The evolving nature and delivery schemes of viruses, malware and spyware have radically changed the scope and best practices of network security. 

In the pursuit of application-level protection, Deep Packet Inspection (DPI) has become the preferred approach. There are two core DPI approaches: proxy-based and streambased DPI. 

Both have fundamentally different ways of solving the problem, each with a distinctly different impact upon network latency and performance.
