CommView
Overview
CommView is a powerful network monitor and analyzer designed for LAN administrators, security
professionals, network programmers, home users…virtually anyone who wants a full picture of the traffic
flowing through a PC or LAN segment. 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.
The newest CommView version 7.0 introduced SSL/TLS traffic decryption on the fly. A traditional
packet-capture tool is useless when you need to inspect the contents of an encrypted session, be it your
browser downloading a webpage or some application that contacts an unknown server for an obscure reason.
Today, virtually all network traffic is encrypted. CommView 7.0 is a game-changer: It intercepts SSL and
TLS traffic and displays the contents as if you were capturing an unencrypted TCP session.
CommView includes a VoIP analyzer for in-depth
analysis, recording,
and playback of SIP and H.323 voice communications. For remote monitoring tasks, you can use our
special, optional add-on for CommView: CommView Remote
Agent. It allows
CommView users to capture network traffic on any computer where Remote Agent is running, regardless of the
computer's physical location. This powerful and unique technology broadens your monitoring range: you are no
longer limited by your LAN segment or personal computer.

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. A number of case
studies describe
real-world applications of CommView in business, government, and education sectors.
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, Promiscuous Monitoring in
Ethernet and Wi-Fi Networks, 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.
What You Can Do with CommView
