Citrix SD-WAN Solution Guide
The following sections describe how you use the Citrix SD-WAN with Prisma Access to
provide next-generation security on internet-bound traffic.
| Where Can I Use This? | What Do I Need? |
|---|---|
|
|
To use this Solution Guide, you need a knowledge of SD-WAN routing principles.
You onboard your SD-WAN edge devices using a remote network connection between the edge
device at the branch site, HQ, or hub to Prisma Access. To do this you Onboard a Remote Network, ensuring that you
use supported IKE and IPSec cryptographic settings detailed here.
The following table documents the IKE/IPSec crypto settings that are supported with
Prisma Access and the Citrix SD-WAN.
A check mark indicates that the profile or architecture type is supported; a dash (—)
indicates that it's not supported. Default and Recommended settings are noted in the
table.
