Before you get started with Cortex XDR, consider the following.
Determine the amount of log storage you need for your Cortex XDR deployment. Talk to your partner or sales representative to determine whether you must purchase additional storage within the Cortex XDR tenant.
Determine the region in which you want to host Cortex XDR and any associated services, such as Directory Sync Service. If you plan to stream data from a Cortex Native Data Lake instance, it must be in the same region as Cortex XDR.
Review the Cortex XDR agent support for operating systems and versions. For more information, see the Cortex XDR compatibility matrix.
For the Cortex XDR Pro per Endpoint license, determine the necessary bandwidth required to support the number of agents you plan to deploy. Allocate 1.2Mbps of bandwidth for every 1,000 agents. This requirement scales proportionally. For example, if you plan to have 100,000 agents, you will need to allocate 120Mbps of bandwidth.
