Cisco AnyConnect licensing is PER USER based and pooled across your firewall platforms. (No longer need to purchase licensing per firewall)
*When in doubt….just buy APEX license (IMHO not a huge uptick in pricing)
Example 1 – 5 users, basic vpn, Umbrella Roaming module = 5 AnyConnect Plus Licenses
Example 2 – 25 users, basic vpn, Umbrella Roaming module, Network visibility module = 25 APEX licenses (no need to purchase a license for plus and APEX)
