About Wireshark
Wireshark is the world's most popular network protocol analyzer. It lets you capture and interactively browse the traffic running on a computer network. It has a rich feature set including deep inspection of hundreds of protocols, live capture and offline analysis, rich VoIP analysis, read/write support for many capture file formats, and powerful display filters. Wireshark is essential for network troubleshooting, security analysis, software development, and education.
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.
