Check Point - SMART Client

SMART Client is the front end to managing the firewall. It contains the policy editor (rulebase), log file, status manager, among other things. It requires no license to install since it can't do anything on its own (but it does have a demo mode to allow you to access the features - you just can't install it on a real firewall).

Secure Client is Check Point's remote VPN client-to-site application that allows remote users encrypted access through a Check Point firewall. It also allows the administrator to enforce a desktop policy on the remote users controlling what traffic is allowed to and from the remote user's machine. This also does not require a license to install, but it doesn't do much of anything unless it connects to a Check Point firewall running a Policy Server (for desktop policy enforcement). The firewall itself would require a firewall, VPN, and Policy Server license.

Hope that helps -
