Is Sophos Central free?? Locked out do to authentication issue after activating Sophos Central Trial account.

With the AP access points going EOL next year, users are saying that they will only be managed through Sophos Central if using the XG firewall. People here say it's free, but customer support wants me to "chat" with them over price, I'm a home user so I don't want to be haggled by a salesman. So I'm a bit confused. Even I can't get an answer by searching around the internet.

What is the purpose of this obscurity?
