How does wireshark differ from netwitness investigator?

Wireshark is an open-source packet analysis tool primarily used for capturing and inspecting network traffic in real-time, allowing users to analyze protocols and troubleshoot network issues. In contrast, NetWitness Investigator is a commercial security tool focused on threat detection and incident response, providing advanced analytics, security monitoring, and visualization of network data. While Wireshark is more suited for detailed packet-level analysis, NetWitness emphasizes security and forensics, making it more tailored for cybersecurity professionals.
