RedSplice Network Analyzer review
A focused desktop analyzer for reconstructing, decoding, and replaying network traffic.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
RedSplice Network Analyzer is a desktop network traffic sniffer for security researchers, forensic specialists, application and web developers, network administrators, and other technical users. It supports promiscuous packet capture, traffic replay, TCP session reconstruction, protocol decoding, content extraction, keyword filtering, and network statistics with bandwidth monitoring. Capture sources include both local and remote traffic, while flow analysis and SSL/TLS decryption support extend its inspection scope. The result is a focused tool for technical users who need to reconstruct and inspect network activity from a desktop environment.
Its standout capability is the combination of session reconstruction, content extraction, replay, and protocol decoding. RedSplice supports more than 25 protocols, which gives users a broad inspection surface without changing the product’s central focus on traffic analysis. Passive and active SSL/TLS traffic decryption are also included. These features make it suitable for investigating application behavior, reviewing captured sessions, and tracing content through network flows. Keyword filtering and bandwidth statistics add practical ways to narrow investigations and understand traffic volume.
RedSplice offers Free and Professional editions, with a 15-day trial. The Free edition is limited to local traffic, while Professional adds non-local captured-data decoding and additional capture capabilities. That division makes the product more appropriate for users who need desktop-based inspection of local or selected remote traffic than for teams seeking a broader shared analysis environment. Choose RedSplice for packet capture, reconstruction, decryption, and protocol inspection in one desktop tool; consider an alternative if your priority is a platform-oriented workflow beyond desktop analysis or broader edition flexibility.
