After updating Carbon Black Cloud sensor to version 188.8.131.52 the endpoint status will show as bypassed. After attempting to remove the endpoints from bypass the endpoints will loop back to the same status.
VMware Carbon Black Endpoint Standard (CB Defense)

VMware Carbon Black Cloud support confirmed that the logs above show that the KEXT was not approved or not working for the sensor.
Vmware Carbon Black also reviewed the Server and noticed that the Network Extension was not approved for the endpoints. This causes the sensor to not provide full data to the server.
