Wireshark Training and Certification in Cork, Ireland

This course provides hands-on training in Wireshark, the industry-standard network protocol analyzer, used for packet analysis, troubleshooting, and network security monitoring. Participants will learn how to capture, filter, and analyze network traffic, identify security threats, diagnose network performance issues, and apply forensic techniques for deep packet inspection.
