Network Forensics Packages and Appliances

Expensive IP geolocation service.
Enterasys Dragon
Instrusion Detection System, includes session reconstruction.

ipfix/netflow v5/9
MNIS Collector is an IPFIX collector which also supports legacy Netflow. It was designed to be used with the MNIS Exporter, which is a Deep Packet Inspection probe that can be used to decode 300+ protocols on up to 20 Gbps and report the information in IPFIX.

Mantaro Network Intelligence Solutions (MNIS)
MNIS is a comprehensive and scalable network intelligence platform for network forensics and various other applications. It is built on high speed Deep Packet Inspection and metadata alerting. It can be used to understand network events before and after an event. It scales from LAN environments to 20 Gbps service provider networks.

IP geolocation services and data provider for offline geotagging. Free GeoLite country database. Programmable APIs.

netflow/flowtools Netflow Appliance (VMWare)
NetDetector is a full-featured appliance for network security surveillance, signature-based anomaly detection, analytics and forensics. It complements existing network security tools, such as firewalls, intrusion detection/prevention systems and switches/routers, to help provide comprehensive defense of hosted intellectual property, mission-critical network services and infrastructure

NetIntercept captures whole packets and reassembles up to 999,999 TCP connections at once, reconstructing files that were sent over your network and creating a database of its findings. It recognizes over 100 types of network protocols and file types, including web traffic, multimedia, email, and IM.
NetVCR delivers comprehensive real-time network, service and application performance management. It is an integrated, single-point solution that decisively replaces multiple network performance monitoring and troubleshooting systems. NetVCR’s scalable architecture easily adapts to data centers, core networks, remote branches or central offices for LAN and WAN requirements
NIKSUN Full Function Appliance
NIKSUN’s Full-Function Appliance combines the value of both NetDetector and NetVCR for complete network performance and security surveillance. This plug-and-play appliance offers customers a complete range of network security and performance monitoring solutions that identify, capture and analyze the root-cause of any security or network incident the first time! The unique enterprise-wide network visibility provided by this product is extremely attractive to large enterprises requiring an integrated and proactive solution to combat the constant barrage of security and network incidents such as worms, viruses, Trojan-horse attacks, Denial of Service (DoS) attacks, outages, overload and service slowdown, etc.
NetOmni provides global visibility across the network so IT professionals can manage multiple products and vendors from one central location. NetOmni streamlines the network management process in a manner conducive to a “best-practices” model that ensures Service Level Agreements (SLA), Quality of Services (QoS) and maximum revenue opportunities.
NISUN Puma Portable
NIKSUN's Puma, a portable network monitoring appliance, allows customers to leverage the state-of-the-art network performance, security and compliance monitoring technology as a robust luggable appliance that can be conveniently used in the field. Deployed in a few short steps, Puma offers with exceptional functionality of NIKSUN's renowned performance and security monitoring technology within minutes to field personnel. Puma, is now capable of monitoring networks at 10G speeds. The incorporation of real-time 10G monitoring to the Puma feature-set enhances the already excellent value that Puma provides to customers, making it the go-to portable monitoring and forensics tool for network professionals

ipfix/netflow v5/9
MNIS Collector is an IPFIX collector which also supports legacy Netflow. It was designed to be used with the MNIS Exporter, which is a Deep Packet Inspection probe that can be used to decode 300+ protocols on up to 20 Gbps and report the information in IPFIX.


NetSleuth is a free network analysis tool released under the GPL. NetSleuth can be used to analyse and fingerprint hosts from pcap files, designed for post event incident response and network forensics. It also supports a live sniffing mode, silently identifying and fingerprinting devices without needing to send any traffic onto a network.

NetworkMiner is a Network Forensic Analysis Tool (NFAT) for Windows. NetworkMiner can be used as a passive network sniffer/packet capturing tool in order to detect operating systems, sessions, hostnames, open ports etc. without putting any traffic on the network. NetworkMiner can also parse PCAP files for off-line analysis and to regenerate/reassemble transmitted files and certificates from PCAP files. The purpose of NetworkMiner is to collect data (such as forensic evidence) about hosts on the network rather than to collect data regarding the traffic on the network. The main view is host centric (information grouped per host) rather than packet centric (information showed as a list of packets/frames). NetworkMiner has, since the first release in 2007, become popular tool among incident responce teams as well as law enforcement. NetworkMiner is today used by companies and organizations all over the world.
NetworkMiner is available both as a free open source tool and as a commercial network forensics tool.
