Loaded with many user-friendly features, CommView combines performance and flexibility with an ease of use unmatched in the industry.

This application captures every packet on the wire to display important information such as a list of packets and network connections, vital statistics, protocol distribution charts, and so on. You can examine, save, filter, import and export captured packets, view protocol decodes down to the lowest layer with full analysis of over 100 supported protocols. With this information, CommView can help you pinpoint network problems and troubleshoot software and hardware.

How Can a Network Analyzer Help Me?

If you are a seasoned professional, you definitely know the answer. Managing a LAN, creating network-oriented software, or performing a security audit have one thing in common: You're blind without a good network monitor. Every day, it helps you maintain efficient network data transmission, test firewalls and intrusion detection systems, or identify problems with network-based applications. And there is an important economic reason behind using a network analyzer: it costs a fraction of the price of information, time, software, and hardware that may potentially be lost or wasted by not using a network analyzer.

If you are new to networking, you'll find CommView extremely useful for understanding how the Internet and your LAN work. Being a network analyzer (also commonly referred to as a packet analyzer, network monitor, or packet sniffer), it captures and decodes network traffic and makes sense of it, allowing you to see what, where, and how information leaves and enters your computer -- which is critically important for a secure Internet experience.

Be sure to read our white paper that examines the problems related to the deployment and usage of software-based network monitoring solutions in wired and wireless LANs. It demonstrates the methods of achieving network traffic visibility in various network configurations that include hubs, switches, routers, etc.

No matter what user category you belong to, you can be certain that CommView is the right choice for your network monitoring solution.
