Hi all the Cortex MCP Server download under Settings → Configurations shows on commercial tenants but is missing entirely on our FedRAMP / Federal tenant (not a permissions issue). Is it on the roadmap for Federal environments, and is there an expected timeline for rollout? Thanks!

DLP (DataPatrol) signed DLL injection into Word blocked by agent — permanent exception?

Our DLP watermarks documents by injecting a signed DLL into WINWORD.EXE on print. The Cortex agent blocks the injection — page prints with no watermark, DLL never loads. Works fine with the agent removed. Persists in Report mode, generates no alert/prevention event. Tried a Disable Prevention rule (signer + thumbprint, all modules, global) — no ...

Anyone else having XDR communication problems?

Starting later in the day on June 24, we started seeing endpoints show 'No connection to server' when opening the Cortex console on the endpoint. Endpoint tasks like collect firewall logs, pause protection and live terminal all fail. Some systems shows that they ARE connected to our tenant but trying to live terminal into them fails.

Any specific post-installation procedure / configuration required to make sure the protection running on Mac without affecting performance ?

Cortex XDR and Sandboxie

Hello, We have installed Cortex XDR on a VM that also runs a sandbox tool (Sandboxie). As long as Cortex XDR is enabled, processes cannot be started within the sandbox (e.g., msedge.exe, cmd.exe, explorer.exe). It only works if I create a "Disable Injection and Prevention" rule for these processes. How can I resolve this permanently? I suspect...

We haven’t seen any corresponding case or alert in the console, meaning Cortex XDR is not actively blocking anything. This raises the following questions: 1) Wildcards in Op...
