Abstract
A network apparatus maintains a database of a plurality of virtual private network (VPN) protocols and respective VPN providers. A VPN protocol detection process is performed for determining a VPN protocol used by a computing device based on analyzing network traffic data and the database. In response to detecting the VPN protocol detection process failing or detecting a need to identify a respective VPN provider, an endpoint detection process for determining the VPN usage of the computing device is performed. In response to detecting the endpoint detection process failing or detecting a need to identify VPN usage time information, a traffic pattern search process for determining the VPN usage of the computing device is performed. Further action is taken to protect the computing device in response to detecting the VPN usage on the basis of the VPN protocol detection process, the endpoint detection process, and/or the traffic pattern search process.
