What is the main difference between CIS and CIS pro?

What is the main difference between CIS and CIS pro? I am using only the firewall part, so does the pro version offer something the free does not? The website soed not tell it clearly, reading about both the free version seems to be better and larger solution than the Pro!

Both provide the same level of protection.

Pro has a remote and telephone support and TrustConnect (wi-fi security app)

Pro doesn’t have TrustConnect. Atleast here, I downloaded Free 1 Year CIS Pro, got GeekBuddy but no TrustConnect here.

Thanxx
