Norton Security with or without firewall

When I logged in to Norton address to read about Norton Security, I noted that the web address was us.norton.com/norton-security-antivirus, which implies that Norton Security has eliminated the firewall that Norton 360 has. Besides I read through the features of Norton Security; nowhere was a firewall mentioned. Is my understanding correct that Norton Security has no firewall? Firewall is a very important component of a web protection software. I would appreciate anyone explaining what really Norton Security is. I was thinking of combining Norton Internet Security on one computer of mine and Norton 360 on my second computer and also add my android mobile phone so that I could use a single software for all.

Thank you and regards
