What RedSplice Network Analyzer is

RedSplice Network Analyzer is a desktop tool for capturing and examining network packets. It can capture traffic from other devices when the network adapter supports promiscuous mode, then correlate packets into sessions for inspection. Views include hexadecimal packets, extracted text, and data formatted for an application protocol. The product also lists content extraction, network statistics, keyword filtering, and protocol decoding. Users can edit captured packets and inject them into network traffic. SSL decryption is available in passive and active modes, but active decryption is limited to traffic generated on the local host. The Free edition costs nothing and is limited to local traffic and capture time; it includes a 15 Day Trial. The Professional edition includes unlimited capture time, decoding non-local captured data, packet sending, real-time statistics and charts, custom filters, an unlimited address book, and technical support. The maker identifies security researchers, forensic specialists, application or web developers, and network administrators as intended users. The maker also says the product lineage began in 1999 with a sniffer called Spynet, later known as Iris.
