SecureXL (Secure acceleration) : With SecureXL, you can maximize the performance of the Firewall without compromising security. Using SecureXL on a Security Gateway, several CPU-intensive operations can be processed or handled by virtualized software rather than the firewall kernel. In this manner, the Firewall can better inspect and process connections more efficiently, as well as accelerate the throughput and connection rate.
ClusterXL (Smart load balancing) : ClusterXL involves a set (cluster) of identical Check Point Security Gateways which can be connected in a way that if one (Security Gateway) fails, another replaces it immediately. ClusterXL maintains business continuity through high availability and load sharing. ​Whenever the gateway or network goes down, the connection is seamlessly redirected to the backups, which ensures business continuity. ClusterXL distributes traffic among clusters of redundant gateways, thereby combining the processing power of multiple machines to increase overall performance or throughput.
CoreXL (Multicore acceleration) : When CoreXL is enabled on a Security Gateway, the Firewall kernel is replicated multiple times and each replica (instance) runs on a single processor core. All instances are complete firewall kernels that handle and inspect traffic concurrently, thereby enhancing security gateway performance. Each Firewall instance processes traffic through the same interfaces and applies the same gateway security policies. High security and high performance are achieved simultaneously with CoreXL.
