Hi,
Thank you for posting in Symantec community.
I would be glad to answer your query.
It's possible to integrate SEP with Vshield and no additonal product is required just need to install additonal componenets provided by Symantec.
The Symantec Endpoint Protection Security Virtual Appliance is a Linux-based virtual appliance that you install on a VMware ESX/ESXi server. The Security Virtual Appliance integrates with VMware's vShield Endpoint. The Shared Insight Cache runs in the appliance and lets Windows-based Guest Virtual Machines (GVMs) with the Symantec Endpoint Protection client installed share scan results. Identical files are trusted and therefore skipped across all of the GVMs on the ESX/ESXi host. Shared Insight Cache improves full scan performance by reducing disk I/O and CPU usage.
You can deploy the vShield-enabled Shared Insight Cache into a VMware infrastructure on each host. The vShield-enabled Shared Insight Cache makes file scanning more efficient. You can monitor the Security Virtual Appliance and client status in Symantec Endpoint Protection Manager.
A vShield-enabled Shared Insight Cache runs in a Symantec Endpoint Protection Security Virtual Appliance. Windows-based Guest Virtual Machines (GVMs) use VMware vShield Endpoint to access the Shared Insight Cache.
Note: Symantec supports the use of a vShield-enabled Shared Insight Cache only in VMware ESX/ESXi infrastructures.Reference article:
