AOS, when used as a VPN Gateway, must be configured to route sessions to an intrusion detection and prevention system (IDPS) for inspection.

Remote access devices, such as those providing remote access to network devices and information systems, that lack automated capabilities increase risk and make remote user access management difficult at best.
