Network Forensics & Full-Fidelity Capture
Enabled continuous, lossless capture of network activity for forensic analysis without impacting operational systems.
Situation
The client needed the ability to reconstruct network events with full fidelity for investigative and compliance purposes. Existing solutions relied on sampling or storage-heavy architectures that could not guarantee completeness.
Solution
A streaming capture architecture was implemented directly on FPGA hardware. The system captured all traffic without introducing bottlenecks.
