Overcoming Detection Gaps of Deep Packet Inspection Tools

White Paper


On any network, accurate detection of threats, malware, command and control, and data leakage depends on accessing the content. This does not refer to the content of a packet, but rather the content of the entire network session because the content may be encapsulated or obfuscated under multiple layers of encoding, embedded in office documents and PDFs, encoded in email messages, or payloads of web pages.

The most common form of content inspection, Deep Packet Inspection, is designed to quickly examine individual packets rather than the lowest level of encoding. Fidelis Cybersecurity developed and patented its Deep Session Inspection® (DSI) technology as a critical capability of Fidelis Network® to overcome these limitations. Extracting and understanding content within the context of a network session is crucial for detection of content-focused security problems across all phases of the kill chain, from initial attack through to data leakage. Find out more about the benefits of Deep Session Inspection, how it can be applied, and the visibility and analysis functionality it affords security teams.
