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. The Online Tutorial is an excellent resource for learning about the many exciting features CommView offers. 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.
