Prefilter Policy Definition: Prefilter Policy: A set of rules or criteria applied to incoming network traffic before it reaches the core network security infrastructure to improve efficiency and reduce the load on the main security measures.
Prefilter Policy is a set of rules or directives implemented in a network security system to screen incoming traffic before it reaches the main firewall for deeper inspection. It helps in reducing the workload on the main firewall by blocking or allowing traffic based on less resource-intensive criteria such as IP address, port number, or protocol type. By applying prefilter policies, organizations can optimize their network security infrastructure and improve overall performance.
