You can use URL filtering to control which URLs users can access. You can use the console to create allow and deny lists of URLs as a portal setting, or by uploading a browser policy JSON file with URL filtering included. You may also control outbound communication from a portal to the internet by connecting your VPC to a web proxy. You can set proxy settings using Chrome’s policies built into the web browser by setting up an HTTP outbound proxy. For example, if you use a web proxy as the gateway to the internet, you can implement preventive security controls, such as domain allow-listing and content filtering.
