Citrix XenApp - AV Exclusions - Non persistent Session hosts

Paul-Mathews — Tue, 23 Feb 2021 15:03:17 GMT

Hi all,

Anyone know if there are any optimisation guides for Cortex XDR in a XenApp non persistent enviroment ?

Should we add in some AV exclusions as mentioned by Citrix @ https://docs.citrix.com/en-us/tech-zone/build/tech-papers/antivirus-best-practices.html#performance-optimizations

Thanks,

Paul

Hi @Paul-Mathews,

I would recommend reviewing the following document for guidance on installing Cortex XDR in virtual environments. There are quite a few considerations to be made here, and this document does a great job at detailing those for Cortex XDR users.

Cortex XDR Agent for Virtual Environments and Desktops

As for Citrix AV exclusions, there are no known issues requiring optimizations at this time. If you encounter and performance issues with Citrix caused by Cortex XDR, our recommendation is to open a case with Support at https://support.paloaltonetworks.com/. For reference, the following link shows all of the known issues with Cortex XDR.

thanks Gjenkins

I have enabled the switches vdi enabled and ts enabled. The part I missed is the cytool VDI update. Do you know what the implications are by not setting this ?

Hi @Paul-Mathews,

I'm checking to see if there's anything more here, but according to the documentation for this optional step, it is only used to update the name in the Cortex XDR database if changed.
