Licensing SEP non-persistent VDI guests

How SEP is licensed for non-persistent VDI environments.

I know we have the capability to purge non-persistent VDI clients separately from the persistent physical and virtual clients in SEPM.

Is it as easy as taking the the active count based on the default 10 day purge for non-persistent?

Do they need to license every VM that spins up?

SEP on VDI clients are licensed the same way as the physical clients. It counts towards the overall license count.

It is based on the concurrent active number of VDI images.  At any given time the current number of active systems is how many they need to be licensed for.  If during peak times they exceed the number of licenses they purchased then they have breached the license agreement.

NOTE: Online non-persistent clients count toward the number of deployed licenses; offline non-persistent clients do not.

Thank you for posting in Symantec community.

I would be glad to answer your query.

Acommon problem with non-persistent VDI is the case of orphaned clients. Each time a VM is created, 
the SEP client registers with SEPM. Since the client is active only for the duration of the user’s work day, this fills up the SEPM database with entries for clients that are no longer around. Additionally, while the orphaned clients are in the SEPM database, they use up a client license.
You can configure the Symantec Endpoint Protection client in your base image to indicate that it is a 
non-persistent virtual client. You can then configure a separate purge interval in Symantec Endpoint 
Protection for the offline guest virtual machines (GVMs) in non-persistent virtual desktop 
infrastructures. Symantec Endpoint Protection Manager removes the non-persistent GVM clients that 
have been offline longer than the specified time period. This feature makes it simpler to manage the 
non-persistent GVMs in Symantec Endpoint Protection Manager.
In the management console you can configure the settings:
SEPM --> Admin --> Domain --> Edit domain properties --> General --> Delete the non-persistent clients that have not been connected for specific period.f
Even though license are over deployed in Enterprise Edition system will be protected by SEP. EE uses soft enforcements. Content update downloads continue from all the sources.
