This category of courses includes all our packet capture and analysis topics, including Wireshark, and our Capture the Flag challenges.  The courses in this category are 100% Instructor Led either in person at your site or a site close to you, or via Online meeting tools such as Zoom, Microsoft Teams, Google Meet, HP Rooms, or Webex.

Learning packet capture and analysis is one of the most valuable skills for anyone working in networking because:

  • Provides direct visibility into real network behavior at the protocol level
  • Reveals the actual packet exchange between devices when issues occur
  • Eliminates guesswork by analyzing real traffic instead of relying on logs or dashboards
  • Enables precise identification of issues across client, server, application, or network layers
  • Supports performance troubleshooting by exposing latency, loss, retransmissions, and protocol inefficiencies
  • Enhances security analysis by detecting malicious traffic patterns and data exfiltration, while building deep troubleshooting intuition
