Unsurprisingly, considering the full Enterprise version costs $995, the free build has a lot of restrictions. The program doesn't just understand and decode the basic internet protocols, for instance - it supports more than 300 (including VoIP). There's vastly more here, and real depth to Capsa's functionality. There's even a detailed breakdown of the exchange, so for example you might view an IP packet to check its IP flags or TTL value. Selecting any of these items displays the individual packets, and you can choose one, view any text it contains (maybe the password in a POP3 exchange, say). Maybe you want to zoom in? Choosing one of the Conversation tabs - TCP, say - allows you to drill down, see which packets went to/ from which addresses, the packet size, time sent, and more.Ĭolasoft Capsa 8 Free captures data packets, too, so you're not restricted to summaries. Click the Summary tab and you'll see the data behind the charts, the total numbers of IP and MAC addresses used in this session, the various protocols, DNS queries and responses, SMTP/ POP3/ IMAP 4 connections and a whole lot more. Just choosing an adapter and clicking 'Start' gets you an attractive dashboard, with graphs showing network utilisation, traffic, and top traffic by protocol and domain.īut that's just the start. Colasoft Capsa Free is a powerful tool for monitoring and analyzing network traffic (note, the free version can't monitor network wifi devices).
