Whether you are a student analyzing your first ping packet, a sysadmin hunting down a memory leak, a pentester crafting a custom exploit, or a CISO responding to an incident, Wireshark is the one tool you can always rely on—and you can install it on any machine within two minutes, at no cost.

Originally named Ethereal (created by Gerald Combs in 1998), the tool was later renamed to Wireshark. Today, it is actively maintained by a global team of volunteers and sponsored by several tech companies, all while remaining open-source under the GNU General Public License (GPL). In an era where many professional-grade software tools require expensive subscriptions or licenses, Wireshark stands as a pillar of the open-source philosophy. There is no "Pro" version. There are no hidden fees, no feature paywalls, no time-limited trials. What you download from wireshark.org is the full, unrestricted application.
