The techniques described herein relate to authorizing networked devices to access protected network zones and/or network resources in a private network. In response to a first access request, a network appliance requests full compliance information from the networked device. The received compliance information is stored in a database. Subsequently, when the compliance information on the networked device changes, the network device sends updated compliance information to the network appliance. The network appliance reevaluates the compliance state of the networked device based on the updated compliance information and the compliance information stored in the database.
