Packet-Level Traffic Analysis with Wireshark from CYBER SECURITY TESTING PRO
Gain complete visibility into your IoT infrastructure with Wireshark, deployed and supported by Cyber Security Testing Pro for smart utility environments.
Solution Snapshot
Wireshark is the leading open-source packet analyzer used by cybersecurity professionals to dissect and examine network traffic at a granular level. At Cyber Security Testing Pro, we deploy Wireshark in utility-scale IoT environments to analyze, troubleshoot, and secure communication flows between distributed sensors, control systems, and cloud services. From capturing SCADA protocol exchanges to identifying unauthorized access attempts, Wireshark offers complete network transparency. With Cyber Security Testing Pro’s expertise and support, organizations across North America utilize Wireshark to optimize system performance and investigate potential vulnerabilities in real time.

Case Studies
U.S. Water Utility – Texas
Cyber Security Testing Pro used Wireshark to uncover a packet flooding issue caused by legacy sensors. Real-time filtering helped the team isolate faulty broadcast traffic, reducing network latency by 60% and restoring normal SCADA operation.
U.S. Renewable Energy Operator – California
During an IoT gateway upgrade, Wireshark identified a TLS handshake failure due to mismatched firmware. Cyber Security Testing Pro’s team used captured traces to correct firmware versions, avoiding downtime and ensuring encryption compliance.
Canadian Smart Grid Provider – Ontario
A Canadian energy company partnered with Cyber Security Testing Pro to implement Wireshark for grid monitoring. Packet analysis helped them detect spoofed Modbus commands, leading to enhanced firewall rules and incident logging procedures.
