Prevent Internet Access from the Wolfram Language

Wolfram Language functions access the internet for a variety of purposes:
to access Wolfram servers to establish the valid use of the product or to download incremental product updates

Choose , select the Internet Connectivity tab and uncheck “Allow the Wolfram System to access the internet”:
To prevent user-written code containing low-level HTTP-request functions from accessing the internet, the installation of your Wolfram product needs to be sandboxed on the operating system level. Please consult with your system administrator for more information regarding sandboxing.
