A protocol analyzer (also known as a network analyzer, packet sniffer, or protocol sniffer) is a tool used to capture and analyze network traffic. It intercepts and logs data packets transmitted over a network, allowing users to examine the contents of these packets and diagnose network issues, monitor network performance, and detect security threats. Protocol analyzers are used by network administrators, security professionals, and developers to troubleshoot network problems, analyze network protocols, and identify malicious activity.
