Due to a known issue on with Apple drivers, when packet filtering is enabled on the network extension, it may cause networks issues.

To avoid this, the network extension should be disabled. This will not allow to isolate the endpoint, or run the latest version of Host Firewall.

In certain cases, a combination of firmware and software cause networking issues when the Cortex XDR network extension runs with packet filters. In this case, the packet filter is partially disabled, causing some limitations in the Host Firewall and Network Isolation features.

Sometimes 32bit applications running on Windows 7 endpoints could halt due to a misconfiguration in Shellcode detection for BTP.
