client. Most users will select the AnyConnect Pre-Deployment Package (Linux 64-bit) option.
The images in this article are for AnyConnect v4.9.x, which was latest version at the time of writing this document.
If you purchased a license and you are unable to download AnyConnect, call Cisco Global Service Relations at +1 919-993-2724. Select option 2. You will need to know your Cisco ID (the one you use to log into Cisco.com) and the sales order number when you call. They will get that situation all straightened out.
Open the Terminal by pressing Ctrl+Alt+T on your keyboard. To navigate to the folder where you have downloaded the AnyConnect Client Package, use the command, ‘cd directory name’. For more information on the ‘cd’ command, click here.
cd [Directory Name]
In this example, the file is placed on the Desktop.
The directory may be different based on the location of the AnyConnect file download. For long filenames or paths, start typing some characters and press the tab key on your keyboard. The filename will auto-populate. If it doesn't even after you press tab twice, it indicates that you need to type more number of unique characters. Alternately, you can use the 'ls' command to list the files in your current directory.
The initial download is a tarball archive (several files packed into one), which must be extracted. The command ‘tar xvf filename’ will extract the contents to the same directory in which the initial file is located.
tar xvf [Filename]
For more information on the ‘tar’ command, click here.
Once the folder is extracted, use the ‘cd directory name’ command again to navigate into the folder.
cd [Directory Name]
After navigating into the main folder, ‘cd’ into the vpn sub-folder.
cd vpn
To run the AnyConnect install script, type ‘sudo ./vpn_install.sh’. This will begin the installation process using superuser permissions.
sudo ./vpn_install.sh
For more details on the 'sudo' command, click here.
Accept the terms in the license agreement to complete the installation by typing ‘y’.

Uncheck Block connections to untrusted servers to connect to these servers.
Using Terminal, navigate to the folder that contains the uninstall shell script using the ‘cd’ command.
In a default installation, these files will be located in /opt/cisco/anyconnect/bin/.
To run the Anyconnect uninstall script, enter ‘sudo ./vpn_uninstall.sh’
