at theapplication layer. It works with stateful packet inspection (SPI) and deep packet inspection

(DPI) and monitors incoming traffic. Like proxy servers, proxy firewalls work as a mediator and prevent direct contact between different systems. They have their own IP addresses and use them to receive data packets, which they then forward to the destination address via a new connection. Proxy firewalls have extensive monitoring functions in which they document the connections and security problems for security management.
