2 license tiers: Plus (vanilla VPN) and Apex (client posture assessment, client-less VPN, other stuff).
Each one available as 1/3/5 year subscription, plus software update subscription which also must be purchased (I think?)
The hardware and licensing mechanics are still set up for the old system, where you license a box for some amount of concurrent users depending on box size… But under this new model, they let you redeem the license 99,999 times (one redemption for each serial number in your environment)
You have to buy a license for every potential human user in your enterprise, not the hardware capacity you own. So an enterprise with 100,000 employees who could use the VPN would need 100,000 licenses, even if they only owned a single ASA with a hardware capacity of just 25 users.
Conversely, an enterprise with monster ASA boxes everywhere (huge capacity), but a user policy (AD group or whatever) that only allows 5 specific users to VPN in would need just 5 licenses.
It doesn’t matter how many devices the humans have, nor how many times they’ll be logged in. Only the user count. They’re counting named users.
None of it is enforced AFAIK. No matter what license you buy, when you apply it, the entire capacity of the box gets enabled. Just like the old licensing model.
The subscription-based licenses are pretty cheap.
Somewhere along the way, after making this change, they re-introduced perpetual licensing. Crazy money though.
