Definition of:stateful inspection. A firewall technology that ensures that all inbound packets are the result of an outbound request. Also called stateful packet inspection (SPI), it was designed to prevent harmful or unrequested packets from entering the computer.tateful inspection is the norm and generally a major component in every network firewall and personal firewall.
