US Patent 11057349 Cloud-based multi-function firewall and zero trust private virtual network

Method and system embodiments for providing a cloud-based multi-function firewall are described. A method includes retrieving device information associated with a network-enabled device. The device information is transmitted to a secure cloud for configuring a virtual private network (VPN) connection between the secure cloud and the network-enabled device. Cloud information specifying a cloud server in the secure cloud is received from the secure cloud. The secure cloud generates the cloud information based on the device information. Domain name service and routing functions are updated to forward network requests to the cloud server specified in the cloud information. The VPN connection to the secure cloud is established based on the cloud information such that network traffic to and from the network-enabled device is routed through the VPN connection to the cloud-based multi-function firewall implemented on the cloud server.
