Colasoft Capsa is a professional network analyzer (aka. protocol analyzer & packet sniffer) that performs real-time packet capturing, 24/7 network monitoring, advanced protocol analyzing, in-depth packet decoding, and automatic expert diagnosing. By giving you insights into all of your network's operations, Capsa makes it easy to isolate and solve network problems, identify network bottleneck and bandwidth use, and detect network vulnerabilities.

Network administrators can directly monitor http requests, email messages, DNS queries, as well as real-time activities and message details for the four most popular instant messengers: MSN, AIM, ICQ, and Yahoo Messenger.

Capsa is designed to be used by both IT professionals and novice users. Problems are clearly identified, and solutions are suggested in understandable terms. The program includes tables and graphs, as well as intuitive statistics and reports. Capsa has the tools that you would not find in other protocol analyzers, including tools to create and replay packets, and ping and scan IPs and MACs across the LAN.

What separates Capsa from other network sniffers is its unique ability to conduct quick drilldown analysis on a single workstation, protocol or packet. After locating a single item, it allows you to get comprehensive and dedicated information about that item.

Whether you're a network administrator who needs to identify, diagnose, and solve network problems quickly, an IT professional who wants to monitor user activities on the network, a security manager who needs to ensure that the corporation's communications assets are safe, or a consultant who has to quickly solve network problems for clients, Capsa has the tools that you need.

Capsa runs under Windows 2000/XP/2003/Vista. You can download a trial version of Capsa from the company's web site: http://www.colasoft.com/
