By default, the Trellix Application Control prevents installation of ActiveX controls on endpoints, enforces memory protection techniques on endpoints, and prevents MSI-installers from running on endpoints. The "Feature Control" allows for those safeguards to be bypassed and in doing so renders the Trellix Application Control less effective.
