To change an approved publisher to unapproved, go to the Publisher tab on the Software Rules page, select the check box next to its name, and select Remove Publisher Approval on the Action menu. This action removes approval; it does not ban the publisher.
You also can remove approval using the Publisher Details page.
Any computers that have installed or run software from this publisher while it was approved continue to be able to run the software. All existing instances of software from an approved publisher are locally approved, and the local approval is not removed by the change in publisher status on the Carbon Black App Control Server.
