DPI is a surveillance technology that enables Internet service providers (ISPs) to monitor record and take informed decisions based on the content of data packets in real time. A data packet typically consists of a header and a payload. DPI enables the monitoring of the payload, i.e. the data part or actual content of a packet. A relatively recent technology, DPI helps service providers to analyze network traffic and perform high level analysis of the packet content. DPI can monitor, filter, read emails, website history, chats, and so on that pass through its system. It can help service providers to detect malicious software such as viruses or worms being transmitted over the network. DPI provides the service providers with a tool to address the increasing number of challenges such as explosive bandwidth demand, QoS, QoE while developing new revenue channels and ensuring competitive differentiation. DPI provides the ability to monitor, control and secure a network, equipping service providers with cyber security measures, cyber intelligence and real-time analytics. 
The global DPI market is expected to be USD 3.81 billion in 2018 growing at a CAGR of 36.6% from 2012 to 2018. Asia Pacific accounts for the major share of the DPI market and this trend will remain the same till the end of the forecast period. The figure below highlights market growth across different end use segments from 2012 to 2018. Some of the factors driving this market include increasing number of broadband users across the globe, increased mobile device penetration in the market and the increasing competitive pressure across network operators. With mobile devices like tablets and smartphones penetrating the market at a rapid pace, mobile network providers will need to turn to sophisticated network control techniques such as awareness of the device, application, user and location. However, there is still a lot of speculation about the actual benefits of DPI as opposed to invasion of privacy of the actual users. Privacy and net neutrality concerns remain some of the major restraining factors for this market. The main players in this market include Allot Communications, Procera Networks, Inc. and Sandvine Corporation, Arbor Networks, Cisco Systems, to name a few.
The research report on the global deep packet inspection (DPI) market provides in-depth analysis of the market based on its major type segments, end use application segments and geographies for the period from 2012 to 2018. The report provides complete understanding of the driving factors, restraints, and prevailing trends behind the popularity of deep packet inspection technology. It also presents estimates and forecast for all the market segments and explains the impact of various factors on these segments.
The shift to bandwidth heavy services ranging from voice and video to high-definition (HD) video on demand (VoD) is a clear indication of an increase in the burden on network infrastructure. In addition to this, security breaches on the network typically cost companies millions of dollars annually. These breaches not only affect the customers, but also service providers as post such security breaches, it is possible that the customers choose another provider that advertise higher security.
Report focuses on the various trends observed in deep packet inspection market such as, the rising incidences of cyber threats and growth in data processing power have spurred the growth of the deep packet inspection technology and this trend is expected to continue in the coming future. Substantial research and development and technological advancements in the DPI market are other important factors contributing to the growth of this market. Deep packet inspection (DPI) is a form of computer network packet filtering, which determines the data part of a packet when data packets pass through the inspection point. This method is implemented for searching spam, viruses, protocol noncompliance, intrusions, or defined criterion to determine whether the packet can be passed or if it needs to be routed to another destination for further check. 
An increase in the degree of competition between the service providers translates to the need for them to be able to develop and deploy different and enhanced offerings in order to stay ahead. Service providers need to be able to deal with the explosive demand for bandwidth, traffic management as well as application and network security. Being able to provide a high level of quality of experience (QoE) while ensuring new revenue models, is what will set the service providers apart. In order to be able to achieve the aforementioned tasks, service providers turn to deep packet inspection (DPI). DPI is a surveillance technology that enables Internet service providers (ISPs) to monitor, record and take informed decisions based on the content of data packets in real time. The report also provides better understanding of the market with the help of Porter’s five forces analysis and further highlights the competitive scenario across different levels of the value chain. In all, the report provides detailed analysis of the global deep packet inspection market along with the market forecast, in terms of revenue (USD million) for all the segments during the forecast period from 2012 to 2018.
