Deep Packet Inspection (DPI) is an advanced technique used by firewalls to inspect the content inside network packets \u2014 not just the header. DPI identifies applications, malware, commands, and behavior patterns traveling over the network. How DPI Works Reads packet payload instead of only IP\/port Matches signatures [&hellip;]"}
