Deep packet inspection (DPI), also known as packet sniffing, is a method of examining the content of data packets as they pass by a checkpoint on the network.
What is DPI and SPI?
In short, SPI is used to get the firewall act as a router or layer 3 device whereas DPI makes the box to act as a layer 3 security appliance. So with DPI, protection to network is guaranteed.

What is a DPI engine?
A DPI engine works by analyzing a variety of different traffic characteristics at the flow level. DPI vendors use various techniques including pattern matching, deep protocol dissection, semantic and conversational awareness, behavioral analysis and flow registration to figure out what the traffic actually is.
