Rulename	Netskope Client - Private Access disabled by user
Description	Detects Netskope Client devices where the user disabled the Netskope Private Access (NPA) service. All matching client-status events in the 6-hour window are collected into a single alert, grouped per device, so repeated disable events on the same device are reported once. A user disabling Private Access removes zero-trust access controls from the device.
