Wireshark vs Xplico

Wireshark is a free network protocol analyzer for capturing and examining network traffic. It supports live capture and offline analysis through a graphical interface or the TShark terminal utility, and can inspect hundreds of protocols. Display filters narrow what appears during analysis, though their syntax differs from capture filters. Wireshark reads and writes capture formats including pcap and pcapng, and can decompress gzip-compressed files. Analysis features include VoIP tools, packet coloring rules, and exports to XML, PostScript, CSV, or plain text. It can decrypt traffic for protocols including IPsec, Kerberos, SSL/TLS, WEP, and WPA/WPA2. The software is available for Linux, macOS, and Windows under GNU General Public License version 2, with no license fee for the full version. Windows packages include Npcap, which is needed for live packet capture. What a capture can show depends on the operating system, capture library, network interface, and network configuration; switched networks may not expose unicast traffic between other ports. Community help is available through a Q&A site and users mailing list.

Xplico is free, open-source network forensic software that extracts application data from PCAP traffic captures. It can recover email, HTTP content, VoIP calls, and FTP or TFTP data, with protocol support for HTTP, SIP, IMAP, POP, SMTP, TCP, UDP, and IPv6. Port Independent Protocol Identification recognizes application protocols without depending on port numbers. Processing supports multithreading and realtime operation, although speed depends on flows, protocol types, and computer resources. Results can be written to files or SQLite and MySQL databases. A web interface lets concurrent users manage one or more cases, using SQLite, MySQL, or PostgreSQL as a backend. Modular capture, dissector, and dispatcher components can target files, databases, or network sockets. Downloads cover Fedora, CentOS/RHEL, and Ubuntu, alongside source code and a VirtualBox image. The free plan costs nothing; data-entry and input-file counts are unrestricted, with hard-drive size as the stated limit.
