A destination is an IP address (IPv4), URL, or fully qualified domain name. You can add a destination list to Umbrella at any time; however, a destination list does not come into use until it is added to a policy.

Security Intelligence Sources ... Custom Block lists or feeds (or objects or groups) Block specific IP addresses, URLs, or domain names using a manually-created list or feed (for IP addresses, you can also use network objects or groups.) For example, if you become aware of malicious sites or addresses that are not yet blocked by a feed, add these sites to a custom Security Intelligence list and add this custom list to the Block list in the Security Intelligence tab of your access control policy.
