You can prevent attackers from using the LivePerson Monitor Tag in unauthorized domains, and visitors from luring agents to download malicious content.

Admins are able to define domains which are allowed to send monitoring data, as well as from which domains they are willing to accept engagements. You can define an allowed domain by adding it to your whitelist.

On the flip side, you can add a domain to a blacklist, allowing you to prevent unwanted activity, such as the placement of a chat button on a website.

Once the capability is enabled, only the domains in the whitelist will be monitored and domains in the blacklist will not be monitored.

To achieve this end, admins block domains by adding them to the blacklist, and allow domains by placing them on the whitelist, as shown in the illustration below. Once a domain appears on the blacklist, it is blocked from sending monitoring data (even if it also appears on the whitelist).

To include multiple subdomains, you can use wildcards (*.) at the beginning of the domain name. For example, to include both and use the syntax *

To include domains and subdomains you should add both domain name and subdomains separately. For example, to include and and add both and * to the whitelist.

It is important to add Liveperson's domains (,,, to the list of monitored domains, to ensure your service works efficiently.

To enable monitored domains:

On the Web Tag page, click Manage Domains.

Type in the domain names in the relevant fields. Ensure you include the LivePerson domain names mentioned above.

Click Enable and then click Save.

Any updates to the whitelist or blacklist will take effect within 30 minutes.
