Report: State of open-source DPI - Challenges, opportunities and alternatives

Open-source DPI report

Is open-source DPI still keeping pace with today’s networks?

Open-source deep packet inspection (DPI) has made application-aware network analysis accessible to organizations without licensing costs or vendor lock-in. But as applications become more complex, encryption expands, and cyber threats evolve, the requirements for accurate, real-time traffic classification are changing fast.

This report examines whether open-source DPI can keep pace — and where its limitations may emerge.

Based on a survey of 48 leading vendors across networking, cybersecurity, and analytics, the report explores:

  • How increasing application complexity and encryption affect DPI accuracy
  • Which techniques open-source DPI uses today, including AI-based approaches
  • Whether existing signature libraries can keep up with new application and threat patterns
  • When evolving business and technical requirements drive organizations toward commercial DPI
  • How custom migration tools can simplify and accelerate the transition from open-source to commercial DPI

Get the report to understand where open-source DPI delivers — and where a commercial approach may be needed to meet evolving network visibility requirements.
