Wolfram Computation Meets Knowledge

How do I disable my Wolfram product from accessing the internet?

Wolfram products and Wolfram Language functions access the internet for a variety of purposes:

  • Wolfram software products may access Wolfram servers to establish the valid use of the product or to download incremental product updates.
  • The Wolfram Language contains various high-level functions that may, in the background, communicate with or gather data from Wolfram servers or specific third-party servers such as the Wolfram Cloud, Wolfram|Alpha, Wolfram repositories or Wikipedia, among others.
  • The Wolfram Language offers a full suite of low-level functions to program communication via the internet.

Restrict the product from using the internet

You can turn off your Wolfram product’s online communication or that of high-level Wolfram Language functions with a convenient switch in the Preferences menu. Note that in this case, individual Wolfram Language functions may no longer work properly or the continued use of your product may be affected.

  1. In the program menubar, select Edit ► Preferences (On macOS, Mathematica ► Preferences).
  2. Select the Internet & Mail tab.
  3. Uncheck the “Allow the Wolfram System to access the Internet” option to disable the connection.

Restrict user-written code from using 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. Sandboxing will have to be done by your system administrator department.
