You can use the Portal system with domains that you own or control. To do so, you must configure a CNAME record and point the record to portal.phishingbox.com. Below are links to "How To" for some common registrars.
Once the CNAME record has been created and DNS has had time to propagate the update, it may be used as a custom domain within the Portal. NOTE: DNS may take up to 48 hours to propagate the updates.
To add the custom domain in Portal, go to the desired template and edit the landing page. Then change the CNAME for the template.
Then select "Custom" from the drop down menu, and enter the domain name for which a CNAME record was entered. To ensure that is it working properly, click the Test CNAME link. You should get a TEST PASSED if everything is working properly. NOTE: make sure the custom CNAME matches was was configured in the DNS record.
