About Sniffnet
Sniffnet is a cross-platform application to comfortably monitor your internet traffic. Written in Rust for performance, it identifies 6000+ upper-layer protocols, provides real-time bandwidth charts, supports PCAP capture and export, does IP geolocation and ASN lookup, and sends custom notifications based on traffic thresholds. The GUI is clean and accessible to both security professionals doing traffic analysis and regular users who want visibility into what their machine is communicating with. Supports filtering by protocol, country, and application.
About Zeek
Zeek (formerly Bro) is a powerful network analysis framework that sits on a network tap, link, or live interface and generates detailed logs describing network activity. Unlike traditional IDS systems that match signatures, Zeek performs deep protocol analysis to produce structured logs for every connection, DNS query, HTTP request, SSL certificate, file transfer, and dozens of other protocol events. These logs are the foundation for network security monitoring - they tell you not just that something happened, but exactly what happened at the application layer. Zeek's scripting language allows custom analysis, from detecting specific attack patterns to extracting files from network traffic. It's widely deployed in academic networks, enterprises, and government agencies, and its logs are commonly fed into SIEM platforms for correlation and alerting. Zeek also includes a signature framework for traditional pattern matching and a file analysis framework for extracting and inspecting transferred files.
