A new prevention policy has been created for assignment to the group named “Servers”.

The most likely reason the “Servers” host group is not available is that it is already assigned to another prevention policy. Falcon prevention policies are applied to hosts through host groups. When assigning host groups to a prevention policy, the console only presents groups that are currently available for assignment. The official prevention policy workflow states that after a host group is assigned to a policy, that host group no longer appears in the list of available groups. This prevents accidental duplicate assignment within the same policy assignment workflow and helps preserve predictable policy targeting. The group does not need to be disabled before assignment, and host type is not defined inside the prevention policy itself. The policy also does not need to be enabled before groups can be assigned; assignment can be configured before enabling the policy. Therefore, the unavailable “Servers” group indicates that it already has a prevention policy assignment.
