Colasoft Capsa Free is an impressively powerful, comprehensive and feature-rich application that allows you to perform a very detailed and accurate analysis of a network. This thorough network analyzer is capable of monitoring network traffic and troubleshooting network problems as well. It comes with a jawbreaking high number of supported features and functions, including, just to name a few, support for over 300 network protocols and the ability to create and customize new ones, extensive packet analysis capabilities, messenger filters, mail monitoring functions, alarms, customizable reports with handy graphs, etc.
I personally like the fact that it's also capable of capturing and analyzing the TCP flow in order to detect issues such as slow website responses. This handy tool can also be used to perform security task like TCP scanning in order to accurately detect DoS (DDoS) attacks, ARP attacks, and other safety issues.
Despite being so comprehensive, Colasoft Capsa Free is also quite intutive. Thanks to the self-explanatory interface, it can be used by people with fewer advanced computer skills as well, such as those interested in learning about protocols, traffic monitoring, or network troubleshooting. It will also help professionals like network administrators or engineers quickly and easily detect and fix any network problems.
To sum it all up, Colasoft Capsa Free is a complete tool that makes it easy to perform packet sniffing, network analysis, traffic monitoring, and other similar tasks.
