CPInfo is an auto-updatable utility that collects diagnostics data on a customer's machine at the time of execution and uploads it to Check Point servers (it replaces the standalone cp_uploader utility for uploading files to Check Point servers).

The CPInfo output file allows analyzing customer setups from a remote location. Check Point support engineers can open the CPInfo file in a demo mode, while viewing actual customer Security Policies and Objects. This allows the in-depth analysis of customer's configuration and environment settings.

 Packet filtering, stateful inspection, and application layer firewall are technologies used to deny or permit network traffic based on different criteria. Packet filtering is a basic firewall technology that examines the header of each packet and compares it to a set of rules to decide whether to allow or drop it. Stateful inspection is an advanced firewall technology that tracks the state and context of each connection and applies security rules based on the connection information. Application layer firewall is a firewall technology that inspects the content and behavior of applications and protocols at the application layer of the OSI model and enforces granular policies based on the application identity, user identity, and content type.
