Deep Packet Inspection (DPI) as essential component for Cybersecurity


We are living in an era where everything is connected to the internet, as mobile data usage and IoT/IIoT have been growing at a rapid pace. And, growth is not expected to equilibrate yet, wherefore the protection of massive network traffic represents a challenging prospect. Ultimately, the gap between mobile applications and applications used in IoT/IIoT needs to be gapped to cope with this massive flow of data.

Your solution: DPI

Clearly there is a need to make intelligent decisions regarding secure traffic and routes. That is where DPI technology steps in. It describes a filtering device for a computer network, which examines the data part (instead of only a header) as it passes the inspection point. Being more specific, DPI is looking for security threats, violations or other defined criteria embedded in the packet. As a result, DPI decodes random strings of information, while turning them into contextual information about applications and contents. Therefore, this technology is becoming the cornerstone of network security in applications and IoT/IIoT era.

Why DPI?

As the need to analyze and detect potential threats before they can harm a company’s network has been emphasized, the importance of DPI can be stressed. By integrating DPI into your system, the engine can automatically make intelligent decisions about inflows and outflows of data to your company. This is done through the communication via IP, which enables DPI to supervise security devices (NFW) in either blocking or allowing data transfer. And, of course, it is not like in the old times, where a clear separation between good and bad packets was impossible. Even better, DPI classifies flows, as well as file content and extracts metadata for the security policy enforcement and content analysis.

Summarizing the above, DPI technology provides an understanding of application data critical across the security fabric. It is an essential tool for providing ultimate applications and data visibility, as well as ability to control the whole network. Finally, the integration of DPI engines makes security products stronger, as it is an additional layer in security, which minimizes the risk of successful security attacks.
