What are advantages and disadvantages of data packet analyzer?

Data packet analyzers, or packet sniffers, offer several advantages, including the ability to monitor network traffic in real-time, troubleshoot connectivity issues, and enhance security by detecting unauthorized access or anomalies. However, they also have disadvantages, such as the potential for privacy violations if sensitive data is intercepted, and the requirement for technical expertise to interpret the captured data effectively. Additionally, improper use can lead to network performance degradation or be employed for malicious activities.
