Deep Packet Inspection (DPI), also known as complete packet inspection, is used to monitor network traffic at the packet level. Unlike conventional Packet Filtering, DPI can analyze not just headers but examine protocols and application data as well as the actual content of packets. Our advanced DPI-based packet classification offers complete IP traffic visibility up to Layer 7. It enables traffic classification, automatically detecting over 1600 applications and 400 protocols in real time with a high degree of accuracy. We can identify applications, protocols, and packets with a certain type of payload, even when traffic is encrypted or obfuscated, and react accordingly.

Since DPI allows IT teams to categorize traffic based not just on data — like origin server IP, destination IP, or ports used — but also things like traffic type, relative or actual payload, or protocol, they can search for non-compliance with policies or filtering rules, spam, viruses, and malware. Based on inspection results, they can then filter out low-risk flows to protect existing tools or classify, reroute, drop, mask, or alert on packets that match.

This kind of packet inspection keeps tools running efficiently, provide immediate insight into network threats or slowdowns, and determine whether reduced throughput is caused by the network or an application.
