Open Technologies Stack

---

Open Source  Application – 64-bit versions of YAF or Suricata, tuned and optimized for maximum performance.

Libpcap Extension – Standards-based, zero-copy, packet capture (PCAP) programming interface — derived from the BSD-licensed tcpdump project.

Packet Capture Engine – Wire-speed, multi-threaded packet capture engine, tightly integrated with a programmable hardware-accelerated packet capture adapter.

Intel Core i7 Processor (Nehalem) – State-of-the-art, multi-core processor  with deep cache, high memory bandwidth, and I/O throughput.

Programmable Packet Capture Adapter – Programmable PCIe adapter with FPGA-based high-resolution time-stamping, protocol decoding, multi-core load balancing, and high-throughput DMA.

Operating System – Rock-solid, security-hardened, GNU/Linux derived from Debian.
