ETP allows you to create two broad categories of lists: block lists and exception lists. The actions associated with these lists are prioritized over Akamai Security and classifications in ETP. If domains, IP addresses, or URLs are configured in multiple lists with conflicting actions, ETP selects the action based on a priority. For more information, see Policy conflicts.

Each entry in a list is counted separately. For example, in a custom list, each domain and IP address is counted as a separate entry. ETP allows you to have a maximum of 200,000 list entries.

An enterprise can create a maximum of 100 lists. If your organization needs to create more lists, contact your Akamai representative.

You must deploy your work after creating, modifying, or deleting a list. The deployment takes approximately 20-30 seconds.

Block Lists

Block lists are used to define whether a policy should block access or monitor access when users make requests to outside resources.

There are three types of block lists:
  • Custom lists: Defines known and suspected domains and/or IP addresses that you want to block or monitor, or domains and URLs that you want to block or monitor.
  • Top-level domain lists: Defines country-code top-level domains (ccTLD) and generic top-level domains (gTLD).
  • URL block lists: Defines URLs that you want to block or monitor.

Exception Lists

Exception lists are used to define exceptions to the policy actions defined for the block lists. The ETP Proxy does not scan the domains, IP addresses, URLs, or file hashes in exception lists. By default, when a user associates an exception list to a policy, it’s assigned the bypass policy action.

There are three types of exception lists:
  • Custom exception lists: Specifies domains and IP addresses that are bypassed by ETP Proxy.
  • File hash exception lists: Specifies the hashes of files that you don’t want scanned by data loss prevention (DLP).
  • URL exception lists: Specifies one or more URLs that you don't want the ETP Proxy to scan.
