Capture and analyze Internet and Local Area Network packets

See a complete picture of actual traffic on your systems and LAN segments. CommView captures every packet on the wire enabling you to examine, save, filter, import and export captured packets, and view protocol decodes down to the lowest layer with full analysis.

Visibility to data packets enables you pinpoint network problems, debug network-oriented applications, and identify security threats.


 

FEATURES:

Captures all data packets flowing through a PC or LAN segment
Every data packet on the Ethernet wire or dial-up Internet connection is captured, enabling you to see the actual traffic information such as a list of packets and network connections, vital statistics, and protocol distribution.

Automated alarms notify you about important events
An array of alarm notification options will warn you of important events such as displaying a message, playing a sound, launching an application, or sending an email. A flexible system of filters enables you to concentrate on critical packets and events, filters may be set on protocol, MAC or IP address, port, text string, our advanced Boolean rules.




Protocol decoding
With over 70 supported protocols, see every detail of a captured packet using a convenient tree structure to display protocol layers and packet headers. You can even plug in custom decoding modules using the open interface.

Reconstructs TCP data streams
See easy to read information on current and past TCP session between different network hosts. With a simple click you can watch the contents of any TCP session, such as an HTTP client-server conversation or a POP3 mail download shown as ASCII text.

Generates traffic reports in real time
Customizable reports provide real-time statistical data that covers network utilization, top LAN talkers, protocol distribution, errors and more, all in HTML or text format.




Enables real-time browsing of captured and decoded packets
See live packets as they enter or leave your PC or network, or log individual or all packets to files then load and view capture files offline.

Data Exchange
Easily import and export capture files in many different file formats compatible with other popular data analysis applications.

HOW CAN PACKET ANALYSIS 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 packet-sniffing tool. 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 can 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, protocol decoder, or, more frequently, as a 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.
