Security Gateway (SG) is usually deployed on the perimeter to control and secure traffic with Firewall and Threat Prevention capabilities.

Security Management Server (SMS) defines and controls security policies on the Gateways. It can also be used to as a log server with built-in system of log indexing (SmartLog) and event correlation (SmartEvent -- a SIEM-like solution for Check Point products). Usually, SMS is the main element of central management with multiple Security Gateways in operation. Nevertheless, you need an SMS even if your security system has a single gateway only.

SmartConsole is a GUI administration tool to connect to SMS. Through this tool, a security administrator is able to prepare and apply security policies to the Security Gateways.
