Ensuring that specific domains are always accessible using the Allow List


The Allow List is a feature of Cyber Shield Domain Filtering. The Allow List enables you to override domain blocking. You can specify a list of domains that can be accessed even if they are present in a selected blocked domain category or are on the Block List.

Note: If you are using both Allow List and Block List, refer to the interaction between blocked and allowed domain names


  1. From the Shield page, click the pencil icon to access the Domain Filtering blocking settings.
  2. Click the Allow List tab.
  3. Add allowed domains to the Allowed List.
    • To add individual domains, click Add.
      • Matching entries appear as you type.
      • A warning appears if you specify a domain that exists in the Block List.
    • To batch add domains, upload a text (.txt) file with multiple domains by clicking Upload List.
      • The text file must be formatted to contain each domain in its own row, and domain names can’t contain asterisks.
      • When domain validation fails on an uploaded text file, an error icon displays with the domain, along with a description of the validation failure. Failed validation domains aren’t added to the Allow list and must be fixed manually.
      • Any existing entries are overwritten by the entries in the uploaded file.
  4. To download the domain names in the Allow List as a text file, click the Download list hyperlink at the bottom right.
