DPI is a next-generation technology capable of inspecting every byte of every traffic packet that passes through a DPI device, that means packet headers, types of applications and actual packet content in real time which were previously impossible to do using advanced proxies, or stateful firewalls systems.
Deep packet inspection (DPI) is one of those more sophisticated firewall techniques. In addition to blocking traffic to or from known Tor relays, a DPI firewall can be configured to look deeper into the network packets, beyond the source and the destination addresses. Deep Packet Inspection is a technique used by cloud-generation firewalls to inspect all network data to filter out malware and unwanted traffic. In the age of fast-evolving threats, deep packet inspection is a core part of network security strategies. What is Deep Packet Inspection (DPI)? | Dec 05, 2018 · Deep packet inspection is a form of packet filtering usually carried out as a function of your firewall. It is applied at the Open Systems Interconnection's application layer. Deep packet inspection evaluates the contents of a packet that is going through a checkpoint. Deep packet inspection (DPI) is an advanced method of examining and managing network traffic. It is a form of packet filtering that locates, identifies, classifies, reroutes or blocks packets with specific data or code payloads that conventional packet filtering, which examines only packet headers, cannot detect. Jan 28, 2020 · Your router already does a lot – NAT firewall, stateful inspection, etc. – adding DPI makes the whole network even more complex. DPI raises privacy concerns. DPI can be used for good and bad. It can help you block malware and hackers, but it can also be abused by ISPs and governments to block certain content and monitor what you do online. There are several different Deep Packet Inspection (DPI) application categories built-in to EdgeOS that can be matched on using firewall policies. Examples are the Streaming-Media and Social-Network categories which each has its own list of apps (websites).
