The global market for Deep Packet Inspection (DPI) is projected to reach US$3.7 Billion by 2025, driven by exploding Internet traffic, rising security threats, growing sophistication of cyber-attacks and increasing bandwidth management needs. The unprecedented spurt in global IP traffic is the result of rapidly expanding internet user base supported by growing literacy rates, increasing disposable incomes & high proportion of digitally savvy young people; and rapid penetration of cloud computing based business models. Increased data volume amplifies security threats, while growing ubiquity of cloud services magnifies the need for protection against web exploits, data exfiltration and malware/ botnets. The need to identify traffic on a network is becoming more important than ever to troubleshoot poor network performance, latency issues and high application response times; to manage unidentified network traffic; to handle unexpected traffic and data volume surges; and classify network traffic by their importance i.e. business, social and prioritize accordingly. Also, a growing number of governments worldwide are tracking and monitoring their citizens and their communications for anti-terrorism spying, policing and e-governance purposes. This trend is resulting in governments worldwide intercepting, monitoring and decrypting information generated, transmitted, received and stored by computers in a country. Public sector use of DPI for national level surveillance and censorship is poised to gain significantly in the coming years. DPI provides added security by examining packet content as against conventional filtering that checks just packet headers. Read More…
