Deep Packet Inspection (DPI) SDK

Modern attacks increasingly blend into normal traffic patterns — hiding inside encrypted channels, legitimate protocols, and routine network flows.

VoidStarIndia’s Deep Packet Inspection (DPI) SDK delivers fast, accurate, and scalable packet analysis designed for next-generation cybersecurity products.

And we don’t stop at delivering an SDK. We customize it, extend it, and integrate it directly into your platform, ensuring the DPI engine works seamlessly with your architecture.

FAQs — Deep Packet Inspection (DPI) SDK

1. Do you only provide the SDK, or do you integrate it as well?

We provide the SDK along with full customization and integration support. Our team ensures it meshes perfectly with your existing capture pipeline, policy flow, and architecture.

2. Which protocols does your DPI engine support?

Our DPI engine supports a wide range of L3–L7 protocols including:
HTTP/HTTPS, DNS, TLS, SSH, FTP, SMB, QUIC, RTP, VoIP, custom protocols — plus extendable parsers for industry-specific needs.

3. Can the DPI engine work with encrypted traffic?

Yes, we support both HTTP and HTTPS traffic analysis. With our DPI SDK you can do: Metadata analysis, Traffic behavioral profiling, TLS fingerprinting.

4. Is the SDK compatible with high-throughput environments?

Yes. It is optimized for:

  • Multi-core packet processing
  • Real-time inline inspection
  • Low-latency appliances
5. Can DPI be combined with our threat intelligence or ML models?

Absolutely.
We provide hooks to:

  • Inject threat intel feeds
  • Forward features to ML-based anomaly engines
  • Trigger policy actions based on detections
6. Do you offer URL categorization or just filtering?

We provide:

  • URL filtering
  • Integration with your existing categorization DB
  • Custom logic for sector-specific filtering
7. Will we get source code access?

We provide full source licensing
