Portal customization and branding for customer facing page

Portal customization and branding for customer facing page

I have a internal request in my organization to remove any branding that our customers will see that have "Zoho Support" displayed to our customers from the customer portal.  I have checked the Portal Customizer and looked at the HTML code, but i don't see where that might reside.  Is there a place to remove branding such as this from the site:



Or can we change it to state something different so it's branded to our company and not Zoho?
