Line-Rate Intrusion Detection and Traffic Enforcement
Enabled real-time detection and enforcement of network security policies without throughput degradation or packet drops.
Situation
The client required deep packet inspection and threat detection at full network speed. Traditional IDS/IPS solutions introduced bottlenecks, dropped packets under load, or relied on sampling techniques that reduced effectiveness.
Solution
A hardware-accelerated inspection framework was implemented using FPGA-based parsing and rule evaluation. The system maintained full visibility and enforcement at line rate.
