RedSplice Network Analyzer

What RedSplice Network Analyzer is

RedSplice Network Analyzer captures and examines network traffic, organizing packets into sessions for inspection. It can capture traffic from other devices when the network adapter supports promiscuous mode. Session views show packets in hexadecimal, extracted text, or data formatted for an application protocol. Listed capabilities include content extraction, network statistics, keyword filtering, and protocol decoding. Users can edit captured packets and inject them back into network traffic. The software supports passive and active SSL traffic decryption, although active decryption applies only to traffic generated on the local host. The Free edition is limited to local traffic and capture time. Professional adds unlimited capture time, decoding of non-local captured data, packet sending, real-time statistics and charts, custom filters, an unlimited address book, and technical support; no Professional price is listed. The maker identifies security researchers, forensic specialists, application or web developers, and network administrators as intended users. The Free plan is listed as free and includes a 15 Day Trial. The product lineage, according to its maker, began in 1999 with a sniffer called Spynet, later known as Iris.

Who it suits

RedSplice may suit security researchers, forensic specialists, application or web developers, and network administrators who need to inspect captured traffic. Professional features address users who need non-local capture decoding or longer capture sessions.

Limits
