What is a Network Analyzer?

E-mail Print PDF

As per wiki's definition: "A network analyzer (also known as a packet analyzer, protocol analyzer or sniffer) is computer software or computer hardware that can intercept and log traffic passing over a digital network or part of a network. As data streams flow across the network, the analyzer captures each packet and, if needed, decodes and analyzes its content according to the appropriate RFC or other specifications."


Capsa Network Analyzer provides all-in-one and easy-to-use software solutions for users to analyze network performance, enhance network security and troubleshoot network problems.

To be specific, Capsa Network Analyzer can be used to:

  1. Display the binary data in packets to human-readable format
  2. Troubleshoot problems on the network
  3. Analyze the performance of a network to discover bottlenecks
  4. Capture network traffic for forensics and evidence
  5. Detect worm, virus and network attacks
  6. Debug network programs in the development stage
  7. Teach or learn network protocol knowledge

Quoting steven:
does it support cisco router, switches devices eg.

Hi Steven, Capsa just captures packets from the switch. You should care about which routers/switches support port mirroring (SPAN).
