Q. How do I determine how many licenses to purchase? A. The AnyConnect Plus and Apex model is based on total authorized users that will make use of any AnyConnect service, not simultaneous connections (either on a per-ASA or shared basis) and not total active remote access users. As such, a user can connect with as many devices as he / she wants as long as the you have available hardware capacity and have not exceeded your purchased authorized user count. It is your responsibility to purchase additional authorized user licenses if their usage needs increase. If you currently support 30K simultaneous user connections but have 50K users who need AnyConnect services, you would be required to buy a 50K license. If you have 100K users who need AnyConnect services, you would be required to buy a 100K license. For unattended environments where there are not really individual users on the other side of a connection, each unattended device is considered a unique user.
