Wildcards in Destination Lists

Wildcards support top-level domains (TLDs) to allow broad allows or blocks for destination lists.

Every domain in a block or allow destination list has an implied left-side and right-side wildcard.
Note: Asterisks (*) are not supported.

Destination List EntryImplied Wildcard

It is not possible to use an asterisk in a wildcard to navigate to a different part of the domain. For example, the following wildcards will not work:

  • *.domain.com
  • subdomain.*.com
  • sub*.com
  • domain.*

Adding domain.com to a destination list results in requests to domain.com or its subdomains, such as www.domain.com or www.domain.com/path.

Use caution as adding a TLD to an allow list may open your network to malware threats, and adding a TLD to a block list may block more than expected due to CNAMEs and CDNs.


Regular Expressions Not Supported

Regular expressions in URL paths are not supported.
