When an endpoint is isolated in Cortex XDR, all network traffic to and from the device is blocked by default, except for traffic explicitly required to communicate with the Cortex XDR management console.
To allow specific, additional administrative or troubleshooting traffic (such as allowing a specific set of IT admin IP addresses to RDP or SSH into the isolated machine), you must configure Isolation Exceptions:
Where to find it: In the Cortex XDR console, you navigate to Settings -> Configurations -> Endpoint Tuning -> Isolation Exceptions.
How it works: Within this section, you define the network rules (IP addresses, ports, and protocols) that the agent should respect even when a "Hard Isolation" or standard isolation command is active on the endpoint.
