Setup Sophos XG firewall for Cpanel mail hosting

Question

I am familiar with Sophos Central email Gateway but now I want to work around the Sophos XG firewall Email Protection. I am using Cpanel hosting (My web hosting company provided) for mail as well. I want to scan my all emails with my Sophos XG firewall. I have some doubts and questions: 
 1. How to configure MX Record on my DNS management? will I redirect to XG Firewall same as Sophos Central Gateway? 
 2. How Sophos XG firewall will sit in the protection 1. In between MX record and Mail server or 2. In between Mail Server (Inbox) and client system inside my office. 
 3. Will it provide the same level of security as Sophos Central email gateway? 
 
 Please guide something.

The point is: Central Email and XG Mail are both MTA&acute;s. https://en.wikipedia.org/wiki/Message_transfer_agent 
 So both works the same way. 
 Central Email has a higher protection level (More features like DKIM, DMARC, SPF etc.). 
 But you can "combine" both products. 
 If you set your MX to Central and let Central point to XG, it will work. But you have to deal with two kinds of Quarantines etc. 
 
 XG can also perform a Streambased protection (Legacy mode SMTP or POP3/IMAP). To protect the Client to Mail Server Traffic.
