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.
