Cortex XDR Connection method

Hi, While monitoring network traffic during our deployment, we noticed that all traffic between the endpoint and the XDR portal (<xdr-tenant>.xdr.<region>.paloaltonetworks.com) is one-directional (outbound).

We have private Linux servers in a separate environment with no internet access. However, after deploying the agent and reviewing firewall logs, we did not observe any traffic from the endpoint to the XDR portal.

Could someone provide more details on how the connection works on the backend?

Hi @A.Alharbi095930, thanks for reaching us using the Live Community.

By default in the Agent Settings profile, the agents will try to get the Content Updates from other agents using P2P, then Broker VM if there is any, and then goes to the tenant over internet.

If there is another agent in the same network with the CU downloaded, it will be shared.

You have more information in this document.
