Elements device’s isolation status is stuck on pending

Issue:

When Elements Endpoint Detection and Response (EDR) detected a high or severe level risk on a device, the automatic network isolation feature triggered a host isolation but it didn't isolate the computer. The network isolation state remains pending on the portal. 

What can cause the automated isolation action to fail? 

Resolution:

Ensure your Windows Defender firewall is controlled by WithSecure and that you do not have firewall rules or configurations via GPO. Rules and configurations created via GPO override any firewall rules created by the WithSecure firewall profile, even isolation rules.
