Wireshark

Wireshark is a network analysis tool that captures and displays data traveling across a computer network. It allows users to see detailed information about network traffic, such as messages sent between devices, helping identify issues, monitor activity, or troubleshoot problems. Think of it as a highly detailed, real-time "window" into what data is moving through a network, making it useful for network administrators, security analysts, and IT professionals to understand and secure digital communications effectively.
