Wireshark

Wireshark is a widely used network protocol analyzer that captures and inspects packets transmitted across a network in real-time. It provides deep visibility into network traffic, allowing security professionals to detect and analyze suspicious activity, diagnose network issues, and understand communication flows. With extensive protocol support and detailed packet analysis, Wireshark is valuable in forensic investigations, troubleshooting, and monitoring. Its ability to capture traffic across numerous protocols and present data visually makes Wireshark a fundamental tool for network security assessments and incident response.
