Wireshark is free software that analyzes the data that travels to and from your computer network and allows you to learn about them.

Each Windows package comes with the latest stable release of Npcap, which is required for live packet capture!

Wireshark, formerly Ethereal, is a program that can analyze all TCP / IP messages on any network card (Ethernet card or modem) connected to the computer. 

  • Can analyze 602 protocols
  • Can capture packages and save them to a file
  • Can open a previously saved file
  • Can analyze in real time
  • Can filter an analysis (eg “show only HTTP messages”)
  • Can be used with terminal or user interface

Is Wireshark illegal?

Wireshark is an open‐source tool used for capturing network traffic and analyzing packets at an extremely granular level.  

Is Wireshark safe to download?

Yes, it’s safe to install so long as you get it from a trustworthy source, probably Wireshark itself for preference. Same for winpcap, which is just a Windows port of the libpcap packet capture library.

Wireshark , formerly Ethereal, is a network analysis application. The application that captures the data requests that reach your computer, allows you to view the content of these data packets. Using Wireshark , for example, by connecting to a website, you can examine the connection requests that this site sends to your network card and save the packages to your computer.

Using the program, you can examine all the data in your network. It can understand how protocols in the network work and can be used to detect problems in the network. The program that also makes rich VoIP analyzes tcpdump (libpcap), Pcap NG, Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, NetScreen snoop, Novell LANalyzer, RADCOM WAN / LAN Analyzer, Shomiti / Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek / TokenPeek / AiroPeekIt can read and write different formats such as. Live data analysis can also be performed from platforms such as Ethernet, IEEE 802.11, PPP / HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI. The program can give detailed analysis in XML, PostScript®, CSV formats.
