Network Recorder

Designed for Network Operations Center (NOC) and Security Operations Center (SOC) environments, HammerHead is a high-speed, continuous recording solution that provides full packet capture of traffic for retrospective network analysis and replay.
HammerHead Network Recorder combines flow-based session analytics with stream-to-disk recording at up to 20 Gbps, delivering an easily-searchable, back-in-time view of network trends and events.
Full Packet Capture with Flow Indexing
Even on the busiest networks, HammerHead captures 100% of the traffic, timestamping every packet with nanosecond resolution, and extracting flow identification parameters. As traffic is streamed to disk, HammerHead generates a flow and time-based index that allows rapid search and retrieval of targeted traffic from many terabytes of capture records. HammerHead’s browser-based drill-down interface allows remote analysis of selected packets without the need to export entire PCAP files. Alternatively, traffic can be retrieved in industry-standard PCAP format for analysis by external tools such as Wireshark ™.

- Dynamic rewrite of MAC/IP addresses during replay
- Store and export in ndustry-standard PCAP format
- Simple RESTful API for custom integration
Target Applications
- Forensic analysis and trending
- Root-cause analysis with fine-grained traffic history
- Post-event troubleshooting and analysis

Network Probe
HammerHead Network Probe is a flow-based meter designed for wire-speed network auditing and security monitoring. The flow exporter supports Neflow v5, v9, and IPFIX. In addition, the flow engine supports a plug-in architecture for easy integration with third-party or custom applications.

Boost traffic analysis and visibility
Boost traffic analysis and visibility by tracking hundreds of thousands of flows per minute. Using hardware-accelerated monitoring ports, HammerHead Probe captures 100% of network traffic — up to 14.8 million packets per second on 10-Gigabit links – without having to sample. As a result, it delivers higher performance and finer reporting granularity than is typically possible with standard Netflow exporters or software agents built into many network devices.
Key Features
- Line-rate packet capture to 10 Gbps
- Native Netflow v5/v9 export
- IPFIX export when integrated with YAF
- Plug-in architecture for custom decoders
- Works with standard collectors and analyzers
- Support for IPv4 and IPv6 traffic
- Simple web-based management over SSL
